Description

These pieces are the highest quality supercharger pulleys for your Shelby GT500. This pulley is a 10-rib 2.6 inch diameter drive pulley for the stock Shelby GT500 Supercharger. It is meant to have a stock look while allowing you to gain performance with an additional 4 psi of boost on the stock supercharger.

AFTERMARKET COMPUTER CALIBRATION REQUIRED
As with any supercharger pulley upgrade, an aftermarket computer calibration is required and is not included. The Ford Racing ProCal tuner does not support this supercharger pulley change.

MUST USE GT 9000 IDLER TENSIONER ARM ASSEMBLY
The OEM tensioner arm does not have enough range of motion to ensure proper belt tension. Failure to purchase and install our tensioner arm assembly when using a smaller than stock supercharger pulley will result in belt slippage under acceleration.

Why these pulleys are better

Each pulley consists of precision machined grooves to ensure proper fitment with the belt. Inferior designed grooves will rip belts apart. The pulley to belt contact area is a critical design element and the pulley design is the result of many revisions to virtually eliminate slippage.
To eliminate the issue of the pulley slipping on the supercharger shaft, these pulleys are honed bore, round & straight within .0002.
Proper Lead-in is designed into each pulley to ensure that the it goes on straight.
Made In the USA
