8 1/4 rear end pros and cons

The 8.25 has been in production longer than any other Chrysler rear end. It has been used in Jeeps almost since Chrysler acquired Jeep and there is extensive after market support. I rebuilt mine with all new bearings, ring and pinion for less than $250. even upgrading with stronger parts is less than an 8.75.

I have over 50k miles with many hard launches and smokey burn outs on my 8.25.

In general you can buy an 8.25 and rebuild it for a lot less than an 8.75. If aren't going racing with slicks and a torquey big block you can save some money that can be used else where. If you are building a big power big block an 8.75 may not be enough and stepping up to a Dana 60 might make more sense.
