Cam Bearing - LS Block (1pc)

The Cam Bearing - LS Block (1pc) from Racing Head Service is a precision journal bearing engineered for LS-series engine platforms, where it serves as a critical load-bearing surface for the camshaft. This single-piece bearing maintains precise clearances and alignment as your cam rotates at high RPM, distributing oil pressure evenly to prevent metal-to-metal contact. Whether you're building a stock LS engine or a high-performance stroker, a quality cam bearing is non-negotiable—it's the difference between a long-lived powerplant and catastrophic failure.

Racing Head Service bearings are manufactured to OEM tolerances and material specifications, ensuring proper journal fit and oil film thickness under sustained boost, nitrous, or naturally aspirated operation. The bearing's internal geometry is optimized for LS block casting dimensions, and its micro-finish reduces friction and wear during break-in and long-term use. Proper installation requires careful cleaning of the cam tunnel and application of fresh assembly lube—any debris or improper seating will compromise bearing life and cam lobe wear.

This bearing is essential for LS1, LS2, LS3, LS6, LS7, LS9, and LSA block rebuilds, as well as newer LT-series variants that share LS-compatible architecture. Mechanics and engine builders rely on this component during full engine rebuilds, cam upgrades, or when factory bearings show scoring or excessive clearance. Always replace bearings as a set during major engine work; mixing old and new bearings invites uneven wear and oil starvation.
