Upgrading 8.25....

AZ DESERT RAT · Feb 20, 2005

I'm going to be changing my 27 spline 8.25 to a 29 spline with ARB and 456's. My question is what type of install kits will I need to replace all the seals and bearings? There are master kits but I'm not sure if they have all the proper bearings and seals...the reason I ask is there are pinion kits,bearing kits etc. I wasnt sure if all the stuff in the smaller kits is also included in the Master install kit? I checked out Raw Brown and Randys..anybody recommend someone else?

The master kit has everything. Here's a pic of the master kit for my 8.25 which is being installed tomorrow.

Got it from Superior free when I bought my gears. Make sure you get quality bearings (i.e. Timkin).

Just get a 29-spline master install kit and you'll have everything you need, except for a Chrysler adjustment tool. If you're buying a new ARB they usually come with one carrier bearing installed, but that's to prevent the end user from damaging that part. As for bearings if you get Sierra/Superior/Spicer/Yukon they use Timken bearings, so you'll be all set.

If you're going to the trouble of swapping to Phord why not just do a 9"?
