A rear axle is much more than a housing and differential. Modern off-road vehicles demand stronger brakes, improved wheel-end systems, rear steering capability, and upgraded axle components that can withstand large tires, high horsepower, and extreme terrain. Our Rear End Kits collection brings together complete rear axle upgrade systems designed for rock crawlers, rock bouncers, Ultra4 cars, trail rigs, and custom chassis builds.
This collection includes rear steer systems, rear steer knuckle kits, unit bearing conversions, brake upgrade kits, bearing adapter systems, axle rebuild components, and complete wheel-end upgrades for GM 14-Bolt and Dana 60-based rear axle applications. These systems are engineered to improve serviceability, reduce maintenance, increase braking performance, and provide the steering control required for advanced off-road vehicles.
Whether you're converting a traditional rear axle to rear steer, upgrading from factory hubs to unit bearings, installing larger brakes, or rebuilding a competition-ready rear axle, these kits provide proven solutions trusted by off-road racers and builders across the country.
