Ring gears

Correct me if this statement is wrong

the gears for a Sterling 10.50 will work in our Sterling 10.25's

I ask cause I think my 75 has 4.10's in it do to the vin plate, and I am going to check, anyways if I do, I need to put gears in my sterling (Its 3.55) also anyone got a LSD or something they would sell me cheap? Cause I got a UNLIMITED (You heard me right) Unlimited slip diff. Anyways thanks guys. Also if I put 4.11 gears in it, would that matter? I dont think .01 would hurt but you never know.

Thanks.

IIRC, you need different bearings for the pinion.
The 10.5 has smaller pinion shaft than the gen 2 10.25.

If you can get a pinion that matches the gen 2 10.25 and will mate up with the 10.5 ring gear, that would be mint.

I believe you have to swap carriers too. I think you can swap carriers and not swap gears as well. To much to remember. haha.

The 10.5 carrier has 3 spiders, which is a lot better if you are running tires over 35 inches.
37 inch tires really tear up the 10.25's spiders.

The truck will tow and sled pull a little, also I plan on running a 35. The truck is originall a 4.10 truck so I will kep it that way, just to kind of match the vin.
