Gearing selection

MNBOY · 11-10-2005, 09:33 AM

I know this has been brought up a bunch, and there are a bunch of neat charts people can link to showing me generic info. I'm looking for feedback from folks that have actual experience here. I have two lockers I am installing in my truck, one with 4.88 gears and one with 5.29. Obviously one needs to be regeared, and I'm trying to figure out which one. These will be in a pickup running 33" tires, the 22RE with a 5 speed, and it will be used as a daily driver, a cross country road trip vehicle, and an offroad truck on easy to hard, but not extreme, trails. I would love to go with crawler gears right away, but I'm almost out of money on this build, so it could be a long time before that happens. So anyone with experience using the tire/engine/tranny combination I mentioned and either of the gearing options, I'd love to hear feedback on the good and bad, or if there will really even be a noticable difference between the two. Thanks.

Hey Greg,

If the truck is gonna see significant pavement time I'd stay with the 4.88's. I was chasing a vibration problem a couple years ago - to eliminate bent rims as the cause I swapped a set of 33's onto the rig. W/ 5.29's and 33's it was geared way, way to low for sustained highway cruzin. I drove the truck about 60 miles prior to putting the 35's back on - not a lot of miles, but enough to know the truck was pretty much not useable at over 65 miles per hour. (as it is now, it's not useable above 70 for any length of time either, but that's a different problem

)

Ya go with 4.88s, as they're already slightly lower (couple %) then what you need (no one makes the exact ratio) so 5.29s would be way too low.

5.29s should be used on 35s and larger.... 4.88s would be good for 33s, especially on daily driver/road trip vehicle

Mark, thanks for the example. And not to piss anyone off, but I'm looking for real world experience: I was set up exactly like you say and this is what it was like.

I've seen enough charts and book quotes. There are a lot of folks that were set up just like that, except they had a 3.4, except the gears were 4.56........
The Runner on 34's with 5.29's seemed about perfect for offroad, but it saw very little highway time, and again the difference in tire size is a difference.
Thanks.

I run 4.88s/ lockright 33s and 22-RE. (just recently went to 35s) I loved the combination. For the crawl gears I went to marlin and got the 4.7 kit. that is perfect for the daily driver and crawler. I drive my rig daily and take it on road trips up to 10 hours away. No problem with power or anything else.

I ran 4.88 on 33s and 35s and even 36s. on my 89 runner with the 3.0.

4.88 is great with 33s, pretty bad with 35s and bad with 36s here in Denver.

5.29 with the 36s is good. I'm sure it would be better with a fresh engine or lower altitude, but my truck is my daily driver 70 miles/day and I use 5th gear on the hghway.
