Product Details

The COMP Cams Xtreme Energy K21-225-4 is a complete hydraulic flat tappet camshaft kit engineered for Chrysler 383-440 big block engines. This performance camshaft features a 240/246 duration split designed to deliver increased midrange power and torque while maintaining excellent street manners and reliability.

Complete K-Kit Includes Everything You Need:

  • Xtreme Energy hydraulic flat tappet camshaft with 240/246 duration
  • Hydraulic flat tappet lifters
  • High-performance valve springs matched to cam specifications
  • Valve spring retainers
  • Valve locks (keepers)
  • Valve stem seals
  • Timing chain set for precise valve timing
  • Assembly lube for proper break-in
  • Installation instructions and decals

The Xtreme Energy series camshafts utilize advanced lobe profiles that maximize performance across the RPM range. This kit is ideal for street performance applications where improved throttle response and power gains are desired without sacrificing driveability. The 240/246 duration split provides strong low-end torque with excellent midrange pull, making it perfect for street/strip vehicles and performance street builds.

All components are precision-manufactured and quality-matched to ensure optimal performance and longevity. The included timing set ensures accurate cam timing, while the assembly lube provides critical protection during initial engine break-in.
