Thump Racing Shelby GT500 HD Belt Tensioner
Thump’s HD belt tensioner will help eliminate belt slip by exerting increased tension on the belt. It is constructed of billet aluminum and includes a high strength bolt for mounting. This tensioner normally comes standard with a 63mm steel pulley but we change them out and pre-install our lighweight series aluminum 63mm pulley along with a premium bearing at no extra cost! ($60 value and half the weight).
- Fits all GT500’s from 2007-2014
