Trying to choose between 4.88 and 5.29 gears

My Nitro 4.88s do not whine, 5.29s should not either if installed right. Be sure to use a competent shop.

Nitro also uses Koyo (OEM) bearings in their rebuild kits which are the best ones to get.

 

It has more to do with utilization of 5th/6th gear, which are both ‘overdrive’ gears on a Tundra.

Anything over a 33” tire and you’re gonna use 6th a whole lot less. 35s? Kiss 6th goodbye altogether unless you're pointed downhill. That’s my experience living at altitude doing a lot of mountain trips.

Regarding mileage, even with gears you also have to run a speedometer calibrator. My fuel mileage is 6-8 while off roading, 10-12 in town and 11-14 on the highway. You might get 15 on 37s at 50 MPH on flat ground but no one actually drives like that except your grandpa. 37s are stupid on these trucks IMO unless you do A LOT of off roading.

 

Great thread. I'm finally biting the bullet and regearing my truck. I was torn on 4.88 vs 5.29, but went with 5.29 with an Eaton e-locker for the rear based on this thread. I'm currently on 35's but at least I'll be ready should I go up to 37's in the future.

 

Great thread!

i’m looking to get some gears now and I think I’m gonna go with 529’s and a rear ARB locker.

Any updates?

 

Went with revolution 5.29 gears on a group buy...Love them

 

Damn I can use a group buy on gears

 

what about 20% off Nitro gears?

 

Send link so I know it’s real.

 

PM me and I’ll find out for you.

 

Where can one order Sierra gears?

 

Anybody used 4WP for gear install? Are they good/reliable for the job?

 

I have not used them but they do have a 10% discount and I believe they have a warranty.

 

They did the gears on my blazer and I've had no issues with it.
