LS Series Billet Aluminum 6 Groove Tensioner Pulley 2.75" Diameter 73mm CNC Machined Universal

Upgrade your LS accessory drive system with this precision CNC-machined 6061 billet aluminum 6-groove tensioner pulley, engineered to fit most LS applications that use grooved tensioner pulleys. Significantly lighter than the factory steel unit, it is machined from premium 6061 billet aluminum with an anodized finish for lasting corrosion resistance in demanding engine bay conditions. A standard replaceable bearing is fitted as standard — allowing the bearing to be serviced independently without replacing the entire pulley assembly, keeping long-term maintenance costs low. At 73mm outside diameter and 23mm width, this pulley delivers accurate belt alignment and tension across the full LS engine family in swap, restomod, and performance build applications.
