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 than a selectable or automatic locker.

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

NOTE: We are in the process of adding ABS sensor ports to our V6 differential housings. They will be provided with a freeze plug to block off the port if you do not have ABS. While we are implementing this change, please call before ordering if you need the ABS port version so we can make sure you get the V6 housing with the ABS port.

NOTE: The 4-cylinder & V6 differentials are meant to be run in the stock position (low pinion). Using these differentials in the high pinion position (“flipping”) will cause the pinion bearings to rapidly fail due to oil starvation and void the warranty.

Instructions

Ring and Pinion Break-In Procedure:

New 3rd members require a break-in period to prevent damage from overheating. Any overloading or over-heating during this period can cause the gear oil to break down resulting in ring and pinion failure.

After installation, drive lightly for 20-30 minutes and then allow the differential to cool for at least two hours
Avoid heavy throttle use during the first 500 miles
Do not tow a trailer during the first 500 miles
Change oil after 500 miles to remove any particles suspended in the oil

This may seem unnecessary but it is very easy to damage the differential by loading it before the gear set is completely run in. New ring and pinion gears create excess heat when they are new. This excess heat can damage the heat treatment of the gears.
