2K11 U-Joint Assy. H.D. Aluminum w/Glad Cross

The 2K11 U-Joint Assy. H.D. Aluminum w/Glad Cross (MPN: SRC-2355) from Diversified Machine is a heavy-duty driveshaft component engineered for vehicles requiring maximum strength and precision under demanding conditions. U-joints are critical transfer points between your transmission and rear axle, transmitting engine torque while accommodating suspension articulation and drivetrain angles. This assembly is built for serious off-road, towing, and high-performance applications where standard OEM joints fall short of reliability demands.

Constructed from high-density aluminum, this u-joint assembly reduces rotational mass compared to traditional steel designs, improving throttle response and reducing driveline vibration. The Glad cross design (also called Spicer or precision-machined cross) uses hardened needle bearings seated in each arm, delivering smooth power transfer and longer service intervals between maintenance cycles. Aluminum construction also enhances corrosion resistance in wet or salt-exposed environments, critical for trucks and 4x4s operating in challenging terrain. The lightweight profile helps minimize parasitic losses while maintaining structural rigidity under peak torque loads typical of lifted trucks, diesel engines, and performance builds.

Mechanics and enthusiasts building 2011-era vehicles with aftermarket driveshafts, lifted suspensions, or high-output engines rely on this assembly to eliminate clunking, vibration, and premature wear at the driveline interface. Installation requires proper driveshaft balancing and alignment to maximize bearing life; most shops recommend upgrading both front and rear u-joints simultaneously for consistency. The compact 6.75 x 5.85 x 8.15-inch footprint and 4.44-pound weight make handling straightforward during installation. Check your specific vehicle's driveshaft diameter and yoke configuration before ordering to ensure proper fitment with existing components.
