Early Bronco Dana 44 Gold Axle U-Joints: 4340 Forged

Upgrade your 1971-77 Ford Bronco with these Dana 44 Gold Axle U-Joints, designed for use with upgraded chromoly axles (not compatible with stock axles). Made from 4340 forged material, these U-joints offer a significant strength boost—about 25% more than OEM joints—and an even greater 72% strength increase thanks to their larger trunnion size. They are engineered to withstand the rigors of extreme off-roading, eliminating common issues like needle-bearing disintegration and lock-up.

These U-joints feature a unique design that eliminates the need for bearings or bushings, preventing galling from metal-to-metal contact. Each cap and trunnion has its own 300 PSI-pressurized grease reservoir, keeping out water and debris during harsh conditions like water crossings or deep mud. The high-temp copper and graphite grease withstands extreme loads of up to 200,000 psi and temperatures up to 2000°F, ensuring reliable performance under the most demanding conditions.
