New reproduction 1990-1992 Corvette LT5 engine front cover gasket. Front cover gasket has been modified from the original GM gasket. Width slightly increased to utilize all the available surface area on the front cover and engine block - for increased sealing contact area. Gasket thickness remains the same as the original GM gasket. This enhancement makes the gasket more leak resistant. Made from Pro-Formance/MicroPore, non-asbestos gasket material with a fully cured nitrile butadiene rubber binder, 12~20% compressibility for excellent seal ability and a max temp rating of 550F.
