Wilbers Fork Spring - Zero friction - Progressive
Wilbers progressive fork springs — ZERO Friction finishing
Our vibratory finishing process (trough vibrator with tailored media) micro-polishes the spring surface. The resulting fine, shiny finish reduces surface roughness and friction — hence ZERO Friction.

Perfect fit, perfect replacement for the factory Showa. 1993 BMW R100R rides like new again!
Very high-quality shocks. Pricing is reasonable for what you get. Super easy install. Highly recommend.
I tried two after market rear shocks on my‘23 Road Glide and wasn’t pleased at all with either set. My wife gave me an evil eye when I-told her I had ordered another set (3rd set) of shocks. About an hour into our first ride on the Wilbers she acknowledged the Wilbers were a huge improvement.
The shocks are very easy to install and make the ride as smooth as can be.
Fantastic upgrade that really improves the ride.
Can’t rave enough about the set-up! Two weeks after installation, I went on a 9 day ride from Staten Island NY to Key West FL and back, with various stops in between. The bike handled so smoothly, it was the best long ride i ever had. Never bottomed out either! I’ve been recommending the Wilber’s Nivomat suspension & EPM Performance to everyone I meet. Thank you.
What a great product. So much better than stock. Easy set up and go. No more 3 different adjustments.
