Adding taller bars or bars with more pullback can make your stock rubber bushings feel mushy. These solid bushings keep your custom bars tight to the top triple for better control of your rig. These bushings are designed to replace the rubber bushings on most Harley front ends. Kit includes 2 rust proof bolts, 2 rust proof washers, and 4 aluminum bushings. Fits steel and aluminum 33.4 HD trees. Make sure that your tree is not a 35mm tree because they are commonly interchanged. The easiest way to tell is the 35mm have a machined stepped counter bore where the 33.4mm just have a straight hole with pressed in bushings. A tip for removing the old bushings you need to press them out and they only will press out in one direction which is down when looking down on the top of the tree. If you try to push them up you will risk breaking the tree.
