Dynojet 16-21 Polaris XP Turbo/ProXP Dura Series CVT Belt Kit

The GM LS engines with the factory spring loaded belt tensioners become prone to throwing belts when used in performance Applications and with aftermarket balancers. These bolt-on Billet LS Belt Tensioners are a fully adjustable solution for controlling potentially damaging resonance and maintaining desired belt tension.
This billet belt tensioning assembly for GM LS1/2/3/6/7 helps stop the throwing of serpentine belts by absorbing potentially damaging resonance.
If used with 2010+ Camaros, the belt must be changed.
