Questions & Answers


I'm changing the lower legs on my 07 Road King with Arlen Ness smooth Hot Legs. Will theses work?

So long as the Hot Legs kit you're working with accepts the stock fork internals, then you shouldn't have any problem fitting these components to your bike.

By Tom

Will this fit my 2015 Roadglide

Yes, so long as you select a 2015 Harley Roadglide before adding to your cart for checkout, you would receive the correct fitting kit.

By Andy

Will this kit work in my 05 road king or do you have the part number for that kit

Yes, just be sure to choose that 2005 Harley Davidson FLHR when adding to your cart.

By Andy

Is the drop adjustable to between 1-2"

It includes detailed installation instructions, it all depends on the riders weight and the length or preload spacer chosen at installation. Both factors directly affect the ride height. Heavier rider, more drop. Less spacer, more drop. At a minimum it will lower the ride 1 inch.

By Staff

Will these fit 2004 FXDWGI?

Yes, Progressive Suspension does produce a set of Mono-Tube fork cartridges to fit the 2004 Dyna Wide Glide both, the carbureted and fuel-injected variants. Just select your machine from our fit guide and we'll send the correct FXDWGI fork cartridges to you, guaranteed!
