This Mr. Gasket Rear Main Seal is made from Viton® Rubber. This style of rubber can handle high temperature like silicone rubber, but with superior abrasion resistance. Its durability and it's double, offset lip seal design make it recommended for applications that have high engine vacuum, like racing engines that utilize external vacuum pumps for crankcase evacuation.

Features:

  • Repairs That Leaky Rear Main Sail
  • Viton® Rubber Offers Both Abrasion Resistance & High Temperature Tolerance
  • Upgrade for Rope Seal Equipped Cars or Silicone Rubber Main Seals
