I had the shocks installed in Sturgis 2025 on my 2021 HD Tri-Glide. It was worth upgrade. My wife and Ienjoy the smoother ride. The shocks absorb the bumps a lot smoothe we would recommend these shocks on a trike.

Took a chance on a company that I'd never heard about before and couldn't be happier
Took a chance on a company that I'd never heard about before and couldn't be happier. Fast and professional install and the company cares about their customers. Made sure I was 100% happy with the setup before the considered the job done. Night and day difference from stock suspension with 45k miles on it. Don't hesitate to do business with this company.
