Fitment (fast, simple, verified)
Harley-Davidson Touring models only. Before we finalize your kit, we confirm fitment so you don't get stuck mid-install.
We'll ask for:
- Year + model (Road King / Street Glide / Road Glide / etc.)
- Current front wheel diameter
- Any front-end history (previous rake trees, non-stock fork parts, etc.)
- Fender material preference where applicable: steel or carbon fiber (18 & 21)
FAQ
Do I have to cut anything?
No. On the 18 x 5.5 kit, the upper fork covers come already relieved on the inside for wide-fender clearance. You're not cutting parts in your garage—this is supplied ready for the conversion.
Compatible with front air ride?
Yes—our 21" and 23" kits include fork bump stops, which is what makes the setup compatible with front air ride.
Are the fenders always Arlen Ness?
18 & 21: Arlen Ness (steel or carbon fiber).
23: Custom Fat Katz (Made in the USA).
Do 21 and 23 require geometry changes?
Yes. 21 uses a 7-degree tree. 23 uses the bolt-on neck + tree kit. That's how these conversions are done correctly.
