Universal Joint 1485WJ Series ISR 1.375 Cap

The Dana-Spicer Universal Joint 1485WJ Series ISR 1.375 Cap is a heavy-duty driveshaft component engineered for demanding powertrain applications where precise torque transmission and rotational flexibility are critical. This 1.375-inch bearing cap universal joint is manufactured from steel in a natural finish and includes integrated clips for secure assembly, making it the go-to replacement for fleet maintenance, off-road recovery operations, and commercial vehicle servicing where reliability directly impacts operational uptime.

The 1485WJ series represents Dana-Spicer's proven industrial-grade design, offering the angular flexibility and load capacity required in multi-speed transmissions and transfer case applications. The 1.375-inch bearing cap dimension ensures compatibility with specific driveshaft assemblies and cross-reference applications where fitment is non-negotiable. Steel construction delivers the fatigue resistance and dimensional stability necessary for vehicles operating under sustained load, towing, or repeated shock loads common in commercial or off-road duty. The included clips simplify installation and ensure the bearing cap remains secure during operation, eliminating the potential for gradual loosening under vibration.

This universal joint component is essential for technicians and fleet operators who maintain medium-duty trucks, commercial vehicles, or specialized off-road equipment where Dana driveshaft assemblies are standard. Whether replacing a worn component during routine transmission service or rebuilding a driveshaft after high-impact off-road use, the 1485WJ Series ISR delivers OEM-equivalent performance and fitment. Proper universal joint maintenance prevents cascading driveline failures that can strand vehicles in remote locations or compromise safety during towing operations.

Dana-Spicer has maintained leadership in driveline components for heavy commercial and specialty vehicles for decades. The 1485WJ series is recognized by fleet service managers and independent shops as a core component for maintaining compatibility with existing Dana driveshaft systems across multiple vehicle platforms and model years.
