American Gear - La Habra California

Differentials are typically in the rear of the vehicle and reduce the RPM of the engine to the wheels. Typically on a rear-wheel drive car or truck, the drive shaft carries the power from engine to the differential.   The differential, through a mechanism of gears, distributes the power to the wheels via axles. 

We specialize in differentials.   We can change your gear ratios for speed and off-road performance.
