Better Performance. Whether you're running a smaller pulley on your blower for bigger boost or just looking for stronger performance from your Cobra, this belt tensioner kit is a great addition to your Mustang. It uses factory mounting points on your engine, adding another tensioner pulley that changes the angle of your supercharger belt and creates more wrap around your blower pulley. The result is more contact area between your supercharger belt and your pulley, meaning less belt slip.
Ideal for Big Boost. If you're running a smaller pulley to dial up higher boost on your Cobra, this belt tensioner kit is a must-have to make sure you're getting the most from your mods.
Premium Quality. This premium quality pulley is made from billet aluminum for durability and a great underhood look.
Complete Kit. This kit includes the 100mm (OEM) pulley, mounting bracket, and all necessary hardware for a hassle-free, straightforward installation.
Application. This belt tensioner kit is designed to fit 2003-2004 Mustang Cobras.
