Overview
The Whipple Superchargers 10-Rib Belt System Upgrade is a race-proven solution designed to dramatically improve belt grip and drive stability on 2018–2023 Ford Mustang 5.0L Coyote platforms equipped with Whipple W185 or W235RF 5-bolt superchargers. Whether you’re running a stock long block or a high-power build, this system delivers the confidence and durability needed for aggressive street driving and track use.
Engineered by Whipple using premium components throughout, the 10-rib conversion reduces belt slip under high load, maintains consistent boost, and improves reliability as power levels climb.
Race-Proven Design & Components
This upgrade features an ATI harmonic balancer (available in stock diameter or optional 20% overdrive), a heavy-duty Whipple billet tensioner, and lightweight, pocketed hard-coat anodized aluminum pulleys.
