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 tree from bike. Available in Contrast Cut or Black Ops, which has an aggressive yet subtle textured black and a gloss black finish on one part.


Fits 39mm forks on 1987 thru 1994 FXR, 1988 to present XL Sportsters (except XL 1200 S), and 1991 thru 2005 Dyna (except FXDX)
