Paxton Superchargers 6-Rib 4.00" Supercharger Drive Pulley (1996-1999 Mustang Cobra) 4PFK036-400
6-Rib 4.00" Supercharger Pulley for 1996-1999 Mustang Cobra
The Paxton Superchargers 6-Rib 4.00" Supercharger Drive Pulley (PN 4PFK036-400) is a precision-machined pulley engineered for 1996-1999 Ford Mustang Cobra applications running compatible Paxton centrifugal supercharger systems. Designed for the 4.6L DOHC modular Cobra engine, this pulley provides accurate blower speed control and dependable belt engagement for stable, repeatable performance.
With a 4.00-inch diameter and 6-rib belt profile, this pulley is commonly selected for conservative boost setups, break-in configurations, or applications prioritizing thermal headroom and long-term reliability.
Boost Control & Drive Accuracy
Supercharger pulley diameter directly affects impeller speed and manifold boost pressure. The 4.00" size reduces blower speed relative to smaller pulleys, helping manage intake air temperatures and belt traction while maintaining smooth, predictable power delivery.
Paxton pulleys are manufactured to tight tolerances to ensure proper alignment and vibration-free operation, minimizing belt slip and reducing wear on belts and supercharger bearings at higher RPM.
Designed for Paxton Supercharger Systems
This pulley is intended for use with Paxton centrifugal superchargers installed on 1996-1999 Mustang Cobra vehicles. Proper pulley selection should always consider supporting modifications such as fuel system capacity, charge cooling, engine internals, and ECU calibration.
