Details from Comp cams: This CNC machined billet aluminum tensioner is a direct bolt-on replacement for the original equipment spring loaded tensioner and can be torqued to the exact belt tension required. Best of all, it controls damper resonance often encountered in high rpm applications or when aftermarket balancers are utilized. By controlling resonance, belt slippage - a common problem in high performance LS1 engines - is eliminated.
