Trail-Creeper™ Samurai Ring & Pinion Gears are the best of the best. We have spent years of research and development making these R&P gears as strong and durable as possible so that you can feel confident when you drive down the trail.
RING & PINION BREAK-IN PROCEDURE
All new 3rd members require a break-in period to prevent damage from overheating. Any overloading or over-heating during this periods can cause the gear oil to break down resulting in ring & pinion failure.
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 & pinion gears create excess heat when they are new. This excess heat can damage the heat treatment of the gears.
