Steeda 07-12 GT500 Adjustable Belt Tensioner - Fits stock, TVS, Whipple, and Lyscholm Vortech upgrades - 555-3354

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.

Product Benefits

• Made from Billet aluminum for strength and light weight
• Easily adjustable for proper tension

Belt slip issues on your 2007-2020 Shelby GT500 are no longer a concern with the VMP Heavy Duty Tensioner!

As GT500s get older, factory tensioners become inconsistent in their stiffness and ability to control the belt. This stiffness keeps the stock tensioner from acting quick enough in high-powered applications causing the factory belt to slip, jump, and snap.

Fabricated of Billet Aluminum and precision machined for the '07-'20 GT500, the VMP Heavy Duty Tensioner is strong, durable, and eliminates the issues associated with the stock tensioner. Learn More
