Kawi Performance Ultra 300/310 Automatic Belt Tensioner Arm Kit

The Kawi Performance Belt Tensioner Arm Kit directly replaces the factory cast aluminum arm adn components that weaken over time at critical points causing belt slip and diminished boost output. The CNC machined billet arm houses stainless steel bearings that are protected with viton seals and secured with 316 stainless steel snap rings to ensure smooth operation. 316 stainless steel bushings and oversized washers provide a more durable buffer between the billet aluinum arm and mounting points. Modified arm angle increases belt pressure minimizing belt slip in rough conditions. Billet arm is hard anodized to prevent corrosion. Accepts OEM idler pulley or aftermarket pulley included with RIVA Racing ‘K3’ Supercharger Pulley Kit.
