39mm Narrow Triple Trees Kit

U.S. Patent Pending.

  • Upper & Lower Billet 6061 Aluminum Triple Trees
  • 1" Diameter Clear Zinc Plated Steering Stem with Snap Ring
  • Custom, Chrome-Plated Stem Nut
  • Stubby 'OEM-style' Axle with Washer & Nut
  • Pinch Bolt Hardware For Stem & Fork Tubes
  • Made in the USA

Our 39mm Narrow Triple Tree Kit has everything you need to make that Harley narrowglide front end nice and skinny. Included are top and bottom 6061 billet aluminum triple trees, a 1" diameter steering stem, a chrome-plated custom stem nut, a stubby, 3/4" diameter OEM-style axle for running a spool wheel of your choice and the necessary pinch bolt hardware. The center-to-center spacing of the fork tubes is 6", which we find is the perfect blend of narrow style and usability; we don't want you having trouble with clearance between your tire or wheel and lower fork legs! Any spool wheel with a hub 3-3/4" wide or narrower will work.

IMPORTANT NOTES

  • Because these triple trees are 1" narrower than stock, you must use a front spool wheel with a hub that is 3-3/4" wide, or narrower. A wider hub will not work properly for this application while using stock lower legs.
  • There is not enough clearance to run a front brake due to the width of these triple trees.

The top tree has handlebar riser mounting holes spaced 3-1/2" on center. The stem is a super-easy install as it is a slip fit with a pinch bolt to secure it top and bottom; no need to use a hydraulic press to install it. The upper and lower tree have matching pinch bolts for the fork tubes, which slide in place with ease.

The bottom tree has a counterbored mount for a headlight, which makes the install a breeze and allows for a flush-mounted allen head bolt thanks to the counterbore. The bottom tree is designed for an internal fork stop kit (not included), the end result being a super clean and simple look.

If installing on a stock Sportster frame, use SKU 015220 Pro One Internal Fork Stop Kit, and also be sure to pick up a 016521 Steering Stem 1/8" Thick Spacing Washer as you will need it for proper installation (watch the 39mm Narrow Triple Trees Install Video on YouTube for more details). When installing our Narrow Triple Trees on any frame that utilizes neck cups (such as Gasbox full frames and most Harley Big Twins) use SKU 015354 Cycle Standard Stainless Steel Internal Fork Stop Kit. Be sure to also check out our full assortment of 39MM Fork Tubes and 39MM Fork Tube Seal Kits.

Have extended fork tubes, or simply want to ensure your fork is rock-solid so you can corner like you are on rails? Our narrow trees pair perfectly (by design) with one of our 39mm Narrowglide Narrow Fork Braces. This fork brace engages the top lip of the lower fork legs, locking them in sync and providing stability and strength, while matching the trees perfectly.

Designed and made by motorcyclists, for motorcyclists. Our parts are top quality and work flawlessly for a reason. Made in the USA.
