LS GEN III/IV Cam Retainer Thrust Plate

The LS GEN III/IV Cam Retainer Thrust Plate by TOP STREET PERFORMANCE is a vital internal engine component designed to control camshaft endplay and maintain precise valve timing in LS-series engines. This thrust plate is particularly useful for those building performance engines or restoring classic LS swaps, ensuring reliability and consistent power delivery.

This thrust plate functions by limiting the forward and rearward travel of the camshaft to a precise tolerance—typically 0.001" to 0.005" of endplay. Excessive endplay can lead to timing drift and engine inefficiency, while insufficient endplay may cause binding and wear. It is engineered to OEM specifications, ensuring compatibility and performance.

Ideal for those working on LS Gen III or Gen IV engines—including 5.3L, 5.7L, 6.0L, and 6.2L variants—this thrust plate is crucial for maintaining optimal engine performance. Proper installation requires careful measurement and shim selection to achieve the desired endplay for your specific engine configuration.
