Product Details

The COMP Cams CL11-243-4 Xtreme 4x4 camshaft and lifter kit is engineered specifically for Chevrolet big block engines (396-454 cubic inches) in performance street and off-road applications. This hydraulic flat tappet camshaft delivers an aggressive 234/244 degree duration profile that provides strong mid-range to upper RPM power, making it ideal for muscle cars, hot rods, and 4x4 trucks that demand serious performance.

Camshaft Specifications:

  • Advertised Duration: 284°/294° intake/exhaust
  • Duration @ .050": 234°/244° intake/exhaust
  • Valve Lift: .510"/.520" intake/exhaust (with 1.7:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Hydraulic flat tappet design for reliable operation
  • Optimized for engines with 9.0:1 to 10.5:1 compression ratio
  • Recommended RPM range: 1,800-6,000 RPM

Complete Kit Includes:

  • High-performance hydraulic flat tappet camshaft
  • Assembly lube for proper break-in
  • Installation instructions
  • COMP Cams decals

This cam profile produces a noticeable lope at idle and delivers strong acceleration and pulling power. It requires aftermarket converter (2,400-2,800 stall recommended) and works best with headers and performance intake manifold. The Xtreme 4x4 series is specifically designed to provide excellent low-end torque for off-road and towing applications while maintaining strong top-end power for performance street use.
