Product Details

The Cometic C5680 is a premium rear main seal designed for Chevrolet Gen-1 90-degree V6 and Gen-1 Small Block V8 engines. This two-piece seal configuration provides reliable protection against oil leaks at the crankshaft's rear main journal.

Key Features:

  • High-performance Viton rubber construction for superior heat and chemical resistance
  • Two-piece design for proper installation and sealing
  • Direct replacement for worn or leaking OEM rear main seals
  • Compatible with Chevrolet Gen-1 90-degree V6 engines
  • Fits Gen-1 Small Block V8 engines (traditional 2-piece rear main seal applications)
  • Precision-manufactured to OEM specifications for exact fitment

Cometic Gaskets manufactures each seal using premium Viton material, which offers exceptional resistance to high temperatures, engine oils, and transmission fluids. This ensures long-lasting performance and reliable sealing in demanding engine environments. The two-piece configuration is designed for traditional Chevrolet applications that use rope-style or split rear main seals.
