I wasn't aware that IronMan springs were also progressive rate

That's the word on the 2" and 4" light springs

I hope you are right about Ironman springs being progressive. In the past couple months we installed an ironman 2" and TJM 2". The Ironman coils were definitely not progressive and the TJM coils were. Maybe Ironman has other coils that don't come with their 2" kit.
 
StoneMountain, Were you impressed with the TJM? did it have the rubber Control arm caster bushings? what was your impression of those guys?

Interesting I saw your post and did some digging while people have TOLD me they are progressive come to find out I can't find anything in writing that holds that as a true statement. Thanks for the comment it made me do some digging. If that is the case then TJM would be the only one with progressive springs.
 
I have the TJM lift and a club member has the ironman. I haven't talked to him since last month, but he likes the way it drives. I really like the TJM coils and shocks. Went offroading with 275 street tires and really like the way it drove. I just put on 315 Terra Grapplers and haven't hit the trail with them so I don't know about rubbing. I haven't pressed in the castor bushings yet. Steering was fine with 275s, but with 315s it's a little squirrely. Hopefully in the next 2 weeks I will get the bushings pressed in. Overall the TJM drives great and feels much improved over the stock suspension. It is smoother and has no body roll. My suspension was 16 years old and now it feels great! I imagine it will be even better with the castor bushings pressed in.
 
OME 2inch lift 295 tire no bumpers 97LX

I'm building a 97 LX for my son to take over as a first car. I bought a 97 just like it about 3 years ago built it with an OME 2inch medium lift with the nitro charger shocks and press in bushing castor correction. It became very stiff and seemed to steer to quickly. I did not have any weight on it other than stock truck. I sold it. Now I found another one exactly like it with lockers. I am going to do a mild build on it and try to keep the cost down so my son can buy it from me next year. I want this one to have near stock ride and control. I was thinking about OME 2heavy front medium rear with and ARB and 10000lb winch and MT or Slee step sliders BUT i was going to try Radflow 2.5 shocks with it (expensive). Now I find this thread and hear that their are PROGRESSIVE springs available in the US. I considered Frankie's progressive springs before but they were to tall for this. The TJM may fit the bill but are they really progressive and different from the OME???
 
Just my two cents worth.....

I have a 3" OME Lift kit w/ Dobinson spring's, OME LTR's, castor correction kit and steering damper. I LOVE the way it rides and handles on and off road. I cant comment on TJM (Good quality products) or Iron Man lift kits... BUT....in speaking to a few friends of mine who 1 owns a 4wd tyre and suspension shop that installs TJM, Iron Man, Tuff Dog and OME. The other is a ARB mechanic. They both say they get more Iron Man lifted rigs back/ or to be replaced w/ OME due to blown shocks, sagging springs and or just not happy with the feel of it then anything else.

Again, I have no first hand exp with TJM, Iron Man or Tuff Dog lift kits....only OME.

IMHO, this is most significant post so far in this thread. 8 yrs & 73K miles ago, I installed a OME lift kit, plus steering stabilizer and brake line extensions. Comfort is a relative term. Hey, it's a Landcruiser. If you're driving for comfort, you're in the wrong rig. Bigger tires and mods to "improve" off road performance are "generally" going to make it ride less comfortably, overall. There are exceptions, of course, but whatever OME is doing - works and lasts. OME may have a different "feel", but I can live with it for durability.
 
Ironman 4x4 Coils

Hey everyone,

It's Eli from Ironman 4x4/Camel 4x4, just wanted to add and clear a few things on this very long thread...

First, all our Toyota coils are linear rate, which means the rate is consistent throughout the travel.

All Our coils are shot peened to reduced stress on the steel and to improve durability.

A few year back, we acquired a new cold winding machine in the factory to cater for larger diameters. All our coils are cold wound coils, this is often more "desirable" than hot wound coils. One less heat treatment process and CNC wound ensures the consistency and durability.
Also all Ironman coils are “Bar Peeled” which means that the coil material is ground to an exacting size, rather than just utilising the raw size as supplied by the steel mill. This provides a consistent bar diameter to within 0.1mm.
One last thing, for the 80 series - the lift is a 2", 4" & 6" of a lift. We found it to work better with the 80 series body and weight.
I hope this helps, let me know if you need more.[/FONT]
Cheers

Ordered my TJM 2" Progressive Rate Kit today

My.02

For sole purposes of streetability, and ride quality, i went with TJM for the progressive springs and Rubber Castor correction bushings!\

In my experience, Rubber slaughters poly on the street. Secondly, my jeep is way to stiff to be staring down some OME heavies on the FJ!

