This premium Harley EVO Big Twin gasket set features a comprehensive selection of gaskets, each crafted from the finest materials suited for its specific application.

Complementing these are steel Viton®-coated base gaskets, offering superior resistance to oil, fuel, and coolants, ensuring a long-lasting, leak-free seal. Blue Viton valve stem seals further enhance performance by minimizing oil consumption and maintaining valve train efficiency. For the exhaust system, Aluminum Foam Material (AFM) race-style exhaust gaskets provide excellent heat resistance and a reliable seal. With a precise thickness of 1.02 mm (0.040"), every component in this motorcycle engine gasket kit is engineered for a perfect fit and optimal function, making it an essential upgrade for serious riders and mechanics.
