Upgrade the rigidity, stability, and overall appearance of your Harley-Davidson 39mm front end with the Pro-One Performance 39mm Triple Tree. CNC-machined from solid 6061-T6 aluminum, this triple tree features an increased lower clamping area designed to reduce lateral and torsional fork flex for a more rigid and stable front-end setup.

The upper tree includes a machined cut-out for clean cable and wire routing and is designed to accept standard 3-1/2" O.C. risers. Available in Black or Raw finishes, the kit includes the upper and lower trees, steering stem, top-mounted headlight bracket, billet aluminum top nut, external fork stops, and necessary mounting hardware.
