At DMG Motorsports, we present the PSR Primary Chain Tensioner, a durable manual adjustment solution designed to help avoid overtightened primary-chain issues on compatible Harley-Davidson applications. Machined from billet T6061 aluminum and built with heavy-duty components, this tensioner installs using OEM hardware for a straightforward upgrade. The 581-89000 listing is identified for Sportster models from 2007–2017 and FXD models from 2006–2017; it is intended for use with a 34T sprocket only.
