The HRT Camshaft Series uses the newest and most advanced lobe designs from COMP Cams in order to produce some of the highest average power and torque increases available for turbo and supercharged engines. The “Low Shock Technology” features lobe profiles designed to maximize horsepower while improving stability at higher RPM. These profiles are also easier on the valve springs, enhancing durability and reducing load loss. These new HRT Camshafts receive the Micro Surface Enhancement (MSE) finishing process as a standard feature, which increases strength and performance by reducing surface peak roughness and provides a 250% improvement in the effective load bearing area, allowing for much higher loads.Organized into stages, these new options range from mild street up to heavily modified race-oriented builds. All HRT Turbo & Supercharger Camshafts require a COMP Cams DOD Delete Kit and upgraded valve springs. Depending on application, 5.7L-6.4L w/ VVT 2009+ engines also require either a COMP Cams phaser limiter or lock kit.
Best camshaft for larger turbochargers with optimized low backpressure hot side. Dyno tested to 7500+ RPM. (Req DOD delete, 7230 springs & Phaser LOCK)

The .585” Lift COMP Cams Beehive Valve Spring Kits for GM 6.6L Duramax Diesel Engines include everything needed to upgrade from stock springs: Beehive Valve Springs, steel retainers, spring seats and valve seals. Beehive Valve Springs feature a reduced diameter at the top of the spring to allow the use of a smaller and lighter retainer, reducing overall valve train weight. The lighter valve train combined with the stronger spring allows the engine to rev higher without concerns of valve float while an increased spring rate maintains valve train stability at elevated RPM to allow the use of more aggressive camshafts. The unique ovate Beehive shape not only has higher load but is more dynamically stable than the factory spring, ensuring valve train stability at elevated RPM and boost pressures.
Able to support .585″ valve lift, this Beehive Spring Kit for ’01-’05 Duramax Diesels includes springs, retainers, seats and seals for an easy drop-in upgrade. Thanks to a unique Ovate Beehive design, this kit handles higher RPM and boost.

With a .600″ maximum lift, these Beehive Valve Springs were designed for hydraulic or Solid flat tappet cams as well as hydraulic Roller cams. They allow Big block engines to turn more RPM. COMP Cams Beehive Valve Springs deliver increased valve train stability and a much lighter valve train. This is achieved with less spring pressure for better valve control and reduced weight of both the spring and retainer. The unique Beehive shape handles valve train stress more efficiently to eliminate damaging harmonics and increases high RPM horsepower and durability. The oval/multi-arc wire shape places the maximum area of the wire at the point of highest stress to handle valve train stress more efficiently and allow better heat dissipation for longer life. Because of the unique Beehive design, the valve train can handle more RPM and more aggressive Camshaft profiles.
