Good quality part with excellent customer support. The only reason I'm giving 4 stars instead of 5 is the delivery took a day longer than expected, but the quality makes up for it.
Appreciate the honest grading on the differential I bought. It runs great, I just wish the install kit was bundled automatically.
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.
