2.50-Inch 8-Rib Supercharger Pulley

The Griptek ZPE-ZZ250BV2Z8 is an ultra-lightweight pulley upgrade designed to work with the ZPE Pulley Hub system, specifically for Factory GM LSA/TVS superchargers. Constructed from strong and hard billet 7075-T6 aerospace-grade aluminum, this 10-bolt pulley measures 2.50 inches in diameter and features 8 ribs. This pulley incorporates GripTec® V2 micro-machining technology, engineered to provide maximum grip on the component and belt without causing damage. This advanced grip technology effectively eliminates belt slip, allowing you to achieve the maximum potential performance from your supercharger. Unlike some other aftermarket pulleys, this 2.50-inch option does not require grinding of the LSA snout for installation. Installation of this pulley requires tuning. The pulley has a black finish with a Type III Anodized, Class 2, Hard Coat. Note that this upgrade requires larger injectors for proper operation.
