Product Details

The COMP Cams Xtreme 4x4 hydraulic flat tappet camshaft is engineered specifically for off-road and high-performance street applications in Chevrolet big block engines (396-454 cubic inches). This camshaft delivers aggressive performance with a 226/234 degree advertised duration split, providing excellent low-end torque and strong mid-range power ideal for 4x4 trucks, rock crawlers, and street machines that demand robust performance.

Key Specifications:

  • Advertised Duration: 226° intake / 234° exhaust
  • Hydraulic flat tappet design for reliable street performance
  • Optimized for Chevrolet big block 396-454 engines
  • Xtreme 4x4 grind designed for torque-focused applications
  • Compatible with stock valve springs and components in most applications

This camshaft provides the ideal combination of drivability and performance for trucks and muscle cars that need strong acceleration and pulling power. The hydraulic flat tappet design ensures quiet operation and easy maintenance, while the duration specifications deliver noticeable performance gains over stock camshafts. Professional installation and proper break-in procedures are recommended to ensure optimal performance and longevity.
