Pulleys & Pulley Systems

Metco Upper Pulley - $259.99

Metco Motorsports is now offering a precision-made supercharger pulley upgrade for the Hellcat!  Like all Metco Motorsports pulleys, this pulley is an interchangeable unit that is based on a precision-machined, electroless nickel-plated steel pulley hub, an interchangeable pulley drive ring, and a stock-appearing front pulley cover.  The pulley ring and cover are anodized in black, and all included fasteners are stainless steel or zinc plated. 

Please choose your desired pulley ring size from the drop-down list below.  All components are available separately, so once you have this pulley on your Hellcat, a boost change is as simple as changing the outer pulley drive ring.  All boost level changes require the appropriate PCM revisions and the proper supercharger belt.  Please contact us for tuning these pulley combinations.

No tools included. This is the full pulley kit not just the outer ring.

Note: The Bwoody Anti-Slip pulley is recommended for upper pulleys smaller than 2.85".

BWoody Hellcat Crank Pin Kit - $79.99

Pinning the crankshaft pulley is a necessity on every Hellcat. Catastrophic engine damage can occur if the lower pulley spins too much on the crank. This pin kit is easy to install and creates a 3/4" long keyway in the crankshaft and pulley without the need to remove the pulley. 

BWoody Hellcat Anti-Slip Idler - $339.99

This bolt on idler pulley and bracket aid significantly in preventing belt slip with smaller upper pulleys. We have seen this product work on our own cars at the track!
