These AV&V high-performance valve spring retainers are a significant upgrade over the stock components. Designed to be used with factory Beehive valve springs, they work perfectly with stock-style triple groove valves or AV&V’s single groove valves. The kit includes four retainers and four pairs of the exclusive POSI-CLAMP keepers. These keepers are a real innovation; they use a single groove but clamp the valve both above and below the three grooves, resulting in a 55% increase in strength. This kit fits 2002–2010 air-cooled Buell, 2004–2022 Sportster, and 2005–2017 Twin Cam models, including Dyna, Softail, Touring, and Trike. It is the ultimate setup for valve train security.
