    More Power. Give your cherished Silverado the upgrade in power that it deserves by installing Richmond's 3.90 Rear Ring Gear and Pinion Set with an 8.5"/8.6" ring gear diameter in place of the existing rear ring and pinion. The quality set is made to deliver an improved everyday driving experience by upping your truck's performance level. Gain more torque for your transmission and smoother handling now that you've got that lift and larger tires. The improved differential gear ratio of 3.90 gives you more fun in the driver's seat.

    Built to Last. Richmond's advanced, thoughtful design, and comprehensive engineering make for a durable and long-lasting street gear differential ring and pinion set. The 10-bolt set is constructed from first-run 8620 steel rather than potentially weaker recycled materials and has undergone a computer-controlled heat treatment for extra strength. A two-year/100,000-mile warranty protection on materials and workmanship comes with the rear ring and pinion set, giving you confidence in its longevity.

    Bolt Installation. The Richmond set features a rear ring gear and pinion gear. These parts bolt-on in place of the existing rear ring and pinion. After removing the current gears, prep the mounting surface as per the included installation instructions before attaching the new set to ensure a precise fit.

    Application. The 3.90 Rear Ring Gear and Pinion Set from Richmond fits 2007 to 2013 Chevy Silverado truck models with a 30 spline count and an 8.5"/8.6" ring gear diameter.

    Technical Note. Installation costs will vary, but a good rule of thumb is between $250 and $300. Be sure to work with a reliable shop that you trust for installations.

        What front ring and pinion is required for a 4x4 Silverado? Thanks

        • I apologize, we don't currently carry the 3.90 ring and pinion gears for the front.
