Main Bearing Gasket Set GM LS 1997-2016

The Main Bearing Gasket Set GM LS 1997-2016 from MAHLE ORIGINAL is the comprehensive gasket and seal kit every LS engine rebuild demands. Whether you're performing a full bottom-end refresh on a Gen III or Gen IV LS platform—whether that's in a Corvette, truck, or engine swap application—this kit delivers OEM-specification sealing across all critical bearing surfaces. The rear main seal and timing cover gasket are included, eliminating the need for multiple purchases and ensuring compatibility across the entire LS family.

This bearing gasket set is engineered with MAHLE's proven rubber composition to withstand the extreme pressures and thermal cycling inherent in modern LS performance builds. Each gasket is precision-cut to OEM dimensions, ensuring zero leakage at bearing journals where pressurized oil feeds the entire drivetrain. The included rear main seal specifically addresses the LS architecture, sealing the crankshaft's aft flange against the block with no room for seepage. The timing cover gasket completes the upper-front seal package, preventing oil weeping that would otherwise contaminate spark plug wells and accessory belts.

Mechanics and enthusiasts rebuilding LS engines from 1997 through 2016 will find this kit indispensable for any major disassembly—whether a crank polish, bearing clearance service, or full engine refresh. Installation occurs during block preparation; proper torque sequence and gasket surface cleanliness are critical to longevity. This MAHLE ORIGINAL kit is the factory-trusted solution, backed by the durability standards that LS platform builders have relied on for two decades of high-performance and stock-stroke applications.
