4.175 MLS Head Gasket - .053 SBC LS1 LH

The FEL-PRO 4.175 MLS Head Gasket - .053 SBC LS1 LH is a precision-engineered cylinder head gasket designed specifically for small-block Chevrolet LS-series engine applications, particularly for driver-side installations. This multi-layer steel gasket is essential for creating a reliable seal between the cylinder head and engine block, effectively preventing coolant and combustion leakage while maintaining compression integrity.

Constructed from multi-layer steel (MLS), this gasket offers superior durability and reusability compared to traditional composite gaskets. The 4.175-inch bore diameter aligns perfectly with GM LS-series specifications, while the 0.053-inch compression thickness is designed to maintain the proper combustion chamber volume and compression ratio, optimizing engine performance. FEL-PRO's advanced design incorporates stainless steel facings and elastomer coatings, which enhance resistance to thermal stress and chemical degradation.

This left-hand (driver-side) gasket is crucial for anyone undertaking cylinder head replacement, gasket service, or engine rebuilds on LS1 and compatible LS-series blocks. Professional technicians and engine builders trust FEL-PRO's precision tolerances and consistent quality to minimize the risk of head gasket failure and ensure long-lasting performance in demanding conditions.
