Our Story
Built in California. Engineered to outlast the terrain you throw at it.
Welcome To Pro One Design
We're a local manufacturer based in California, obsessed with the details that make suspension systems actually last. From the welds to the powder coat to the geometry, every kit we ship is designed to outperform and outlast what comes off most shelves.

Built In California
Our shop is in the heart of the Central Valley, where the dirt is deep and the testing never stops. We design, machine, weld, and finish every kit under one roof — no black-box factories halfway across the world.
That proximity is how we hold tolerances tight and how every kit leaves our dock inspected by someone who actually wrenches on trucks.
Engineered With Precision
Our Pro-Spec'd coilovers use precision-valved nitrogen shocks with stainless steel shafts and custom reservoir mounting. Every component is tuned for a balanced ride on-road and off.
Billet upper control arms, greasable bushings, FK uniball joints — the parts list reads like an OEM engineering spec because that's how we build every kit.

What We Stand For
Quality
Every part is engineered, tested, and built in our California shop. No shortcuts, no imported junk.
Expertise
Decades of off-road suspension design baked into every kit. Built by drivers, for drivers.
Support
Real humans answer the phone. We stand behind every product and walk you through install when needed.
