My question for everyone is what set up do you use for an overloaded 8,000 lb 100 Series. I have spent the past four years reading posts here, so I thought I would summarize what I have, and get your thoughts.

What I use the truck for:I use the truck for a dedicated camping/hiking/hunting truck. It has evolved over time and I hate to think of how much money I have spent, BUT it has taken me places in Mexico, Utah, AZ, and CA that few if any people will ever see, all in reliable & ridiculous comfort. I have done some of the tougher trails like Hole in the Rock, Elephant Hill, Dollhouse, all with nearly 8,000lbs. But my real problem is not technical trails with rocks & ledges, it is getting there on a rutted out washboard road! In the desert and on fire service roads I drive faster than most (25-50mph) Washboard roads are my worst nightmare (think Race Track Road in Death Valley x 2), especially on a slight curve when not paying attention. Faster is better, but eventually I will crash if not careful. The easiest solution is to slow down. I know ask my wife...

Problems:Too much crap...My truck weighs 7,900lbs and handling was almost dangerous. It bottomed out so much that at times I thought the hits would bend or break the rear axle. (Baja Mexico is not a good place for this to happen) Going slow at 5mph is not an option all the time. If you have driven to or spent time in Baja/North Rim/Utah Maze/Saline Valley/Death Valley you will agree that hundreds of miles on washboard are inevitable, and driving faster is better sometimes. When I make mistakes and hit washouts or pot holes I want my truck to stay in one piece.

I have weighed this truck and almost puked when the scale said 8,000 lbs. The next time I loaded the truck I threw out stuff I did not need, and then weighed everything as I packed just to see what the hell I was puting in there. I hate to post this as it is embarrassing but I think most guys would find this interesting. I am no longer in denial, which is the first step to recovery. See my list below and tell me how much your truck weighs.

My Set Up for Heavy Truck:

Springs: I finally switched to the OME864 rear spring. A springs primary job is to support the desired load at the correct ride height. Not the empty truck but the fully loaded truck. If your truck squats and sits just off the bump stops get a heavier spring or bring less crap! (Air bags are great for some, but I chose not to do it for reasons I do not have time to get into here)


Shocks: This is the most under appreciated item on any truck. How many times have you used your winch? your lights? Most guys here have $15-30,000 (not including the gear inside) of crap on these trucks and nearly everyone runs tiny shocks that sell for $75. I have personally exploded two sets of OME shocks. They get hot and boil the fluid then the seals failed/ They DO NOT work when I need them most. I would bottom out on every bump. One 2" Remote Resevoir Shock is the same as 2-3 OME shocks per corner. One 2.5" Remote Res shock is the same as 4-6 OME shocks per corner!!!!. Most shock manufacturers agree that for this truck fully loaded we need a 2.5" remote res shock and would really recommend a 3" shock for 8,000lbs (if it would fit but it won't). Have you ever had your heart stop on a washboard or rutted road on a slight bend in the road when you felt you truck skipping towards the ditch? Your wife screams, and yells slow down, and you need 5 minutes just to calm down? When the OME shock fluid is boiling hot and not functioning your tires will bounce and skip you right into a ditch! If you don't belive me then just feel how hot your OME shocks are after driving on a washboard road for 30 minutes. After a while you will not be able to touch them. 90% of the people here who comment on what shocks to buy, have not compared handling on a truck with good shocks and one without. (think Ford Raptor vs Ford F150) The Raptor is the same truck with suspension mods. Shocks are the biggest expense in a typical suspension upgrade and by far the most important component. These things can be expensive at $400 per corner! I have spent countless hours under my truck measuring droop and wheel travel. I will not debate what size or brand to use, I live in Orange County CA and can drive 30 mintues to King Shocks, Fox, Rad Flo, Icon, etc... I have bugged everyone of them including Christo about this subject. After years of trying to find a 2.5" remote res shock I finally went to King Shocks. They needed a donor truck to design a 2.5" bolt in kit for the IFS UZJ100. They had my truck for two weeks building brackets and measuring for droop and clearance. They should have production started soon. (I will post pictures later) AGAIN, I cannot tell you what shock or length of shock to buy, but when I think about all the money I spent before this upgrade it is almost laughable I did not upgrade earlier.

Bump Stops: 100 series trucks are a mystery when it comes to rear bump stops. Some have them and some don't. The shock itself is not designed to stop the truck from bottoming out. If you do not have bump stops your lower shock mount will take the hit and most likely explode your shock. Many here think droop is more important for rock crawling, and I wont argue that, but reducing up-travel (by having to lower your bump stops) to absorb big hits is a major compromise. It is the up-travel I need driving through places like Death Valley in order to absorb the bumps/ditches, and potholes.

Rear Sway Bar Link Extension: Not many people extend their link ends but I think it is something to look into. If you raise the truck 2 inches then the sway bar is loaded up more than it's intended to be. I plan to do this mod this winter, and add between 40-50mm.

