Universal U-Joint Protector / Keeper

The WEHRS MACHINE Universal U-Joint Protector Keeper (WM14) is a precision-engineered plastic cap keeper designed to secure and protect u-joint caps during assembly, storage, and operation. This adjustable universal-fit component prevents accidental cap loss or damage on driveline systems where u-joint retention is critical—a common concern in high-vibration automotive, off-road, and performance driving environments.

The keeper's adjustable design accommodates a wide range of u-joint cap diameters, eliminating the need for multiple size-specific tools or replacement components. The black plastic construction provides durability without adding weight or interfering with driveline clearance. At just 0.1 lbs and compact 3.1 x 1.5 x 4.65-inch dimensions, the WM14 integrates seamlessly into engine bays and chassis without modification. The plastic material resists corrosion from road salt and moisture—a particular advantage for vehicles operated in harsh environments or stored outdoors.

This universal keeper is favored by engine builders, transmission shops, and off-road enthusiasts who need reliable u-joint cap retention during installation, testing, and long-term operation. Whether assembling a high-performance driveline, rebuilding a vintage transmission, or maintaining fleet vehicles, the WM14 prevents the frustration and potential safety hazard of loose or missing u-joint caps. WEHRS MACHINE's reputation for precision driveline components ensures this keeper meets the standards of serious automotive professionals.
