COMP Cams 09+ Dodge Hemi 5.7/6.4 V8 VVT Stage 1 HRT 221/229 Hydraulic Roller Master Cam Kit

The Micro Surface Enhancement (MSE) finishing process on these COMP Cams HRT camshafts is a notable detail, significantly increasing their strength and performance. This process reduces surface roughness and boosts the effective load-bearing area by 250%, allowing for much higher loads. This is particularly important for the HRT Turbo Stage 1 Hydraulic Roller Master Cam Kit, designed for 2009 and newer Dodge 5.7L Eagle and 6.4L Apache HEMI engines with VVT, especially when paired with responsive, street-type turbo systems.

These camshafts utilize advanced lobe designs from COMP Cams, focusing on maximizing horsepower and torque for turbocharged and supercharged applications. The "Low Shock Technology" (LST) profiles are engineered to improve stability at higher RPMs while also being easier on your valve springs, which can extend their life and reduce load loss. This kit is organized into stages, with this being Stage 1, suitable for builds that maintain limited phaser control for good off-idle response. It's a popular choice for those looking for street-oriented performance gains.

When installing this kit, be aware that it requires a COMP Cams DOD Delete Kit, upgraded valve springs (like the COMP Cams 26918 springs), and either a phaser limiter or lock kit, depending on your specific engine application. Please note that this camshaft is not CARB approved and cannot be shipped to California.
