Product Details

The COMP Cams MK112-303-11 Stage 2 HRT Master Camshaft Kit is engineered to deliver serious horsepower gains for Dodge Gen III 5.7L HEMI engines without Variable Valve Timing (VVT). This complete master kit takes the guesswork out of valve train upgrades by providing a perfectly matched package of components designed to work together for maximum performance and reliability.

Low Shock Technology for Maximum Performance:

The HRT (High RPM Technology) camshaft features advanced lobe profiles developed through extensive Spintron and dyno testing. These profiles are designed to maximize horsepower while improving stability at higher RPM, reducing stress on valve springs, and enhancing overall durability. The result is a valve train that produces more power with less component wear and reduced load loss.

Complete Master Kit Includes:

  • HRT Stage 2 camshaft with aggressive lobe profile
  • Performance hydraulic roller lifters for enhanced valve control
  • High-performance valve springs (Beehive or Conical design)
  • Chromoly steel retainers for strength and reduced weight
  • Precision valve locks and spring seats
  • Upgraded pushrods matched to camshaft specifications
  • High-quality valve seals for proper oil control

Performance Gains:

Stage 2 HRT packages are designed for enthusiasts seeking substantial power increases, with potential gains of up to 170 horsepower depending on supporting modifications. This kit delivers a noticeable improvement in mid-range to high-RPM power while maintaining acceptable street manners for performance street/strip applications.

Application Notes:

This kit is specifically designed for non-VVT 5.7L HEMI engines. The master kit configuration includes upgraded drop-in performance lifters that are not included in the base CK-Kit version, providing a more complete valve train upgrade solution. Professional installation and proper engine tuning are recommended to achieve optimal results.
