Product Description

The HKS 2301-RT032 Head Gasket is a high-performance, stopper-type multi-layer steel (MLS) gasket engineered specifically for Toyota Supra MK3 models equipped with the 7M-GTE engine from 1986 through 1992. Designed to withstand the extreme pressures and temperatures of high-boost and tuned engines, this gasket delivers superior sealing performance over standard OEM gaskets, helping maintain compression and prevent leaks under demanding driving conditions.

At 2.0 mm thickness with an 86 mm bore, the gasket not only provides robust combustion sealing, but also allows for slight adjustments to dynamic compression ratios for tuning purposes. The stopper-type design uses multiple steel layers and molded stopper rings around the combustion chamber to maximize sealing integrity, making it ideal for enthusiasts pushing their 7M-GTE powered Supra on street or track applications.
