Len Performance was developed in the heart of the American Midwest by riders that are passionate about the powersports industry and the machines they ride. We set off to develop a line of high performance shocks that we could rely on whether we were on the trails in Minnesota or in the backcountry of Wyoming. We knew what we wanted, a rebuildable reservoir shock that is tunable, adjustable but also user friendly. By partnering with world class suppliers we have done just that. We have launched our 5 stage compression and rebound adjustable shock series.
