Yezz, another sweet issue. And great to see more 100/LX coverage!

In the follow-up article regarding Christo's LX, there are a couple of errors in there as to upgrades and modifications. For those looking to buy a new rig, or modify their existing 100/LX, I thought I'd point these out as they could make a difference. Please note I'm not trying to be critical. I'm relaying information from my own (and others) experience about our non-LX 100-series model:

********************************

Adjustable Height Control (AHS): The article states a 6-inch spread...."2-inch below centerline to 4-inch above centerline. Lexus (in their specs) claims:

"When it comes time for the inevitable loading and unloading scenarios, you'll thoroughly enjoy the luxury of Adjustable Height Control (AHC), a rather hospitable amenity that permits the LX to be raised 1.6 inches or lowered 1.2 inches."
http://www.lexus.com/models/lx/performance.html

That makes for a 3.8 inch spread. Of that, only 1.6 inches of that is actual suspension lift. So as you see, the LX does not have a 4-inch on-board lift available to it. If I remember correctly, Christo's measurement between his LX and my 100 was under a 1-inch difference (the LX of course having the advantage due to the hydro suspension.). So, under an inch advantage may not be worth the added cost to aquire and modify an LX, nor does this make a big difference toward upsizing to 35-inch tires as the writer says.

********************************

The article states "With a twist of a button, some springs and bars, and you have 35's on OEM wheels"......"Take the same T-bars and OME coils without the hydraulic suspension and you can barely sqeeze 33's on a 100-series."

1. 33-inch tires fit without issue on a STOCK 100. Tons of stock owners are running 33's and 285x75-16 (33's) tires now. One does not need to add Tbars and coils to run 33's.
2. 35-inch tires fit on a non-hydraulic suspended 100 and possibly with easier overall labor and modifications compared to an LX. There are many shops and shade tree mechanics that can do the mods to a 100 to fit 35-inch tires (T-bars, coils, diff lowering etc). To gain the "LX advantage" (of under an inch) one needs to "trick the system". Not sure how difficult that is but there is a need for unique expertise in doing that.
3. Unrelated article issues, though comments regarding the two rigs:
A. Reliability might be an issue on the LX hydro susupension?
B. Cost of the LX hydraulic shocks are extremely high.
C. Advantage of auto ride height control in the LX reardless of load is a plus.
D. A bit more down-travel gained by having the LX hydro suspension.

********************************

The artical states "The Slee bumper is a must if you plan on running 35-inch tires and carrying a spare."

This is not so. A 35-inch spare fits within the stock location under the truck as long as you remove your trailer hitch. If you need to tow, a 35-incher will not fit though a 33" will.

Actually, 315/75R16 is equal to a 35. Typo, you meant to say 305/75R16.

You know Shottz you are one smart feller............... :flipoff2:

Thanks Carl. I changed that in the post to a 285x75. A 305x75 is a 34 I think. I'd have to check. J


305/70 = 32.8 x 12 Same diam as 285/75 but .78 inches wider.

I'll add a little more detail concerning the AHC on the LX. There is more than a 3.8" spread and less than a 6" spread. I thought the 6" spread maybe was referring to Christo's modified AHC system. Anyhow the spread on a stock LX approaches 5" from loading up grandma to taking her down your favorite trails. Here is the breakdown"



LX470...........Front Rear
Low..............-2.0 -1.6
Normal......... --- ---
High.............+1.6 +2.0
Extra High....+2.8 +2.8

Don't have a clue about the tire issue but I know that 33's are nowhere close to rubbing on my LX and I think a 35 would have to get stuffed a fair bit to rub. We don't have too many boulders laying in our trails here in SC which almost made me go with the 35's but didn't see that anyone had done it on here without upgrading so I didn't. :flipoff2: :D
 
305/75/16

I just got 305/75/16 terra grapplers installed on my stock 99 uzj, w/ t-bars cranked about 1". I had to demand they put them on, as they said the tires would not fit. They fit perfectly.

Lets see some pics with the 305 terra grapplers. Those are the next tires I am considering.

Thank you,

I will try to get some pics. Don't have a camera w/ me. I ditched the running boards to. Already moved it from soccer grandma looking to a soccer mom looking truck. I can say that I do like the nittos, I have had many bfgs and goodyears. They look pretty good for an at, and are pretty quiet.

Agree, let's see the pics! Although I hope I don't like it too much, I just put the 285's on my stock '99.

Agreed, Nolen got it a little wrong on that point.

What is important to know is that you do not have to fit different springs and torsion bars to get the extra lift. We did it due to the excessive weight we carried in the truck. You can push the button, got 2" of lift and fit 35's. The only thing that you have to do if defeat the height drop down feature.

Also, if you run 33's you can get more ground clearance when you go off-road by just pushing a button. The rest of the time you can run at stock height.

See earlier point. Not really,

Possible, but never experienced it.

ShottsUZJ100 said:

Yes, but worse case you rip the whole system out. I do like the memory seats, electric steering wheel, dash and some other features of the LX more than the 100 series.

ShottsUZJ100 said:

For most people this feature would be the nicest. No matter how we loaded the truck up, it always leveled out.

Never tried, but I do not believe I would have been able to get the Nitto's underneath there.

All in all, a good article. Nolen might have missed some points but I think he got the message accross. All in all LX's are just plain cooler than UZJ's :bounce:
 
I want the Mark Levinson Stereo in the 100! :)
(Wouldn't mind rear air springs either! :)

How difficult and time consuming was it to "trick" the AHS system into remaining on HIGH? Could a shade tree mechanic do it with some instruction?
 
Yes, there are folks very interested in a consumer black box or a similar solution. :)

I just looked up the tire sizes. Your Nitto's are 34.88 tall and 12.99 wide. My BFG KO's are 34.7 tall and 12.1 wide. I have about 3/4 an inch to spare before the spare hits the rear sway bar. So, your Nitto's would fit. They'd just hand 0.8 inches lower than mine. No biggee there as I rarely hit the tire. The bumper tow hooks usually hit first.

Yes, the article was awesome. I'd loved to go on that trip. Nobody quotes ALL the 0's and A's perfect every time. (especially me :D ) I thought this might help potential buyers or modifiers in making their decisions. I agree with you. The LX is cooler. Man, I want thatr stereo despite the JBL in the 100 being really good too. One BIG downfall though in owning an LX......it DOESN'T SAY "LAND CRUISER" ON IT. :D :D

I'm pretty sure you both mean 305/70-16 and not 305/75-16.
 
305/70/16

Yes, I meant 305/70/16
