Rubber Seal - LS Timing Cover

The Rubber Seal - LS Timing Cover from Chevrolet Performance is an essential OEM-quality gasket designed for LS-series engines across a wide range of GM applications. This timing cover seal prevents oil seepage at the front of the engine block, protecting internal components from contamination and maintaining proper lubrication flow. Whether you're rebuilding a classic LS engine, performing routine maintenance, or upgrading your vehicle's powertrain, this genuine rubber seal ensures factory-spec fitment and durability.

Manufactured from high-grade elastomer compound, this timing cover seal is engineered to withstand the thermal cycling and oil exposure inherent to high-performance LS engines operating at elevated temperatures and pressures. The rubber formulation resists degradation from synthetic and conventional oils alike, maintaining its sealing integrity across thousands of miles. Precision-molded dimensions (5.3 x 0.75 x 5.4 inches) ensure a perfect fit against the timing cover mounting surface, eliminating the risk of leaks that can compromise bearing lubrication and engine cleanliness.

Mechanics and engine builders trust Chevrolet Performance seals for LS block work because they eliminate guesswork during timing cover installation—critical when reassembling after valve cover work, cam swap, or front-end service. This individual seal replaces the factory original, making it ideal for single-engine jobs or inventory restocking. Compatible with all LS variants (LS1, LS2, LS3, LS6, LS7, LS9, and LT-series adaptations), it delivers confidence that your oil containment meets GM engineering standards.
