Product Details

COMP Cams is well-known for performance valvetrain components, and their HRT (High Rev Technology) camshafts are designed to give your engine more power while being easier on the springs. This Master Cam Kit, the MK112-300-11, is a Stage 1 'No Springs Required' (NSR) kit specifically for Dodge Gen III HEMI engines that do not use Variable Valve Timing (VVT). It's built to give you a great boost in mid-range torque and excellent overall power, making it a solid choice for heavier vehicles or when you want noticeably better throttle response.

This kit takes the guesswork out of upgrading your HEMI's camshaft. The HRT lobe profiles are engineered to maximize horsepower and improve stability at higher RPMs, all while reducing stress on your valve springs for better durability. COMP Cams has tested these profiles extensively with various valvetrain components to ensure they work together perfectly for maximum horsepower and reliability. This Master Kit includes everything from their Cam Kit – camshaft, phaser limiter, pushrods, valve springs, retainers, locks, seats, and seals – plus upgraded, drop-in performance lifters for a more complete and robust upgrade.

The Stage 1 NSR grind is ideal for drivers looking for a significant improvement in the mid-range, which is where you'll feel it most during everyday driving and when accelerating. It's designed to work with a wide range of Dodge and Chrysler vehicles equipped with the non-VVT 5.7L or 6.1L HEMI engine, such as the Dodge Challenger, Charger, or Chrysler 300. This kit is a substantial upgrade that can add up to 170 horsepower, depending on your specific application and other modifications.
