hey got a ap1 and is planning to buy a ap2 diff. any other parts i need to swap it out? does it bolt right on? would it make a differents? any suggestions?
The carrier end caps are different...that's the only structural difference between the two. A small amount of metal was added, but it does seem to make the ap2 diff stronger. You still won't be able to beat the diff with constant clutch drops, but it should hold up a better than the ap1 diff.
