LS Cam Thrust Plate w/Oil Retention Grooves

The LS Cam Thrust Plate with Oil Retention Grooves is an essential internal engine component designed for LS-platform engine builders and enthusiasts who demand precision in their builds. This thrust plate serves a critical function: it controls camshaft end-play while preventing unwanted cam movement that can cause catastrophic valve train failure. Whether you're assembling a stock rebuild, a mild street engine, or a high-horsepower performance platform, proper cam thrust plate selection is non-negotiable for reliable operation and longevity.

Manufactured by Straub Technologies, this thrust plate features purposeful oil retention grooves that ensure consistent lubrication to the camshaft's trust surfaces under all operating conditions. The grooved design traps and distributes oil more effectively than smooth alternatives, reducing friction and wear while maintaining the precise end-play clearance required in LS cylinder heads. The compact profile—measuring 6.6 by 8.3 inches with a thickness of 0.65 inches—allows proper fitment without interfering with other engine bay components, while the 0.53-pound weight keeps rotating assembly mass minimal.

LS engine enthusiasts, professional machine shops, and performance builders rely on this component across all LS variants—from the LS1 and LS2 to the modern LT generation platforms. Proper installation requires careful measurement of cam end-play during assembly; the thrust plate must be selected to achieve the manufacturer's specification (typically 0.004 to 0.008 inches) to prevent premature wear or valve train damage. Installing the LS Cam Thrust Plate with Oil Retention Grooves is standard practice during any bottom-end refresh, head rebuild, or complete engine assembly where peak reliability and performance are priorities.
