COMP Cams HRT Blower Stage 2 Hydraulic Roller Camshaft Kit

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

CK201-337-17

Overview:

The COMP Cams HRT Blower Stage 2 Hydraulic Roller Camshaft Kit is engineered specifically for 2009 and newer Dodge 5.7L and 6.4L HEMI engines equipped with Variable Valve Timing (VVT). Designed to maximize power and torque gains for turbocharged and supercharged applications, this camshaft kit is ideal for enthusiasts seeking a high-performance upgrade capable of supporting larger blowers and race-oriented builds.

Utilizing COMP Cams' latest lobe designs and advanced technologies, the HRT series delivers significant improvements in horsepower and torque while maintaining engine stability at high RPMs. This kit is perfect for those who want to push their forced induction setups to the next level with a reliable, dyno-tested camshaft that performs beyond 7,500 RPM.

Key Features:

The HRT Blower Stage 2 camshaft incorporates cutting-edge technology to optimize performance and durability in demanding forced induction environments:

• Low Shock Technology: Specially designed lobe profiles that maximize horsepower and improve valve train stability at higher RPMs.
• Micro Surface Enhancement (MSE): Advanced finishing process that reduces surface roughness, increasing strength and load-bearing capacity by 250%.
• Optimized for Turbo & Supercharger: Engineered specifically for boosted engines requiring aggressive cam timing and lift.
• Valve Spring Compatibility: Requires upgraded valve springs (COMP Cams 7230 springs) to handle increased loads.
• Variable Valve Timing (VVT) Support: Compatible with VVT-equipped 5.7L and 6.4L HEMI engines when used with a phaser limiter or lock kit.
• High RPM Capability: Dyno tested to exceed 7,500 RPM for race-level performance.
• Stage-Based Options: Part of a staged product line ranging from mild street to aggressive race builds.
• Requires DOD Delete Kit: Designed to work with COMP Cams DOD (Displacement on Demand) delete kit for proper operation.

Construction & Design:

The HRT Stage 2 camshaft is manufactured using premium materials and precision engineering to ensure durability and performance under extreme conditions. The Micro Surface Enhancement (MSE) finishing process significantly strengthens the cam lobes by smoothing surface imperfections, which reduces wear and extends service life. The hydraulic roller design reduces friction and valve train stress, while the low shock lobe profiles minimize valve spring load, contributing to improved reliability and longevity.

Each camshaft is carefully ground and balanced to exacting standards, ensuring smooth operation and consistent power delivery throughout the RPM range. This attention to detail makes the HRT Stage 2 camshaft a dependable upgrade for high-output forced induction HEMI engines.

Performance & Sound

With its aggressive lobe profiles and optimized timing, the HRT Stage 2 camshaft delivers substantial gains in horsepower and torque, especially in the mid to upper RPM ranges. The camshaft’s design enhances throttle response and engine efficiency, making it well-suited for larger superchargers and turbochargers. Expect a more aggressive exhaust note characteristic of performance camshafts, adding to the driving experience without compromising daily drivability.

Installation & Fitment:

This camshaft kit is designed for 2009 and newer Dodge 5.7L and 6.4L HEMI engines equipped with Variable Valve Timing. Installation requires removal of the factory camshaft and installation of the COMP Cams DOD delete kit along with upgraded valve springs (COMP Cams 7230 springs). Additionally, a phaser limiter or lock kit is necessary to properly control the VVT system and prevent timing issues. Professional installation is recommended to ensure correct setup and optimal performance.

What's Included:

• COMP Cams HRT Blower Stage 2 Hydraulic Roller Camshaft
• Installation instructions (where applicable)
