I am stepping up to Black Rhino 17” wheels and Yokohama New MTs in 35”. I am heavy fully loaded. Would it be better to do 4.88 or 5.29 I like to drive at and average speed of 70 mph on hwy. comments suggestions???
Concerning 35" tires, all the comments to go with 4.88 are obviously owners with light loads or not towing. I was warned by @gearinstalls.com (when upgrading) that many owners he installed 4.88's in had got back to him wishing they'd gone with the 5.29's. If speed and light loads are all you'll do, 4.88 will probably work. I run 315/75/16 with 5.29's and at 65 mph my tach reads 2750-2800. 70 mph is about 3k. My'94 is fully armored and I tow a squaredrop off road trailer. 5.29's are the better choice for 35's off road for power. About the only negative thing that I've heard about 5.29's is the pinion is at the minimum for strength due to the smaller number of teeth needed for the gear ratio (smaller gear has less "beef" for structural strength). There has been breakage reported in extreme events, so care with your right foot would be advised. If you're getting into your diffs like I was, to install e-lockers, it's the perfect time to do it. But if you're not opening up your diffs, you might consider changing your gearing in your transfer case (center diff) instead. This page on Cruiser Outfitters website is an excellent choice for parts for T/C. You'll need to do some scrolling to get there and I would talk to them for their advice for your best satisfation, if you choose to go that way. Look for the Land Cruiser Transfer Case Low Range Gear Sets section about 2/3rds of the way down.

So I hear what your saying ^ but not sure I agree.

ive been running stock gears at altitude since 2015 on 35’s. Many over the pass trips (11,000ft) towing and not towing, always been able to hold 65mph+ at the toughest parts

now I’m about to put my 4.88’s in because I’ve wanted to for a long time. But if the rig has been fine on 4.10’s hauling its 7k lbs ass around at altitude 4.88’s should be just fine.

I also have the transfer case gear. Which I think is absolutely necessary regardless of your diff gearing. Really gives you best of both worlds.
