Heavy-Duty Drivetrain Engineering: Axle Solutions for Your Jeep Wrangler YJ.

The combination of rigid solid axles and a manual transfer case is what defines the legendary off-road heritage of the Jeep Wrangler YJ. Throughout the 1987-1995 production run, these axle assemblies and driveshafts are subjected to extreme torque loads on and off the highway. Failing wheel bearings, howling differentials, leaking oil seals, or severe driveline vibrations after installing a leaf-spring lift kit are common maintenance milestones. Our online inventory features targeted replacement parts and heavy-duty upgrades to successfully rebuild your classic’s drivetrain or reinforce it for extreme trail abuse.

We strictly rely on the unmatched factory standards of Dana Spicer to supply ring & pinion sets, master carrier rebuild kits, Trac-Lok shim sets, and heavy-duty replacement axle shafts. For extreme trail conditions, upgrade your build with high-strength U-joints and outer axle tube seals from Alloy USA (Omix).
