What It Helps Address

• Oil seepage at the main bearing seal area
• Loss of sealing integrity during engine rebuilds
• Replacement needs for worn original sealing components
• Service work on Chevrolet Camaro, Corvette, Impala, and truck engines
• Fitment matching for GM applications that use a one-piece rear main seal style

Installation Notes

Verify engine configuration before installation, since this part is listed for specific 2-piece, lip relocator type applications and select rear-position fitments. Clean all sealing surfaces thoroughly and confirm the seal orientation before assembly. Use the vehicle and engine details to match the application exactly, especially on Chevrolet Camaro, Corvette, and other classic GM platforms.
