CNC-machined billet aluminum plates move forward controls backward for shorter riders. Bolt to the frame where the controls mount from the factory. The controls mount 1-1/8″ back and 1″ up from stock location. Made in the U.S.A.. Dyna needs 1-1/8″, FXR/FXST models need 1-3/8″ clearance between exhaust and controls, and between primary and controls, for these to work; may also need to shorten shift and brake rods depending on controls configuration..
