NOTE: This is the PULLEY ONLY.

Tweak your boost levels with this GripTec "upper" pulley upgrade for your Hellcat blower. This bolt-on hellcat pulley upgrade allows you to change the spin-rate of the Hellcat's supercharger and more spin can equal more power. A Griptec upper pulley upgrade is a cheap and effective way to boost power.

ZPE (the company behind the GripTec pulley system) has their own mounting "hub" (the ZPE hub) that's required to use this Hellcat pulley. If you already have the ZPE hub you can simply buy a pulley by itself. Otherwise you can buy a pulley and hub combo or you can buy a hub separately. The hub comes with a set of 8 titanium screws for weight savings and strength.

The GripTec pulleys are made from billet 7075-T6 aerospace grade aluminum which is Stronger and harder than 6061-T6. What makes these Hellcat pulleys really shine is the "GripTec" technology that's applied during the machining process.

GripTec Micro Machining Tech For LS9/ZR1 Supercharger Pulleys

GripTec is a micro-machining technology that allows for maximum grip force to be applied to the Hellcat's supercharger pulley without damaging your blower belt. More importantly the GripTec technology essentially deletes belt slip on the Hellcat blower allowing all of the crank's power to be transferred to your blower via the pulley.