Front Suspension: There is not much to do yet. Adding a new aftermarket Upper Control Arm from Total Choas or Carl at Just Differential's is the only real mod. It allows people to run a slightly longer shock that allows for a little more droop (.5"-1") For those new to this subject the Stock UCA is is the limiting factor in droop. If you run a longer shock the the UCA will hit the shock before the shock is fully extended and you will need limiting straps. I run the Slee diff drop as well to help with excessive CV angles but I do not have any problems. They CV shafts in these trucks are nearly bomb proof. They might leak a little for some but who cares. Mine don't. FYI Total Choas just finished their new UCA for the 100. They had my truck for 2 weeks doing final fitment, so prodcution should start soon.

Brakes: I have read so many posts on this subject but still not sure if there is a definitive answer. I do not care about brake pad longevity, I just want better stopping power. Is there a documented stopping difference for the different options? I plan to add braided brake lines at some point, but mainly to avoid over extending the stock lines, and to avoid a rupture from flying debris. Any ideas on the best setup would be great.

Guys let me know your thoughts on how you set up your 8,000lb Land Cruiser. (besides leaving stuff at home) I would love to hear about your set up, and especially your springs, bump stops etc... Also how much does your truck weigh fully loaded for a week long trip?
 
Desert Run - Does King have a bolt in solution now for the 100? Are they offering a remote resovoir and a mono tube option or only a high end $400 per corner option?

Good luck on the build... Sounds like you are well on the way to a pretty sick rig... I'll let the seasoned vets chime in to answer your heavy load questions...
 
Desert, you're bringing up exactly what I tried to two years ago with the shock for high speed thread.

My truck pre-rack mounted gear or any camping stuff(just recovery gear minus hilift) or my fridge weighed in at 6620 one day just passing a scale. I'll have to weigh in again but I'm going to think somewhere around 7500 to 7900 like yours.

I like yourself have hit those washes and ruts at higher speed like you mentioned out in the death/saline areas and in other places out here in the desert. As much high speed stuff, I also do slower stuff up in the forests so kind of need a well rounded setup instead of all Baja.

I really want the King shocks like you have (for the 2.5" setup) and have been waiting on other options on the front UCAs.


After driving a F150 Raptor and my 100 on OME Sport-Firm shocks/tbars and slee rear springs....I knew I'd have to do something more significant and it seems like now is about the time I need to do it.


For brakes I'm running stock pads with Slee rotors.

Sway bar links I'd like to extend as well.

Rear bump stops had to be lowered due to my tire rubbing the slee bumper but, I think I'm going to massage the bumper and remove the bumpstops, having the reduced travel at higher speeds REALLY sucks.

You can call Mike at King Shocks if you want to order a set. Tell him you want the new 100 series shocks that were just developed for the white 100 that was in his shop two weeks ago. They just finished with my truck and said they would have the kit up on the site soon. The shocks will be the same price as the OEM Performance Kits they offer on their site. The front is a remote res with a bracket for the reservoir. The rear are piggy back style. Both are have top pin mounts and just bolt in. I will post some pics mid week when I get back into town.

King will have the 2.5" kit up on the site soon, One thing they have that is very cool is the compression adjuster. It is not just restricting the flow of fluid between the reservoir and the main tube. It is a true check valve allowing fluid to flow back instantly. The difference will be from teeth shattering stiffness for hard core high speed use, and less for more technical trails. I do not belive the Fox Shocks have this check valve, but I could be wrong. If you do a little research post it back here. I plan to trail test these shocks a bunch more over New Year's weekend and will post back.

Here is the info from the website "King 2.0 and 2.5 shocks have a new level of versatility and performance. King shocks with our Wide Range Compression Adjuster give you the ability to precisely adjust compression from super soft to super firm with the simple twist of a knob. The clearly marked knob offers 16 positive clicks of finely tuned adjustment. You can soften your ride when just cruising or firm up the compression when hammering rough terrain or carrying additional payload. You’ll have the ultimate in performance regardless of your pursuit. Existing King shock owners are not left out when it comes to the added performance offered by the Wide Range Compression Adjuster. Your shocks can be easily upgraded with the new technology. King is continuously striving to bring you the most innovative and best performing shocks in the world."

After my truck was at King Shocks it went straight to Total Choas. They work closely together in developing aftermarket parts. Nicole at TC can hep you with ordering them even before they have them up on this website. They claim some solid improvements over what is out there, so I will be interested in how they perform. Also if you want to talk about a coil over conversions for the 100 Series PM me some time. I spent hours with Total Choas working on a possible long arm kit and have lots of info. It will be tough but they have not ruled it out. Total Chaos is one of the best out there so if anyone can do it, they can.
 
are replacement(TC/Carl) front UCAs required?
King supposedly designed the front shocks for stock OEM arms, but I cannot tell you for sure since my truck had Carls new UCA's at the time they did the R &D. You can ask for Richie who did the research and work on the truck. He had a stock OEM UCA along with Carl's UCA installed on my truck to compare so I assume they will fit fine. One thing to keep in mind is that they can design the shock length at any measurement. So if the stock oem arm hits the shock you could always request that it be 1/2 inch shorter to avoid hitting it.