Outside of the springs there is another factor to remember and that is the shocks paired with the springs you're using. There are a couple differences in the shocks that are in these kits that also affect the ride quality. One similarity in with all three of these companies is they use a twin tube design.

According to ARB the the new OME nitrocharger sports will give BMW (firmer ride quality), but these shocks have the first multi stage valving allowing for finer tuning of valving. This shock is also supposed to have a sweet spot for each style of bump or crack in the road depending on the speed your traveling at. While the Nitrocharger shocks will provide a Cadillac (softer ride quality). This shock is a standard 2 stage valving system that most shock companies use. This shock also uses a 18mm chrome piston rod for optimun rod strength.

TJM shocks have a 2.5 mm outer wall which from my research is the largest out of all three companies. With a larger outer wall it is very possible that TJM shocks will contain the most oil allow for better heat dissipation. They only state that they have any exclusive design valving system. They also use a 18 mm chrom piston rod for optimun rod strength.

Ironman has two options for shocks the Nitro Gas shocks and the Foam cell shocks. The Nitro Gas shocks are standard twin tube shock that from what the picture on the website show to be a two stage vavling sytem. The piston is only 15 mm and uses a 35 mm piston, which is the same size as most steering stabilizer on the market. Now the Foam cell shocks have a peice of foam placed inside the shock to help prevent foaming, but down side is if the shock is heated up the foam is damaged causing the shock not to perform properly. The Foam cell shocks appear to be a two stage valving sytem as well with a 18 mm piston rod.

Lastly is the warranty of the shock. Most companies will not warranty leakage because this is completely normal for a shock to leak small amounts of oil, but if the shock is dripping oil with in warranty period it may qualify for a warranty. The Nitrocharger sport and the TJM both carry a 3 year 35,000 mile warranty against manufacture defect. The OME Nitrocharger and Ironman shocks only carry a 2 year 24,000 mile warranty against manufacture defect.
 
FWIW, I switched from an OME J setup to the IronMan 4" 2 years ago. My 80 is a DD and gets wheeled fairly hard when I have the time.
There was a previous post saying that a Land Cruiser can't be a comfortable DD. That is nonsense. The IronMan setup is ridiculously more comfortable and stable than the OME setup I had. Axle articulation is the same as OME. I have had zero issues with any component and several GCLC members are now running this exact setup on their 80s as well. Each has commented on how nice the ride is. My wife even commented to me.
For a point of reference, I've been through 4 different suspension systems on my truck. The IronMan is by far the best.

Suspension setups are very subjective. What works for one might not work for another. I have been extremely happy with this setup and the truck drives better than it has in years. My install and first impression can be seen here:

I swapped out my front OME J springs for Ironman4x4 springs last fall.
To be honest I was a little hesitant on it because they were a new name to our market.
Ironman has been around for awhile but just not here in the US so I figured I would give them a shot.

HUGE difference, truck didn't nose dive when the brakes were applied hard.
Smooth ride off road and articulated just as well as any other spring.
Feels much more stable while cornering and really just had a more comfortable ride.

In preparation for my 4,000 mile road trip this summer I have decided to swap out the rears also and will be looking into other Ironman4x4 suspension options as well.

With all of these types of opinions, it sounds like OME might be trying to ride along on their good name... and not offer as quality a product as in the past!

I hope I'm as happy with my TJM as you guys are with the IronMan!

I've been intently watching this thread as I too am about to purchase a 2.5" kit. I thought I was going OME but decided I might consider TJM after reading everything. I can't find any TJM 2.5" kits. The Slee site suggest they have stopped production... WTF?

Also it appears from the pics the TJM rubber bushings are not offset like the OME bushings. Is this true? I have had poly suspension bushings in other vehicles before and I would prefer to have rubber offset bushing for my LC if they exist.

ADDENDUM:
I did find a TJM kit at TOYTEC.
http://www.toyteclifts.com/index.ph...age.tpl&pop=0&option=com_virtuemart&Itemid=72
They only offer light (progressive) and heavy spring options. I was thinking medium was what I wanted... Still unsure/confused.
