Frame Sliders are one of the smartest investments you can make for your bike, and Woodcraft frame sliders stand out in a market crowded with look-alike options. Their patented design features a universal slider puck that fits nearly all slider models. What makes the Woodcraft design unique is the perpendicular attachment bolt for the puck. Because they do not have to hollow out the center of the puck, they can leave the sliding surface of the puck solid. This provides up to 50% more plastic to slide on, dramatically improving puck life. The side mount also eliminates the hassle of trying to dig out a puck replacement bolt through a distorted hole. The slider bases are fully supported, bolting directly to the frame instead of using a single motor mount. The supported base gives the slider maximum strength to resist bending or breaking. These sliders are a great alternative to unsupported sliders which have been known to actually break engine cases on some motorcycles. The fastest and easiest puck replacement on the market - patent pending design features a slider puck which can be replaced with one bolt. All Woodcraft sliders are designed to the ideal length, giving you protection without too much projection. Perpendicular attachment bolt for the puck. All individual frame slider parts have replacements available. Sold as a set. Note: Some modification may be required depending on application
