Why is that?
I like the Rover V8, the ZF, the Ashcroft, the LT230, and the Rover/Toy hubrid axles. The Chassis is bomb proof, and the cab is nice and comfy...and easy to work on, spares are PLENTIFUL across the world and acros teh street for the past 9 years' of offroading...
It would be hard to get a truck to deliver on the same ingrediants and have a sweet combination - of course an LT1, Allison 5 speed auto, Atlass III, and mogs would be sweet, but I don't have easy access to these, their parts, or their $
, remember, I'm in Lebanon, a 4.2 V8 and ZF only cost me 400$ over and above my 3.5 and LT77s ...

Your Toyota axles are not going to hold onto your 42's.... People with 38's are already breaking the new 30-spline Longs......FWIW

Well, from Pirate 4x4, people with 39.5 boggers and healthy 350 Chevys are doing ok, so, given that I am lighter and less powerfull, plus IROKs are easier on the drivetrain, then I should be fine...If not, then I'll see how to loose more weight...

Just to compair, my friend has a 1983 toyota pick-up with a fiberglass bed off of a Toyota Trekker that has also been bobbed 20". He does have a full cage that adds weight. He's running 38x14.50 swamper TSL SX's on 10" beadlocks. It's a V6 fuel injected motor, 5-speed transmission, and a marlin crawler box, 4.7:1 I think, with 5.29 gears.
I know the Marlin box and 5.29 gears creates a lot of torque, but he's busted two 30-splines so far. Bobby has replaced them free, but broke is borke.
If your going to roll on 42's, I'd step up to a D60 or hi9 while your working on it.
I don't know, I guess time will tell, but I don't think it will hold.

I have to agree here. 37-38 is as big as you can safely go....even with lighter weight vehicles like yours will be.
Nadim,
good work. Unusual, creative and some funky ass good welding. Looking forward to seeing pictures of it complete.

I'll try to be Devil's advocate and be stubborn for a bit
I am not certain the set-up will hold 100%, but let me tell you this: 38" SXs have a rolling torque/weight, whatever you want to call it, far greater than a 42" IROK,
Also, an Auto is far smoother than a manual, and I am certain my total weight will be less than his.
I don't want to act stubborn, and worst case scenario, I'll slap in a 14b and D60, but I want to experiment and push the Rover set-up to the limit.
In a year's time with some more cash flow, I'll go with alum beadlocks, more plexi, and air shocks, which would easily save me a total of 250lbs more...
We'll learn and see

Nadim,
I agree with you on the Toy conversions. It seems more people like to speculate than to actually try something now days...

Leverage man Leverage
42" tyres are less torque/weight than 38" tyres???????
Take a lever which is 38" long and apply force on any object.
Then take a lever which is 42" long and apply the same force.
Which is greater?
I don't know which tyre is heavier, but weight is a minimal thing compared to torque. Shock load also hurts.
A friend of mine had a Toyota with 35" tyres on it and wheeled it with stock axles and gearing just added ez lockers and had no breakage. No surprise there, not enough torque to break anything. He then added a dual t-case and lower gears, I think the final was around 300 or so, insane if you ask me as that multiplied by the engines torque generation = 64000 fb lbs at 175. That leads to all kinds of trouble, he couldn't keep axles, gearing or joints under it. He now runs one T-case and unimog axles.
My point is that tyre size increases your chance of breakage, but if you don't have the torque you may get away with it. Good luck. I love the fact that you are trying something different.

Hey Larry, how many converts have you done?
How many of your wheelin buddies run 30-spline longs?
I've seen the Longs hold do some amazing stuff! But, come on man, 42's? In a Rover? With beadlocks? I'd like to believe it, but I really don't think it's going to hold. Time will tell.....

So a 33" Bogger will act onto an axle the same way a 35" BFG MT would? I don't think so, from experience, not from simple torque math (which I am quite fluent in...)

I'm sure you'll find your Iroks will get more traction in the rocks vs a Bogger......
Let us know how it works out! I hope it holds, I really do!!! That's an eaiser set-up and more attractive than the potato plow D60...

Hmmm,
I'm guessing I would know nothing about this....
Those ain't 33's on that truck.
And before someone shoots off about how we're talking about 42's on Nadim's truck, my point is too many people shoot off their mouth without actually having any firsthand experience.
One more thing, comparing Toyota's with their 500:1 crawl ratios to Rovers with our measly 70:1 (if your lucky) are two totally different things. I have no doubt that Nadim will be fine with the 30-spline Toy conversion (if less than 5.29 gears) and his 42's with an auto and the crappy rover engine. I believe that's the point of this thread.
I figured I'd better add this picture to make my toy experience clear.

hmmm...so the following combo failed:
V6 chevy, manual, and a great amount of gearing with 38" SXs...
versus
V8 Rover (lighter?), Auto (better?), max gearing of +100:1, and 42" IROKs
Well, add to that that I'm trying to get the lightest possible weight, the best possible suspension to assist with traction and eliminate hop and stuff, I think I should be fine...WE'LL SEE...I'll let you know...
Oh, and yeah, I know about IROKs, been running 36"s of them since they came out...All I'm saying is that when an IROK hooks up after some spinning, it has less consequences on an axle than a spinning bogger suddenly hooking up, at similar sizes...
SO WE"LL SEE...cool?
