Proven on the Track — and the Trail

Our suspension systems aren’t tested in labs; they’re proven in Baja, Mint 400, and Glamis alike. The same race engineering that wins on the podium is what keeps weekend riders confident in the dunes, mountains, and desert.

Race-proven performance, built for real-world adventure.

30 Years of Race-Bred Expertise

Co-founder Todd Tenberoek brings three decades of hands-on suspension tuning from Trophy Trucks to UTVs.

Every click, preload, and setup is backed by data, dirt, and decades of race experience. Not guesswork.

Experience forged in competition, tuned for everyday riders.

Custom-Tailored Performance

No one drives the same line, and no two setups should feel alike. From Maverick X3s to Polaris Pro-Rs, we dial in spring rates, damping, and ride height to match your driving style and terrain.

The perfect setup, whether you’re chasing a flag or just pure fun.

Race-Grade Components, Rider-Proven Durability

We only use premium components: FOX®, KING®, FK®, and SDG-engineered hardware; all built to take abuse from race courses to backcountry trails.

Same precision parts. Same performance standard.

Trusted by Champions, Built for Enthusiasts

Trusted by pros. Tuned for people who love to drive.
