Why Choose Genuine Honda 91271-HC4-004?

This oil seal is a genuine Honda OEM part, meaning it is identical to the component originally mounted at the factory . Non-genuine or aftermarket seals risk:

  • Incorrect dimensional tolerances – leading to leaks or seal failure

  • Sub-standard rubber compounds – premature hardening and cracking

  • Inadequate lip pressure – oil bypass and component contamination

  • Recurring labour costs – repeated replacement and downtime

This genuine Honda seal is engineered to provide perfect fitment and long-lasting performance in your ATV's engine, transmission, or differential housing .


Genuine OEM Advantage:

Honda genuine parts are the only components engineered and tested to meet all factory standards for safety, performance, and reliability. Trust the original.

Genuine Honda OEM parts are precision-engineered to maintain the performance, reliability, and value of your powersports vehicle.
