Product Details

The COMP Cams CL12-243-3 Xtreme 4x4 camshaft and lifter kit is engineered for serious off-road and street performance in Chevrolet Small Block engines. This hydraulic flat tappet cam delivers an aggressive 226/234 duration split that provides excellent low-end to midrange torque, making it ideal for 4x4 trucks, rock crawlers, and muscle cars that need strong throttle response and pulling power.

Key Specifications:

  • Advertised Duration: 268°/276° intake/exhaust
  • Duration at .050": 226°/234° intake/exhaust
  • Valve Lift: .462"/.470" intake/exhaust (with 1.5 rocker ratio)
  • Lobe Separation Angle: 110°
  • Hydraulic flat tappet design for reliable street performance

This cam profile is specifically designed for vehicles with automatic transmissions, stock to mildly built engines (up to 9.5:1 compression), and 2,000-3,500 stall converters. The broad torque curve makes it perfect for applications requiring strong off-idle performance and excellent drivability without sacrificing top-end power. Ideal power range is between 1,500 and 5,500 RPM.
