Manufactured for use in compatible GM 10-bolt applications, this Revolution Gear & Axle set is intended to work with the original-style differential architecture while offering a dependable replacement for damaged or worn ring and pinion components.

Proper setup requires careful attention to pinion depth, backlash, bearing preload, gear marking pattern, lubrication, and break-in procedures. Installation should be performed by a qualified technician using the correct tools and service specifications for the application.
