RSD FORK PRELOAD ADJUSTER 49mm FXD06-15 For Harley-Davidson

The RSD Preload Fork Adjusters allow on-the-fly fork spring preload adjustment. Easily increase or decrease preload with an Allen wrench to alter the handling characteristics for a softer or stiffer ride. These pre-load adjusters replace the OEM top fork caps to provide you with up to 1.15" (29mm) of preload adjustability. Easy installation, as there is no need to remove forks or top triple trees from bike.
