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
