Universal Joint 1310WJ Series ISR 1.188 Cap

The DANA-SPICER Universal Joint 1310WJ Series ISR 1.188 Cap is a precision engineered driveline component built to handle the demands of heavy-duty vehicles and equipment. This universal joint operates as a critical connecting element in drivetrain systems, transmitting torque between misaligned shafts while accommodating angular and axial movement. The 1310WJ series is commonly found in mid-size trucks, SUVs, and industrial applications where reliability under load is non-negotiable.

The 1.188-inch bearing cap specification indicates the cross-section dimension of the bearing journals and trunnion design. This measurement is critical to the joint's load-carrying capacity and rotational balance. Manufactured from steel in natural finish, the joint provides corrosion resistance suitable for most operating environments. The included clips secure the bearing caps in place, eliminating the need for separate fastening hardware. At 1.33 lbs, this component is a direct replacement unit designed to bolt into OEM mounting locations without modification.

This universal joint is essential for fleet maintenance, off-road recovery operations, and drivetrain restoration projects. Technicians restoring classic trucks, maintaining commercial vehicle fleets, or rebuilding driveshafts rely on Dana-Spicer components for OEM-specification performance. Whether replacing a worn joint due to bearing wear or servicing a complete driveline assembly, the 1310WJ series delivers the precision fit and durability expected from Dana's engineering standards. The natural steel finish and included fasteners simplify installation, allowing technicians to complete repairs without sourcing additional hardware.

Dana-Spicer universal joints are industry-standard components across light-duty and medium-duty driveline applications. The 1310WJ series occupies the mid-capacity range, making it suitable for vehicles that experience moderate to heavy towing or payload stress. Understanding the bearing cap size ensures proper fit when sourcing replacement joints for your specific driveshaft assembly.
