Product Details

The COMP Cams MK112-300-11 Stage 1 HRT Master Camshaft Kit is engineered specifically for Dodge Gen III 5.7L HEMI non-VVT applications, delivering a complete valve train upgrade package designed to maximize performance and reliability. This comprehensive master kit eliminates the guesswork in selecting compatible components for your HEMI engine build.

Low Shock Technology

Features advanced HRT (High Response Technology) lobe profiles that maximize horsepower while improving valve train stability at higher RPM ranges. The Low Shock Technology design reduces stress on valve springs, enhancing overall durability and minimizing load loss over time. Through extensive Spintron and dyno testing, COMP Cams engineers have precisely matched these components to deliver optimal performance in modern HEMI applications.

Complete Master Kit Includes:

  • HRT camshaft with optimized lobe profiles
  • Upgraded drop-in performance hydraulic roller lifters
  • High-performance pushrods
  • Beehive valve springs (no additional springs required)
  • Chromoly steel retainers for increased strength
  • Valve locks, spring seats, and valve seals

Performance Benefits:

  • Stage 1 power gains for street/strip applications
  • Improved throttle response and mid-range torque
  • Enhanced high-RPM stability and valve train control
  • Reduced valve spring fatigue for extended service life
  • Precisely matched components for optimal reliability

This Stage 1 kit is designed for non-VVT (Variable Valve Timing) 5.7L HEMI engines and includes everything needed for a complete valve train upgrade. The master kit configuration provides upgraded lifters compared to the base CK-Kit, offering a more comprehensive performance solution for enthusiasts seeking reliable horsepower gains.
