Description

Everyone has different needs for their truck. One of the most dramatic changes you can make to a vehicle are the rear ring and pinion gears. Whether you are going for aggressive low-end response for performance and towing, looking to make your truck a highway cruiser, or you've made a change to your wheel and tire size, Hurst ring and pinion sets are available to assist with the transformation. They offer gear sets ranging from 3.08 to 4.56 for the GM 12-bolt rear ends to get you exactly where you need to be. Hurst sets feature high-grade steel for strength and durability along with a gear tooth finish that reduces friction and heat for longevity.
