Excellent quality! The engine has been running smoothly for months now. Very impressed with State Auto Parts and would recommend to anyone.

Engine performs fine once installed, but the freight carrier rescheduled twice and the harness clips needed cleanup. Worth it for the price if you can tolerate a little extra prep.

Diff runs fine but the seals looked aged and the housing paint was flaking. Budget friendly purchase, just expect to refresh a few wear items yourself.
