Most Popular Questions

How do you know if you need the thin or thick ring gear? I currently have a DANA 80, single wheel, disc brake with 4.11 changing to 3.73
View Staff Answer 
Dana 80's that came with factory 4.11's or numerically higher gears will require a thin cut gear to fit the carrier.

3.73 and numerically lower factory Dana 80's will require a thick cut gear.
