This precision gasket features a .040" compressed thickness and is designed for a 3.860" cylinder bore diameter.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme conditions

Good product

Obtaining the ONE needed OEM tire for my mom's 4-door race-car, Mercedes's sweet S63 AMG, seemed like a progressively daunting task upon attempting to locate one anywhere that could be in hand in less than 2 weeks. I'd prepared myself for the potential expense, scarcity, and delay given the status quo of the delivery of just about anything these days but found this tire and THM to be like a needle in a haystack. The process was seamless, EXTREMELY economically advantageous, and SPEEDY. ($9.99 got this obscure tire to my front door in 2 business days, period. It was awesome; made me out to be the enterprising, resourceful son I hope to actuality be one of these days, ha. Great experience.

Super

Delivery was delayed two days from original estimate. Otherwise product was what was ordered. Happy with product.
