2007-2014 Ford Mustang Shelby GT500 Whipple 3.000" Black 10-Rib 4-Bolt Supercharger Pulley

2007-2014 FORD MUSTANG SHELBY GT500
WHIPPLE 3.000" BLACK 10-RIB 4-BOLT SUPERCHARGER PULLEY

Built for Whipple supercharger applications, this 3.000" black 10-rib 4-bolt pulley is engineered for 2007-2014 Ford Mustang Shelby GT500 combinations that demand precise fitment, dependable belt control, and the quality expected from Whipple.

Each pulley is machined from 6061-T6 billet aluminum and finished in black anodizing for long-term wear and environmental protection. Whipple engraves the running diameter on every pulley and machines in lightweight pockets to help reduce rotating mass, while the integrated guard feature helps control unwanted belt wandering during aggressive use.

Pulley changes are a proven way to adjust supercharger speed, which can affect boost and overall power potential on properly matched combinations. As a general rule of thumb, every .125" of pulley change can alter boost by roughly 1 psi, though actual results will vary based on the application, belt system, supporting components, and calibration.

Whipple has been a leader in twin-screw supercharging since 1987, building high-performance products for enthusiasts who demand more from their combination. Like Whipple's supercharger systems and components, this pulley reflects the company's commitment to quality, performance, and application-specific engineering.

Designed, manufactured, and assembled in Fresno, California, Whipple products are built in the USA and backed by decades of supercharging experience. Whipple supercharger pulleys are application-specific and should only be ordered for the intended setup. There are no returns or exchanges on used pulleys, so fitment should be verified before installation.

Whipple Superchargers shipping & returns

• Limited warranty: a Whipple product suspected of being defective is returned under Whipple's returns procedure; Whipple inspects it and decides whether it is covered and whether to repair or replace it, then ships it back by ground service.
• Superchargers make unique sounds; noises Whipple considers normal for a supercharger are not covered.
• Kits that list a model year, vehicle model or VIN need those details with the order so the right calibration is built.
