The Gen III Hemi market is rapidly expanding, and 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 camshafts available for these 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. The 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 to wild! All HRT Stage 1 Camshafts are No Springs Required, which keeps cost down while still providing awesome horsepower increases over stock. Stages 2 and 3 applications work with COMP Cams Beehive and Conical Valve Springs, but COMP Cams is also introducing new HEMI Valve Spring Kits, engineered to produce the most power and RPM of any current options.
Best HP of any stock piston Hyd Roller cam by taking full advantage of Hemi high lift airflow. Runs great from 3000-7000rpm. Low Shock Technology profiles and #7228 conical valve spring allow 7500RPM+.
Stage 1 available under 112-300-11. Stage 2 available under 112-303-11.

The LST Camshaft Series uses the newest and most advanced lobe designs from COMP Cams. These new lobes provide the potential for major increases in power and torque in Duramax engines when combined with the appropriate tuning. The “Low Shock Technology” features lobe profiles designed to maximize additional engine airflow, which reduces harmful EGTs, while improving stability at higher RPM. These profiles are also easier on the valve springs, enhancing durability and reducing load loss. Organized into stages that allow you to choose your level of performance, Stage 1 Camshafts are No Springs Required and run well with the factory or a performance tune. Stage 2 and 3 camshafts require a COMP Cams #26125 Beehive Valve Spring Kit upgrade but do produce the greatest potential for additional power and RPM when matched with maximum effort tuning.
All out performance, max effort grind. Requires valve spring upgrade, larger turbo, aftermarket pistons and higher RPM.

COMP Cams HRT Camshaft Packages for Dodge Gen III HEMI applications take the guesswork out of choosing the right valve train upgrade package for your specific engine and desired performance.
The “Low Shock Technology” behind COMP Cams HRT camshafts 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. By Spintron and dyno testing these new profiles with many combinations of valve train components, COMP Cams engineers have created valve train packages that are perfectly matched for maximum horsepower and reliability in popular modern HEMI applications. The resulting Stage 1, Stage 2 and Stage 3 HRT Camshaft Packages can add up to 170 horsepower (depending on the application) and are available as base Cam Kits (CK-Kit) or the more complete Master Kits (MK-Kit).
CK-Kits include camshaft, phaser limiter (VVT Hemi only), pushrods, Beehive or Conical Valve Springs, chromemoly steel retainers, valve locks, spring seats and valve seals. MK-Kits include everything found in the CK-Kit with the addition of upgraded, drop-in performance lifters.
Best HP of any stock piston Hyd Roller cam by taking full advantage of Hemi high lift airflow. Runs great from 3000-7000rpm. Low Shock Technology profiles and #7228 conical valve spring allow 7500RPM+.
Available in a CK-Kit under CK112-305-11.

Valve springs with larger diameters require retainers to handle the higher pressures developed by the springs. COMP Cams Steel Retainers are the perfect solution to this problem. COMP engineers used 3D CAD with FEA to design retainers with a modern and advanced contoured top profiling for lower stress, increased lift and a reduction in mass. The retainers are CNC-machined to exact tolerances using CAD/Cam software. All COMP retainers use only high-grade SAE 4140 chromemoly Steel with no lead,
Precision machined from chromemoly steel then black oxided, these 7 degree retainers are designed specifically for 26113/26125 Beehive springs on Ford 4.6 3 Valve applications.
