Ported LS9 Corvette ZR1 LPE Snout

The GripTec pulleys are made from billet 7075-T6 aerospace grade aluminum which is Stronger and harder than 6061-T6. What makes these Corvette ZR1 (C6) 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 ZR1's supercharger pulley without damaging your blower belt.
