Want a lowered look, but hate the way lowered suspension feels?

Progressive Suspension’s 412 Series Shocks are designed to have the stance of 1” lowered shocks, and perform like full-length shocks. The result is a shock that sits like an 11.5” shock, but utilizes the full stroke when terrain demands it instead of bottoming out over every bump and dip in the road. The 412 Series Shocks feature a double-wall steel body with nitrogen charged, multi-staged velocity-sensitive valving that delivers smooth, consistent damping. They also have a progressively-wound steel spring that provides superior handling while riding.

Get that custom lowered look without compromise on handling with Progressive Suspension’s 412 Series Shocks.
