HRT Hyd. Roller Cam 5.7L/6.1L Dodge Hemi

The HRT Hydraulic Roller Cam 5.7L/6.1L Dodge Hemi by COMP CAMS is engineered for builders and enthusiasts seeking reliable valve train performance in modern Mopar applications. This hydraulic roller camshaft addresses a critical need in the Dodge Hemi platform: delivering consistent, efficient valve actuation across the entire RPM band without the complexity of solid roller setups. Whether you're building a street engine, weekend warrior, or performance-focused truck, this cam provides the foundation for responsive power delivery while maintaining OEM-style ease of installation and maintenance.

Hydraulic roller technology eliminates valve lash adjustment and reduces wear on valvetrain components compared to flat-tappet designs, making it the modern standard for Hemi engines. COMP CAMS' HRT profile is optimized for the 5.7L and 6.1L Dodge Hemi's cylinder head geometry and pushrod configuration, ensuring proper valve timing and lift throughout the power curve. The roller design minimizes friction losses and allows tighter valve seat tolerances, translating to improved fuel economy at cruise and responsive acceleration when demanded. At 13.05 lbs, this camshaft is purpose-built for direct bolt-in compatibility with existing Hemi engine blocks and heads, requiring no modification to core engine components.

This camshaft is ideal for 5.7L Hemi owners in trucks, SUVs, and performance cars, as well as 6.1L SRT-8 applications seeking reliable, bolt-on performance upgrades. Installation pairs seamlessly with stock valve springs and pushrods, making it accessible for both professional shops and experienced DIY builders. Proper valve timing verification and clearance checking during installation ensure optimal performance; consult your engine builder or COMP CAMS installation guidelines for torque specifications and setup procedures. Whether you're maintaining reliability in a daily driver or chasing incremental gains in a modified platform, the HRT Hydraulic Roller Cam delivers proven Mopar performance heritage backed by COMP CAMS' engineering expertise.
