Universal Joint 1350WJ Series ISR 1.188 Cap

The DANA-SPICER Universal Joint 1350WJ Series ISR 1.188 Cap is a precision driveline component engineered for heavy-duty drivetrain applications requiring reliable torque transmission and directional articulation. This universal joint cap assembly is designed to accommodate 1.188-inch bearing caps and includes factory retaining clips, making it a complete drop-in replacement for OEM and aftermarket driveshaft systems operating under demanding conditions.

Constructed from steel with a natural finish, this 1350WJ universal joint cap delivers the durability and corrosion resistance required for both on-road and off-road service. The 1.188-inch bearing cap specification is critical for maintaining proper needle roller bearing preload and ensuring smooth operation across variable load conditions. At 1.65 pounds, the component integrates seamlessly into complete driveshaft assemblies without adding unnecessary weight. The included retaining clips simplify installation and eliminate the need for separate fastener sourcing, reducing assembly time and potential fitment errors.

This universal joint cap serves operators of trucks, SUVs, and high-performance vehicles where driveshaft reliability is non-negotiable. Whether used in factory restoration, transmission swap projects, or performance upgrades, the 1350WJ series is engineered to handle the demands of both street and off-road driving. Technicians and drivetrain specialists trust DANA-SPICER components for their engineering precision and proven longevity in production applications.

The 1350WJ designation indicates this joint is rated for light-to-medium torque applications common in mid-size trucks and SUVs. Proper universal joint maintenance—including regular inspection of bearing caps and retaining clips—ensures extended driveshaft service life and prevents vibration and drivetrain noise that signal worn components.
