LS Cam Thrust Plate w/O-Ring Gasket

The LS Cam Thrust Plate with O-Ring Gasket from Straub Technologies is a precision engine component engineered to control camshaft endplay and maintain proper valve timing geometry in LS-platform engines. As an experienced mechanic, you'll recognize this as a critical wear component that prevents camshaft walk—a condition that degrades performance and can lead to catastrophic valve train failure if left unchecked. Whether you're rebuilding a stock 5.3L, tuning a 6.2L performance build, or restoring a LS3 powerplant, this thrust plate ensures your camshaft remains seated and your valve timing stays accurate under all load conditions.

This thrust plate mounts on the front of the camshaft and constrains axial movement by bearing against the cylinder block's cam pocket. The integrated O-ring gasket design eliminates the need for separate RTV or traditional gasket materials, reducing assembly time and improving seal integrity across multiple thermal cycles. Machined from durable materials and engineered to OEM tolerances, the Straub Technologies unit resists wear from continuous contact with the block while maintaining a precise, repeatable gap—critical for engines running aggressive cam profiles or high RPM applications. The compact 6.1 x 0.3 x 8.15-inch form factor integrates seamlessly into any LS family engine, from carbureted small-blocks to modern direct-injection variants.

Performance builders, engine shop professionals, and serious LS enthusiasts benefit most from this OEM-quality replacement, especially when addressing worn factory thrust plates or building new long-block assemblies from the ground up. Installation is straightforward during any complete engine teardown—simply position the O-ring gasket, seat the plate, and install the fastener, ensuring your camshaft won't drift forward during startup or high-load operation. Compatible with all LS variants (LS1, LS2, LS3, LS6, LS7, LS9, LT engines, and truck-based LS motors), this thrust plate is a non-negotiable upgrade for any serious rebuild where valve train precision and durability matter.
