Upgrade the ride quality of your Can-Am Defender HD11 with the SDI Terrain Master 2.1 Shock System. Designed specifically for the Defender platform, these rebuildable performance shocks deliver improved comfort, control, and stability whether you're working on the farm, exploring trails, hauling gear, or tackling rough off-road terrain. The factory suspension is built around basic emulsion-style shocks designed to accommodate a wide range of riding conditions. While they provide a comfortable ride for everyday use, they lack the damping control, consistency, and serviceability of a true performance shock. Terrain Master 2.1 transforms the Defender into a more capable, confidence-inspiring machine with improved ride quality and suspension performance. Why Upgrade Your Suspension? Whether you're navigating rocky trails, washboard roads, deep ruts, hauling equipment, or spending long days behind the wheel, Terrain Master 2.1 shocks help keep the suspension composed while reducing harshness and driver fatigue. Unlike factory shocks, the Terrain Master 2.1 features a fully rebuildable performance shock design, allowing the shocks to be serviced and rebuilt rather than replaced. It's an investment that continues to perform for years while delivering significantly improved control both on and off the trail.
