If your current setup is struggling to move your build, it’s time to re-gear and feel the difference.

Built For Bigger Tires Heavier Loads And Hard Use

The Yukon YGGM11.5-513 Ring and Pinion Gear Set is designed for trucks running AAM 11.5-inch axles, including GM 2500HD/3500HD models from 2001–2015 and Dodge RAM 2500/3500 trucks from 2003–2016. Featuring a 5.13 ratio, this gear set is ideal for rigs that need low-end torque recovery after upsizing tires or adding weight through towing or accessories. The ring gear measures 11.50 inches in diameter and uses a 12-bolt pattern, paired with a 30-spline pinion shaft for added strength and durability. Yukon’s heat-treated manufacturing process ensures the gears can handle high torque loads, sharp throttle inputs, and rugged driving conditions without premature wear. Precision machining also helps reduce noise and vibration under load. Whether you’re building for work, off-road, or extreme towing, this ratio gives your drivetrain the leverage it needs. It’s a performance-focused upgrade made to match modern torque demands and aggressive driving conditions.
