Ring and pinion gears are the foundation of every differential, determining how engine power is transferred to the tires and directly affecting acceleration, crawl ratio, towing performance, highway RPM, and overall vehicle drivability. This collection includes ring and pinion gear sets for Dana, Ford, GM, Chrysler, Jeep, and heavy-duty truck axles, including popular platforms such as Dana 44, Dana 60, Dana 70, Dana 80, GM 14-Bolt, Ford 8.8, Ford 9", Ford 10.25, Ford 10.5, and GM IFS differentials. Whether you're compensating for larger tires, increasing low-speed torque, restoring a worn differential, or building a competition drivetrain, selecting the proper gear ratio is one of the most important decisions in any axle build.
Available in multiple gear ratios, standard rotation, reverse rotation, thick gear, and thin gear configurations, these ring and pinion sets are designed to meet the demands of rock crawlers, rock bouncers, Ultra4 race cars, trail rigs, overland vehicles, tow rigs, drag cars, and heavy-duty work trucks. Proper differential setup is critical for performance and longevity, requiring correct pinion depth, backlash, preload, and gear tooth contact patterns. Whether you're building a dedicated off-road axle or upgrading a daily-driven truck, these precision-machined gear sets provide the strength, durability, and reliability needed to handle increased loads, oversized tires, and demanding driving conditions.
