Tweak your boost levels with this GripTec "upper" pulley upgrade for your LSA blower. The stock LSA blower came on 2nd generation Cadillac CTS-Vs and 5th generation Camaro ZL1s and this bolt-on upgrade allows you to change the spin-rate of the supercharger. A Griptec upper pulley upgrade is a cheap and effective way to boost power.
The GripTec pulleys are made from billet 7075-T6 aerospace grade aluminum which is Stronger and harder than 6061-T6. What makes these ZR1 pulleys really shine is the "GripTec" technology that's applied during the machining process.
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. More importantly the GripTec technology essentially deletes belt slip on the LS9 blower allowing all of the crank's power to be transferred to your blower via the pulley.
