Just go to a dealership, get the 4.91 ring and pinion, new pinion bearings, 2 quarts of fluid, and a shim kit.

Is everyone still on stock differential? Wanting to swap gears but was told its risky and could mess up the diff quickly.

I have one for sale if you can't find one. Has a couple thousand miles on it but I will REM polish it so it will be like new if you want it..

To be fair, I drive it hard, pretty much all the time. And it failed after a day at a really tight track. 5 30min sessions on a track that has lots of sharp turns and even a u turn. Would it have died had I not changed the ring? We'll never know. |

I posted somewhere all the part numbers for carrier bearings and races, pinion bearings and races, seals, and crush washer. *EDIT* - http://www.camaro5.com/forums/showthread.php?t=419917 It's not risky. Do the swap, break them in for 500 miles, drain and fill fluid, enjoy.

If your going to do it and drag...add a LPW diff cover(https://www.lpwracing.com/Ultra_IRS/Ultra_IRS.html...cheap insurance IMHO...most failures due to bearing cap walk leading to the ring pulling away from the pinion until boom...
