Pro-One 39mm Fork Tubes Fits Harley-Davidson 1987-2019 Sportster FXR and Dyna

Pro-One 39mm fork tubes deliver a precision-matched front-end replacement for the Harley-Davidson Sportster XL, FXR, and earlier FXD Dyna chassis with a choice of finish and two length options. The coated finishes bring low friction and corrosion resistance to the fork seals for smoother action and longer service life, while Hard Chrome keeps the traditional polished factory look.

Key Features

• Pair of 39mm conventional fork tubes, each tube with its lower slider bushing
• Three finish options: Hard Chrome electroplated, Black DLC Diamond-Like Coating, or Gold TIN titanium nitride
• Coated DLC and TIN finishes are corrosion resistant and low-friction, helping extend fork seal life
• Two length options: 24.25 inch (stock 39mm length) and 26.25 inch (2 inches over stock)
• Accepts the OEM fork springs, damper rods, and seals – no fork-internal swap required
