The Harley Davidson applications are developed using the same race proven street V4S street damper combined with a beautifully machined billet aluminum top-clamp, on some applications. Like all GPR Stabilizer products, these are all bolt-on. No drilling, welding, or cutting to your original equipment. Must use a 3"+ riser or T-bars on some applications. Road Glide / Street Glide kits mount on the underside of the lower triple clamp. A top triple clamp is not changed or included for the Glide, the new Lowrider, Lowrider S and FatBob. Frame mounts and Base Plate are machined aluminum and steel hardware all anodized black. The damper colors available are black, red, blue, gold and orange. Please specify what color(s) you would like at time of checkout.
