Lowering Link Kit This fully adjustable lowering links can transform the rear of the motorcycle to any height between factory and lowered 4 inches (100 mm). This link is made up of a aluminum connecting lever and two Carbon steel rod ends that have ball bearings with a lube-free teflon race. Carbon steel rod ends with teflon race are used to protect against binding and seizing from metal on metal corrosion when threading. It also has four aluminum bushings for easy fitment. These aluminum bushings inserted into the rod ends make this link the same thickness as your stock link. Easy to install, n o need to remove bolts and disassemble the rear suspension every time you raise or lower your bike! Simply loosen the nuts and turn the center piece to find the desired ride height and then re-tighten down the adjusting nuts to secure in place.
