    Save Up on Gas. If you’re using your Silverado for daily driving, you’re better off with taller or lower gear numerical ratios. Check out the Motive Performance 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit if you’re thinking about replacing your old gears. This ring gear and pinion set has a 2.73 axle ratio, which makes it perfect for highway driving and other street applications. You get higher top speeds at lower RPMs on the highway. Best of all, you get better fuel economy.

    Motive’s Performance Quality Gears. Motive draws on their years of racetrack experience to design and engineer top quality gears. As such, the Motive Performance Rear Ring Gear and Pinion Kit are manufactured using only premium materials and the latest machining technology. Motive Performance Gears are forged from first-run 8620-grade steel. The triple alloy steel features a stronger core that delivers increased durability and performance compared to stock. It’s refined to OEM specifications to ensure exact fit with enough clearances and backlash for optimal performance.

    Recalibration After Installation. If you are changing gear ratios, remember to update your onboard computer. Speedometer readings are affected by gear ratios and tire diameters so after installation, reprogram your vehicle using a tuner or recalibration device.

    Professional Installation Required. The installation of your Motive Performance Rear Ring Gear and Pinion Kit is not an easy task. Specialized tools and equipment will be required to do the job properly. It’s highly recommended that you take your truck to your trusted shop for the installation to prevent issues and void warranties.

    2-Year/100,000-Mile Warranty. Motive is so confident on their Motive Performance Rear Ring Gear and Pinion Kit that they offer a 2-year or 100,000-mile warranty to their customers. The warranty covers material and workmanship defects but excludes incidental damages. Please go visit the Motive website to learn more about their warranty policy.
