Description
Off-Road Essential. Lifting your truck and going for taller wheels make for a fun ride on rocky trails. Compensate the loss of fuel economy with the right gear ratio. Check out the Motive Performance 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit with 5.38 gears. This gear ratio is designed for high performance, low-end torque applications. Conquer rock walls, haul and tow heavier loads with these short gears. Get better control of your truck at low speeds and minimize the loss of fuel economy on highways.
Tough Outdoor Adventure Gears. When you’re working your truck to its limits, you better have tougher gears that can handle the extra load. Fortunately, Motive Performance 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit is built for heavy-duty use and abuse. The short gears are forged from 8620-grade triple alloy steel. Each gear is heat-treated and machined to precisely follow OEM specifications. This ensures proper clearances, backlash, and bearing preloads are achieved for the optimal gear rotation and performance.
Speedometer Recalibration After Installation. Whether you’re upgrading or downgrading your gear ratios, any change would affect speedometer readings. So before you drive your truck on the highway, remember to retune your truck’s computer to update the speed measurements.
Mechanical Skills Required for Installation. It’s never an easy job to modify your ring and pinion gears. Make sure you leave the installation of Motive Performance Rear Ring Gear and Pinion Kit to professional mechanics who know what they are doing. The use of specialized tools and equipment will be needed for a successful installation.

The warranty includes manufacturing defects from materials and workmanship. Exclusions may apply. Please check with Motive for the full details.
Technical Note. Chevy Silverado 4WD models need matching or close to identical gear ratios to work properly. Driving on 4WD mode with mismatching front and rear gear ratios will result in damages to drivetrain parts.
