Shock Absorber Type 640 TS Road
The Harley Davidson Street Glide ST and Road Glide ST are based on the U.S. racing series “Kings of Bagger,” and as such, already feature improved riding dynamics compared to the “Special” variants. However, the Wilbers suspension system further enhances ride comfort by optimizing the negative spring travel of both the fork and shock absorber. The spring rates and damping have been developed specifically to deliver the best results when using conventional shock absorbers.
For maximum comfort in both solo and two-up riding, the proven Wilbers Nivomat kit is also available for these models.
The high-quality Wilbers Adjustline mono shock absorber was the foundation for our twin shock development. As with all Wilbers products, only top-grade materials are used, and our modular design allows for special lengths or custom requirements. Adjustable in rebound and continuously in spring preload, the Wilbers twin shocks include ABE certification and a 5-year warranty — offering exceptional performance at a remarkable value.

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.
Front cartridges for my 2021 Harley heritage softail classic. Solid and stable w no bouncing and jittering. Huge difference from stock.
I have about 50 miles riding on this shock so far. It works and feels great.
I had hyperpro one inch lowered shock and springs installed at epm, on my 2025 z650, great service, (thank you guys). Before the install i could feel every bump in the road, after the ride was very smooth except for very large holes. total different bike. Very satisfied.
The shock seems to do it's job - it absorbs road bumps and rebounds quickly to take on the next one.
