Street Hydraulic Bearing GM 1.375 Collar

The Street Hydraulic Bearing GM 1.375 Collar from RAM CLUTCH is a precision component engineered for General Motors applications requiring reliable hydraulic bearing support in manual transmission systems. This collar serves as a critical interface between your clutch mechanism and the transmission input shaft, handling the demands of both street and performance driving. Whether you're rebuilding a classic Chevy, Pontiac, or Oldsmobile clutch assembly or upgrading an existing system, this 1.375-inch collar provides the exact dimensional fit and load capacity your drivetrain needs.

Manufactured with precision tolerances, the Street Hydraulic Bearing GM 1.375 Collar is designed to work seamlessly with hydraulic release bearing systems common in GM vehicles. The 1.375-inch bore diameter is engineered to maintain consistent pilot shaft alignment, reducing vibration and extending clutch disc life under sustained driving conditions. RAM CLUTCH's quality construction ensures this collar withstands repeated engagement cycles and maintains concentricity even during aggressive downshifts or high-load scenarios typical of street performance driving.

This bearing collar is ideal for mechanics and enthusiasts restoring or upgrading GM manual transmission clutch systems, particularly those transitioning to hydraulic-assisted release mechanisms. The compact 5.15 x 4.35 x 5.25-inch profile fits standard GM bell housings without modification, and the 1.37-pound weight keeps drivetrain mass minimal. Proper installation requires correct orientation with the transmission input shaft to ensure smooth clutch disengagement and prevent premature bearing wear. Always verify compatibility with your specific vehicle year and transmission model before purchase.
