Vortech Superchargers 8-Rib Pulley Upgrade - No Crank Damper Pulley (2005-2009 Mustang GT) 4FU116-005
8-Rib Drive Conversion Without Damper Pulley for 2005-2009 Mustang GT
The Vortech Superchargers 8-Rib Pulley Upgrade - No Crank Damper Pulley (PN 4FU116-005) is engineered to convert an existing 6-rib supercharger drive system to a more robust 8-rib configuration on 2005-2009 Ford Mustang GT 4.6L applications. This version is intended for builds that already utilize a compatible crank damper pulley or where a damper upgrade is not required.
By increasing belt surface area and traction, the 8-rib setup helps reduce belt slip, maintain consistent boost under load, and extend belt life - making it a smart supporting upgrade for higher-boost or aggressively driven supercharged Mustang GTs.
Why Convert to an 8-Rib Drive?
As power and boost levels rise, factory 6-rib belt systems can struggle to transmit sufficient drive without slip. Vortech's 8-rib conversion increases contact area at the pulleys, allowing the supercharger to maintain commanded boost levels and deliver more consistent performance.
This upgrade is commonly recommended for performance-focused builds and is often considered essential when stepping up boost or pulley ratios.
