Bbc Cam 288Ar (Solid Roller)

The COMP CAMS Big Block Chevy 288Ar solid roller camshaft is designed for serious engine builders and performance enthusiasts who require reliability in high-RPM, high-lift applications. This camshaft is specifically engineered for Big Block Chevy engines (BBC), utilizing solid roller technology to eliminate the wear patterns associated with hydraulic lifters, ensuring consistent valve timing across extreme operating conditions.

The 288Ar camshaft features a mid-range lift and duration profile optimized for engines operating in the 5,500–7,000 RPM range, striking a balance between street performance and track-capable power delivery. Its solid roller design incorporates hardened steel roller lifters that ride on precision-ground cam lobes, which reduces parasitic friction losses while maintaining exact valve event timing during sustained high-RPM operation.

This camshaft is ideal for those building street performance engines, bracket racing platforms, or dedicated competition mills. The hardened steel construction and precision grinding ensure durability through thousands of heat cycles, making the 288Ar a trusted choice in COMP CAMS' proven catalog.
