Steeda's Adjustable Blower Belt Tensioner for Shelby GT500 creates more belt wrap around blower pulley for less belt slip with smaller pulleys and higher boost applications.

Rather than just being a stationary idler with zero adjustment like competitors designs, Steeda's kit is a true adjustable tensioner allowing you to set the proper tension regardless of pulley size.

In addition, one single part number will fit most blower designs out there, from the stock blower, Ford Racing TVS, Vortech, Lyschholm, and Whipple 2.9 and 3.4L designs. Note: this part will not fit Kenne Bell 4.2L blowers.

Includes a billet aluminum pulley, all hardware and bracket to mount to engine. Installation is a bolt on installation with no modifications of any kind required.
