Features, Description, Q&A, Specs & Installation
Designed for the Daily Driver. Daily street driving can be quite harsh with modern loads and shorten the service life of your stock ring gear and pinion. The 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit with 3.42 gear ratio is designed as a replacement for the stock ring and gear. The gears are made to OE factory specifications for perfect fit and feature higher heat tolerance, durability, and runs quieter than stock.
High-Quality Gears. The G2 Rear Ring Gears and Pinions are made from forged 8620 steel which is then heat-treated for added durability. The precision-machined ring gears and pinions are lapped to ensure a smooth finish that reduces friction and road noise.
Professional Installation Recommended. Installing the ring gear and pinion requires a high-level of expertise and specialist equipment. G2 recommends that installation is performed by a reputable professional mechanic.
Includes 10-Year Limited Warranty. G2 warrants that the 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit is free of defects in workmanship and materials. Exclusions will apply.
Application. The G2 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit with 3.42 gear ratio is designed to fit 2007 to 2018 GMC Sierra 1500 models.
