Ring & Pinion Dana 60 5.38 Ratio

The Ring & Pinion Dana 60 5.38 Ratio is a precision gear set engineered for high-performance differentials in heavy-duty trucks, off-road vehicles, and competition rigs. This gear package is designed for builders and enthusiasts who demand superior crawling ability, towing capacity, and driveline reliability under extreme load conditions. The 5.38 ratio provides aggressive low-end gearing ideal for rock crawling, steep hill climbs, and maximum wheel torque delivery in demanding terrain.

This Dana 60 ring and pinion set features a 9.75-inch ring gear diameter with a 29-spline pinion shaft, delivering optimal strength and mesh contact for sustained high-torque applications. The 5.38 gear ratio multiplies engine torque by reducing output shaft speed, generating exceptional pulling power at lower RPMs—critical for loaded trail driving and recovery situations. Manufactured to tight tolerances, this kit ensures smooth engagement, minimal backlash, and extended service life when properly installed and setup by experienced technicians.

Ideal for owners upgrading Dana 60 rear or front differentials in Ford Super Duty, Dodge Ram, Chevrolet Silverado, and Jeep platforms, this ring and pinion ratio suits those prioritizing low-speed control and maximum mechanical advantage over highway cruising efficiency. Installation requires professional differential setup, including proper pinion depth adjustment, ring gear backlash confirmation, and bearing preload. Verify Dana 60 housing compatibility—particularly spline count and carrier type—before purchase to ensure correct fit and function.
