8 1/4 rear end pros and cons

8 1/4 rear end-How much is it good for? torque/horsepower

me-I have noticed that the rear ends in a lot of late model jeeps are similar to the 8 1/4 in my 76 volare road runner (E58) {360}
how much can I throw at it?
I found an 8 1/4 pinion snubber and a package sale of bearings and a sure grip unit on ebay. I want to keep using this rear in my Aspen F body.

drmopar-This is a surprising decent rearend that has been overlooked by most. Just beware when buying the posi, there are two different units. One for 2.41 and higher gears and one for the others. My brother has a 8 1/4 in his 14 second Duster. No issues. I have also seen them in a 12 second Aspen. The guy ran it this way for yrs. without any issue.
He has a 360 making 450 horse with slicks.
The C-clips on the mopar rear end cannot drop out like a chevy unit, so no need to worry about spitting out an axle.
Good Luck.

68440Barry - I have an 8.25 posi in my 74 pickup with a 67 440 and about 400 h.p. So far so good.

yvdz - Keep that 8 1/4, they are strong enough to handle a potent small block. Besides, they are WAY easier to find than a 8 3/4

RBolig - I have a 4.10 geared 8-1/4 in the Dart Sport with a 400 hp small block and a four speed, and it's having no problems.
