COMP Cams HRT Turbo Stage 2 Hydraulic Roller Camshaft
2003–2008 Dodge 5.7L / 6.1L HEMI
112-332-11
Overview:
The COMP Cams HRT Turbo Stage 2 Hydraulic Roller Camshaft is engineered specifically for Dodge 5.7L and 6.1L HEMI engines from 2003 to 2008. Designed to maximize power and torque gains in turbocharged and supercharged applications, this camshaft utilizes advanced lobe profiles to deliver impressive performance improvements while maintaining engine reliability. Ideal for enthusiasts seeking a balance between street drivability and high-RPM power, the Stage 2 camshaft enhances engine response and efficiency under boost.
Built with COMP Cams' latest Low Shock Technology, this camshaft reduces valve train stress and improves stability at elevated RPMs. It is a perfect upgrade for those running larger turbochargers with optimized low backpressure setups, offering a dyno-tested capability up to 7500+ RPM.
Key Features:
This camshaft incorporates cutting-edge technology and design elements to ensure superior performance and durability:
- Low Shock Technology lobe profiles for increased horsepower and improved valve train stability
- Micro Surface Enhancement (MSE) finishing process for a 250% increase in effective load bearing area
- Optimized for turbo and supercharged engines, especially larger turbochargers with low backpressure hot side
- Designed to reduce valve spring load loss and enhance spring durability
- Dyno tested to operate reliably beyond 7500 RPM
- Stage 2 profile balances aggressive power gains with street-friendly drivability
- Requires COMP Cams DOD Delete Kit and upgraded valve springs for proper installation
- Compatible with Dodge 5.7L and 6.1L HEMI engines without Variable Valve Timing (VVT)
Construction & Design:
The HRT Turbo Stage 2 camshaft is manufactured using premium materials and advanced engineering techniques to withstand the rigors of forced induction performance. The Micro Surface Enhancement (MSE) finishing process significantly reduces surface roughness on the cam lobes, increasing strength and load capacity. This results in improved wear resistance and longevity under high-stress conditions typical of turbocharged engines.
COMP Cams' Low Shock Technology further refines the lobe design to minimize valve train shock, reducing stress on valve springs and related components. This thoughtful engineering ensures the camshaft delivers consistent performance while extending the life of your valvetrain.
Performance & Sound
The Stage 2 camshaft is optimized to deliver substantial gains in horsepower and torque across the RPM range, particularly under boost. Its aggressive yet controlled profile enhances throttle response and engine efficiency, making it well-suited for high-performance turbocharged builds. The camshaft’s design also contributes to a more aggressive exhaust note, reflecting the increased engine output without compromising drivability.
Installation & Fitment:
This camshaft is designed for direct fitment on 2003–2008 Dodge 5.7L and 6.1L HEMI engines without VVT. Installation requires the use of a COMP Cams DOD Delete Kit to disable the factory Displacement on Demand system, as well as upgraded valve springs (7228 springs recommended) to handle the increased valve train demands. For 2009 and newer 5.7L–6.4L HEMI engines with VVT, additional components such as a phaser limiter or lock kit are necessary, but these do not apply to this specific camshaft.
Professional installation is recommended to ensure proper timing and valvetrain setup, maximizing performance and reliability.
What's Included:
