Application Notes: High Pinion units should only be used in front axle applications. Use in the rear axle will lead to ring and pinion failure. Spool lockers should only be used in rear applications. Spools will be harder on axles then a selectable or automatic locker.

Note: Follow Ring & Pinion break-in instructions on the Instructions tab.  Failure to do so will void warranty.

Note: V6 Housings do not have an ABS sensor port and are not compatible with the factory ABS system.
