COMP Cams Supercharger Stage 1 HRT Hydraulic Roller Cam Kit

2009+ Dodge 5.7L HEMI / 6.4L HEMI with VVT

CK201-335-17

Overview:

The COMP Cams Supercharger Stage 1 HRT 221/233 Hydraulic Roller Cam Kit is engineered specifically for 2009 and newer Dodge 5.7L and 6.4L HEMI engines equipped with Variable Valve Timing (VVT). Designed to optimize performance in supercharged and turbocharged applications, this camshaft kit delivers significant gains in average power and torque while maintaining engine reliability. Ideal for enthusiasts seeking a balance between street drivability and enhanced forced induction performance, the Stage 1 HRT camshaft provides improved throttle response and durability under boost.

Utilizing advanced lobe designs and Low Shock Technology, this camshaft kit reduces valve spring load and improves stability at higher RPMs, making it a perfect upgrade for 2.5L and smaller superchargers on the 5.7L Eagle or 6.4L Apache engines. This kit requires complementary upgrades including a COMP Cams DOD Delete Kit, upgraded valve springs, and a phaser limiter or lock kit to ensure proper function with VVT systems.

Key Features:

The COMP Cams Supercharger Stage 1 HRT camshaft kit incorporates cutting-edge technology to maximize power and durability for forced induction Dodge HEMI engines:

• Low Shock Technology: Advanced lobe profiles designed to maximize horsepower while reducing valve spring load and improving high RPM stability.
• Micro Surface Enhancement (MSE) Finish: A proprietary finishing process that reduces surface roughness, increases strength, and improves load-bearing capacity by 250%.
• Optimized for Supercharged/Turbocharged Engines: Specifically developed lobe designs to enhance power and torque gains under boost conditions.
• Stage 1 Calibration: Ideal for mild to moderate supercharger setups, especially with 2.5L and smaller blowers.
• Compatibility with VVT Systems: Requires phaser limiter or lock kit to maintain limited phaser control for improved off-idle response.
• Durability Enhancements: Easier on valve springs, reducing load loss and extending component life.
• Complete Kit Requirements: Must be used with COMP Cams DOD Delete Kit and upgraded valve springs (part #26918).

Construction & Design:

COMP Cams employs state-of-the-art engineering and manufacturing techniques in the HRT camshaft series. The cam lobes are precision-ground and finished with the Micro Surface Enhancement (MSE) process, which significantly improves surface integrity and fatigue resistance. This results in a camshaft capable of handling higher loads and stresses typical of forced induction applications. The hydraulic roller design reduces friction and wear, contributing to smoother operation and longer service life. The camshaft profiles are carefully optimized to balance aggressive performance gains with valve train stability and durability.

Installation & Fitment:

This camshaft kit is designed for direct fitment on 2009 and newer Dodge 5.7L and 6.4L HEMI engines equipped with Variable Valve Timing. Installation requires removal of the factory camshafts and upgrading the valve springs to COMP Cams part #26918 to handle the increased demands. Additionally, a COMP Cams DOD Delete Kit is mandatory to disable the factory Displacement on Demand system. For proper VVT function and to maintain off-idle throttle response, installation of a COMP Cams phaser limiter or lock kit is also required. Professional installation is recommended to ensure correct timing and component compatibility.

What's Included:

• COMP Cams Stage 1 HRT Hydraulic Roller Camshaft (221/233 profiles)
• Installation instructions and technical support documentation
• Note: DOD Delete Kit, upgraded valve springs, and phaser limiter/lock kit sold separately

Ideal For:

This camshaft kit is perfect for Dodge HEMI enthusiasts running mild to moderate supercharger setups, particularly those with 2.5L or smaller blowers. It suits street performance builds that require improved power and torque without sacrificing drivability or engine longevity. It is also an excellent choice for those upgrading their 5.7L Eagle or 6.4L Apache engines who want to maintain some phaser control for better throttle response off idle.

COMP Cams is a leading performance valvetrain manufacturer, known for camshafts and supporting components built for everything from mild street upgrades to full race engines. Their product range covers camshafts, lifters, valve springs, rocker arms, and timing/valvetrain parts—key pieces for dialing in powerband, drivability, and RPM capability.
