Increase boost and put more of your supercharger’s potential to work with the GripTec V2 Supercharger Pulley Ring for the 6.2L Supercharged Gen 3 HEMI. Designed for compatible Hellcat, Trackhawk, Demon, Redeye, and related applications, this interchangeable ring allows you to change upper pulley diameter according to the performance goals of the vehicle. Smaller pulley diameters increase supercharger speed, which can increase boost and support substantial horsepower and torque gains when combined with the proper fuel system and calibration.

GripTec’s biggest advantage is its approach to belt traction. The system uses patented GripTec surface technologies designed to increase friction between the pulley and supercharger belt through an engineered grip pattern. This additional traction is intended to reduce belt slip, an increasingly important consideration as pulley diameter decreases and supercharger load rises.

The interchangeable ring design also provides excellent value for Gen 3 HEMI owners who expect their build to evolve. Once the compatible pulley hub is installed, changing boost levels can be accomplished by replacing the outer drive ring rather than purchasing another complete hub and pulley assembly. This makes it easier to adjust the combination as you move from pump gas to E85, add fuel system capacity, upgrade the lower pulley, or pursue a higher horsepower target.

Available pulley diameters range from 2.50 to 3.10 inches, providing options for different supercharger and engine combinations. Pulley size should never be selected based on diameter alone. The factory 2.4L and 2.7L IHI superchargers operate differently, and the correct ring depends on the blower, lower pulley diameter, fuel, injectors, cooling system, desired boost, and intended use.

A pulley change also requires the correct supporting setup. Custom tuning is required, and belt length must be matched to the pulley combination. More aggressive pulley sizes may require larger fuel injectors, additional fuel system capacity, colder spark plugs, improved cooling, and other supporting upgrades. This makes the GripTec ring an excellent component for a complete Dusterhoff Racing power package rather than an isolated modification.

Whether you’re building a responsive street-driven Hellcat, an E85 Trackhawk, a higher-output Redeye, or another compatible supercharged Gen 3 HEMI, the GripTec Supercharger Pulley Ring provides a flexible path to increased boost. Its interchangeable design, multiple size options, and belt-gripping technology make it a valuable upgrade for enthusiasts who want to build their supercharger combination around a specific performance target.
