axle sizes gear ratios and tire options

[jimmy94]

okay, according to my findings my 94 sr5 v6 with a 4speed auto, that came with stock 31s, should have an 8 inch rear diff with 4.88 gears. does this sound like a legit finding and is there anyway i can findout myself?

also if i do infact have 4.88s should i be able to run 33s without to much bogging down or causing trans or diff problems? planning on adding a diff locker as well. any suggestions for what lockers serve best for a dd and ocational trail rig, as well as slippery northern ohio winters? thanks!

oh yeah and would it be better to put lockers in the front diff or rear? im looking for manual hubs if any of you guys have an extra set.

4.88 sounds right for the runners that came stock with 31" tires. The rear is an 8" and the front is 7.5" for IFS (also 8" for solid front axle).

You will really want a selectable locker like the ARB or Toyota E-Locker for a DD on the slippery stuff.

This will help you read your vin tag:

So if you have 4.88s, it should say G144

Dont lock the front if you plan on driving on snowy roads. In reality, lockers on snowy roads will cause less traction (unless your stuck) But for simply going down the road, when one wheels starts to slip, the other will hold it straight (to some degree) but when both slip, thats when you spin out (or drift, haha) Also there are MANY people who run lockers through the winter with no problem, so I wouldant really worry about. Youll just have to get used to drving with it, thats all. And with that, I would recommend a aussie or spartan locker. Budget friendly and super reliable. Or if you feel like spending some money, get an ARB or E locker as turbo suggested.

yes, that would be correct

also if i do infact have 4.88s should i be able to run 33s without to much bogging down or causing trans or diff problems? planning on adding a diff locker as well. any suggestions for what lockers serve best for a dd and ocational trail rig, as well as slippery northern ohio winters? thanks!

yes on the 33's. a locker can cause unexpected quirky handling in slippery conditions, rather than helping. if you lock the rear expect the unexpected driving on road in snow/ice.

thanks for the link hyde802! very helpfull and i do have the g144 code so yay 4.88s! thanks for the locker info too guys very much appriciated. so if i understand i can buy a locker, more expensive though, that i can change from the cab from locked to unlocked in the rear for slippery driving and i can lock it if i get stuck?

Yes. The ARB locker uses compressed air to engage/disengage, the E-locker uses 12v. There's pros and cons to each.

Yes. The selectable lockers are going to be more expensive but they do have the benefit of being able to lock them in or out from the drivers seat. The ARB air lockers are very popular mainly because they are widely available, easy to install, stronger carrier than stock and you get to have a nifty air compressor on board for inflating tires etc...

The Toyota E locker is a cheaper alternative if you get one used but you are going to have to modify your axle housing and either deal with the electronics to get it to work or go with the cable mod to engage/disengage the locker. There are quite a few threads on Yotatech and Pirate that detail this install.
