Good to know

• This is a rebuild service. You send in your front differential. A certified tech troubleshoots it, installs the upgraded bearing kit, sets ring and pinion lash with custom shims and bench load tests the diff before it ships back.
• You are responsible for shipping the diff in. Contact us before you ship. Shipping instructions are linked below.
• The diff comes back with assembly lube only. Fill it with oil before you ride.
