go for a dana 60 if you can afford it.
the 9.25 is a stout axle that can handle decent HP or decent sized tires. i dont know what year ur truck is, but it is probably old enough that the rear could benifit from a rebuild. if u can find a 5lug d60, that would be a nice upgrade.

The 9 1/4 should be able to handle it, I agree. The big IF is that it has to be in good shape to begin with. I'd stick with the 9.25 but do a rebuild. Is it a limited slip? I've done a burn out or two on my RC and never had a problem, but you gotta use some judgement on the burn outs too, they are hard on all components and anything can be spun too fast.

THANX FOLKS FOR THE REPLIES. its a 1990 d-150 and it is a limited slip diff. heh the old truck has 300,000 (well 289,000) so it's time for some thing to break . So the 9.25 is fine and a rebuild would be the best route ,well lest in expensive.OK now what diff would u guys recommend ?AUBURN , is the diff. thats in there if im not mistaken . Should i go with a different brand or stay with the stock . like i say its ganna be a driver , mess around ride. thanx again folks
My suggestion is to go stock whenever possible.

Auburn s are a top dog manufacturer. but, if you wanna save a couple of $$$, you can just replace the clutch pack in it. that s if you feel like messing with it.
