O-Ring Seal LSX Block Cam Thrust Plate

The O-Ring Seal LSX Block Cam Thrust Plate is a precision rubber seal designed for GM LS-series engine blocks. This component is essential for maintaining crankcase pressure control and preventing oil leakage at the camshaft thrust surface, which is crucial for engine longevity and performance in various applications, including street use and racing.

Engineered to fit precisely into the LSX block camshaft thrust plate assembly, this seal measures 3.95 x 0.25 x 4.7 inches. Its elastomer composition is designed to resist thermal cycling and degradation from engine oil, ensuring reliable performance over extended use. This part allows for easy replacement of worn seals without the need for full engine disassembly, making it a cost-effective solution for maintenance.

Engine builders and enthusiasts working with LS-series platforms, whether naturally aspirated or boosted, can rely on this seal to maintain proper thrust bearing preload and prevent oil contamination. It is an essential component for anyone rebuilding an LSX engine block or performing maintenance after performance upgrades.
