GM LS LSR Cam - 285LRRHR13

The COMP Cams GM LS LSR Cam (part number 54-470-11) is a high-performance hydraulic roller camshaft designed specifically for LS-based engine platforms. This camshaft is ideal for automotive enthusiasts and tuners who are looking for enhanced valve lift, extended duration, and optimized overlap characteristics, making it suitable for aggressive street and bracket racing applications.

Engineered with COMP Cams' proprietary lobe geometry, this camshaft reduces friction and promotes consistent valve sealing throughout the lift curve. The hydraulic roller design eliminates the need for manual valve clearance adjustments, providing self-adjusting lash management, which is particularly beneficial when using variable fuel octane or boost pressures. Its cast-steel construction with induction hardening ensures durability even under high-RPM conditions.

The LSR profile is perfect for builders working on LS1, LS2, LS3, LS9, and LSR engine platforms, commonly found in vehicles like the Chevrolet Corvette and Camaro. With compatibility for standard LS-series lifter bores and timing chains, installation is straightforward for those familiar with LS architecture, making it an excellent choice for both street and competition builds.