I will have the extra set of Carls UCA's if you want to buy them. They have only 5,000 miles on them. The TC ARM's were developed awhile back but needed a donor truck for a final fitting before going to powder coat. I think the long time TC customers in Austrailia and the middle east finally kept bugging them to build one for distribution.

I saw, on the King site, they had some type of new "compression" adjuster. I'd like to see a cross section or hear how it works as the Fox merely restricts flow to the remote which is not a good way IMO to adjust valving; I tried it and didn't like it. Its hard to imagine they can somehow control valving with such a simple dial...

I am also interested in hearing more about their new internal bypass technology and whether it can be packaged in a 6.5" travel shock for front location; and of course how one tunes it.
 
Put me in the over 7000 Club. Started with OME shocks , t-bars and 866 w/Airlifts. Now have Fox shocks and Carl's UCA. The Airlifts provide the bumpstop for rear as stock bumpstop has been cut off to be only 2" tall. For brakes running stock rotors with Hawk LTS pads and modified Goodridge SS lines.

Very happy with braking. The Fox's were a big step up for the miles of washboard, but like Desert Run I would like better. Cruising (safely) North Rim/Utah Maze/Saline Valley/Death Valley washboard at 45mph+ would be worth a lot to me.

I have looked longingly at TC's long travel setup for late model 4Runners, wondering/wishing if it could be made to fit a 100.
 
Having ran a coil over and bumped stopped rig for a few years, I'd say hands down that would be my first choice, as I'm sure I wouldn't be alone in that preference.

However, to say that I'm pretty excited at the prospect of a 2.5" remote reservoir would be putting it mildly. I've been holding off on suspension mods because I'm trying to get the most out of what we have to work with. I have no interest in OME and had settled on King or Fox. I have spoken to King on two separate occasions regarding the 100 series. Once before I pulled the trigger on it and once since buying it, so my hat is off to you in what you were able to accomplish with them. Like you said, a 3" would be the proverbial cat's meow, but I'd jump on the chance for a 2.5". In fact, I'll be calling them tomorrow to discuss these.

It will be interesting to see the differences with Carl's and TC's UCA's. If you have any other tricks up your sleeve, see if you can pull out a bump stop setup please.

That is funny, I asked the same thing when I went in there. "Give me some Hydraulic or Air Bump stops!!!" But as you know they are tough to mount on IFS 100's because of the lack of room. It can be done with custom mounts and strike plates for front. Rear is easier but still a major pain. One thing to be careful of though is that those things can make some noise when they engage. The new ones are much better with delrin pads, but they still make a little noise when they engage depending on the type and where they are mounted. They told me to try the 2.5 inch shocks first and they see if I even need them. I plan to hit the trail this weekend a little more and will let you know. PM me some time and we can talk about what they told me when I was in their shop with the truck in the air.
 
Thanks for a good post on the GVM (Gross Vehicle Mass) issue of the LC/LX we all have.
Here in Oz there are strict laws on that, and we probably get close or exceed the GVM when we go on holidays/vacation towing and/or carrying various gear, provisions, etc.

My suspension is "totally rooted" now (Aussie for umm...well the F word with ed on the end).

As i pm'd another mudder on here, it's dangerous to drive now (dont tell anyone!!) , and i wont let anyone else drive it now. I may have mentioned that on here previously...whatever, bottom line is that my ARB bar and the winch and the lights etc have led i assume to the suspension being the way it is.

All of my mods that i wanted to do...supercharger etc...nope...have to take a back seat...i need new suspension.

So i'm looking short term (5 years???) at an Ironman Suspension solution $1250 AUD and given the Aussie dollar is the same as the USD at the moment that's good value for me.

My LC fully loaded is probably similar, but without the peoples/passengers weight.
Currently i only have the two front seats in it...the back reminds me of the troop carrier LC!! But i need to re-install the passenger seats as i'm taking some of my nieces/nephews to the Ada Tree soon.
cheers
peter

Edit: i'll be getting rear airbags too for when i tow.

DesertRun, I have no experience with Timbren but they might be worth looking into. They make these bumpstops to assist with heavier loads. Might be an easy and cheap alternative to hydraulic/air bumpstops for your usage... especially for the front where the bumpstop is minimal. It also looks like they have quite a variety of rubber springs/bumpstops for different needs.

Desertrun,

Any updates on how the kings are working out?
 
Wow...8000-pounds. Crap!

*No doubt you are salivating for a better shock.

*You addressed the rear spring by adding an 864.

*Have you though about addressing the front spring (T-bar) or do you feel the OME bar is adequate? You could add more rate by going with a Sway-A-Way bar. Even more support with an Ironman. The Ironman's are not good for crawling as they are too stiff. They might be perfect for you though for your application.

*With all that weight have you considered reinforcing those front lower control arms to prevent possible cracking like the diesel ones have had happen due to the added weight of the diesel motor. Weight is weight and those arms might be over-stressed.
 
So I just checked the wheel wells on my non lifted hundy and it appears that at full lock and in flexy situations there could be potential of tire rub on the reservoir or the tube at the chosen location. How is your clearance?
