Quality Differential Parts since 1982!
Until recently, the only available option for Tacoma owners wanting a replacement gearset with a 4.11 ratio has been high-priced Toyota dealer parts. West Coast Differentials offers a much more practical Tacoma 4.11 alternative.
We carry Sierra Gear & Axle quality Toyota Ring and Pinion Gears at reasonable prices. Available in 4.11, 4.56, 4.88 and 5.29, Sierra Gear Ring and Pinion Gearsets are engineered and manufactured for easy setup, quiet operation and long trouble-free operation.

The ProCal Module is an easy way for Jeep Wrangler JK owners to correct the speedometer and shift points when larger tires are installed and gear ratios have been changed.
The Procal Module provides functions for large tire recalibration, axle gear ratio recalibration, tire pressure monitor recalibration, daytime running lamp activation/deactivation, one -touch turn signal activation-deactivation, engine idle speed options and precise steering wheel centering. These functions are available for all JK Wranglers including the new 2012 models. Owners of earlier versions of the ProCal can send their module in for a re-flash, updating software for use with 2012 model JK's.
