Tool Transmission Lookup

C&R Racing offers a select line of Motive ring and pinion gears for Chevy 12-bolt and Ford 9 in. rear-ends. C&R Racing treats these gears through a process known as "REM." REM treatment is a surface applicator that reduces friction, resulting in more horsepower. This process makes the ring and pinion gears stronger, quieter, and cooler.
