The BTR 5.7 Hemi Truck Norris Camshaft with VVT is a hydraulic roller camshaft designed for 2009+ Gen III 5.7 Hemi engines in Ram trucks, Chargers, and Challengers. Spintron and dyno tested, it delivers gains over the factory cam starting above 2,000 RPM and continues to pull strong to 7,000 RPM, with BTR's in-house dyno testing showing approximately 490 hp at the crank. This grind also adds roughly 1,500 RPM of additional usable operating range over the factory cam while retaining a mild-mannered idle.

This camshaft includes a required VVT limiter (BTR-VVT-HEMI-4CAM) in the box; the BTR-VVT-Hemi-Tool installation tool is needed separately if not already owned. Non-MDS lifters are required (MDS conversion needed if applicable) — compatible lifter part numbers include 05038784AD, 2356, and 2326. BTR recommends valve springs SK017, SK017/TS, or SP021-16, along with the HEMILC-16 valve tip saver and a BTR aftermarket spring kit due to the increased valve lift and RPM potential; a dedicated BTR Hemi valve spring compressor tool (BTRHemiSpringTool) is needed to install the upgraded springs. Hardened pushrods are recommended for power-adder applications, and proper VVT control and engine tuning calibration are needed to realize the camshaft's full potential.
