7.5" / 7.625" Differential Ring and Pinion Gear Set 3.73 Ratio

The Richmond GM75373TK is a precision-engineered differential ring and pinion gear set designed for GM 7.5, GM 7.6 IFS, and GM 7.625 axle applications. This kit offers a 3.73 gear ratio, providing an upgrade for improved off-the-line acceleration and throttle response, making it suitable for street performance or mild drag racing. The thick ring gear design ensures compatibility with carriers originally intended for 3.08 or numerically lower ratios, eliminating the need to replace the carrier. Constructed from 8620 steel, this gear set is precision-machined to meet OEM and performance standards, promising quiet operation, long-lasting durability, and consistent performance under load. The specifications include a 10-bolt pattern, 11 pinion teeth, a 41-tooth ring gear, a 1.438-inch pinion shaft diameter, and 27 pinion splines. Installation of this gear kit is considered hard and requires advanced mechanical knowledge, including proper gear pattern setup, torque specifications, and backlash adjustments. A professional installation with the right tools and expertise is highly recommended for optimal gear alignment and reliability. The product comes with a 1-year or 50,000-mile warranty. This specific kit is noted to fit 1993 to 2002 Chevrolet Camaro models with the GM 7.6-Inch IFS and carriers originally geared at 3.08 or lower. It is also listed for applications including 2004-2013 Chevrolet Colorado, 2004-2012 GMC Canyon, 2006-2010 Hummer H3, 2009-2010 Hummer H3T, and 2003-2008 Isuzu Ascender.
