2.95" 10-Rib Underdrive Pulley Pack for 1986-1993 Mustang 5.0
The Vortech Superchargers 10-Rib Pulley Pack (PN 8E020-295) is engineered for 1986-1993 Ford Mustang 5.0L applications utilizing underdrive accessory configurations. This pulley pack is ideal for Fox Body Mustang builds that require increased belt traction and consistent boost control, particularly in higher-output or sustained RPM applications.
Whether you're upgrading from a 6-rib or 8-rib system to a 10-rib drive or fine-tuning boost output on an existing underdrive setup, this Vortech pulley pack includes the necessary components to properly configure your supercharger drive with maximum belt contact and reduced slip.
Underdrive-Specific 10-Rib Design
This 2.95" underdrive pulley pack is designed for Mustangs running underdriven accessories, where accessory speeds are reduced compared to factory configurations. The 10-rib belt interface significantly increases surface contact area over traditional 6-rib and 8-rib systems, helping maintain stable boost delivery under higher loads.
Pulley diameter and spacing are matched to Vortech's underdrive drive system geometry to ensure proper belt tracking, durability, and long-term reliability.

FAQs

A 2.95" pulley can slightly reduce peak boost compared to smaller pulleys while still maintaining excellent belt traction with a 10-rib drive. - Can this pulley pack be used on non-underdrive systems?
No. This pulley pack is engineered specifically for underdrive accessory configurations and should not be used on non-underdrive setups.
