COMP Cams CK201-337-17 HRT Stage 2 Supercharger Hydraulic Roller Camshaft Kit 5.7L/6.4L HEMI

The COMP Cams CK201-337-17 is a Stage 2 Supercharger HRT (High RPM Technology) Hydraulic Roller Camshaft Kit engineered for Gen III HEMI engines equipped with Variable Valve Timing (VVT). Delivering an estimated 169 horsepower gain, this kit is purpose-built for larger blower setups and more race-oriented builds, with dyno-verified performance through 7,500+ RPM.

HRT Series Technology:

• Low Shock Technology — Advanced lobe profiles engineered to maximize horsepower while improving valvetrain stability at high RPM
• Micro Surface Enhancement (MSE) — Proprietary finishing process that reduces surface peak roughness by 65% and provides a 250% improvement in effective load bearing area for higher load capacity
• Higher exhaust duration and increased lift deliver the broadest powerband and maximum top-end power for forced induction applications
• Hydraulic roller design for reliable street/strip durability with an operating RPM range of 2,000–7,000

Camshaft Specifications:

Important Installation Notes:

• Requires a COMP Cams DOD/MDS Delete Kit — the cylinder deactivation system must be disabled
• Requires upgraded valve springs (COMP Cams #7240 springs recommended)
• Requires a COMP Cams phaser lock kit (not phaser limiter) for VVT applications
• Custom ECU tuning is required
• Not CARB legal — not for street use in California or other CARB-compliant states

The CK201-337-17 camshaft kit is the ideal choice for serious forced induction HEMI builds running larger superchargers or blowers where maximum top-end power and high-RPM capability are the priority. For a complete kit that also includes lifters, see companion part MK201-337-17.
