"You can have any color you want, so long as it's black."

That worked for Henry Ford in 1908.

But it doesn't work in 2025.

The industry standard? Basic black.

Want something different? You know the drill: Buy the kit. Wait for delivery. Find a powder coater. Wait another 2 weeks. Hope they get it right.

We built TSO because we were tired of that BS.

The TSO Upper Control Arms are the first bolt-on upper control arms built your way—12 premium colors, complete custom options, two-tone capability—shipped direct from our Blountville, TN facility.

No waiting. No cutting. No settling.

Just a custom suspension setup that turns heads and breaks necks before you even drop the tailgate.

3" WITHOUT THE HACK JOB.

Them: Want 3" of lift? Great. Grab the angle grinder and cut your frame up. Hope you measured right.
Us: Engineered clearance directly into the control arm. True bolt-on installation. No cutting. No fab work. No regrets.

3-hour DIY install. Zero permanent modifications.

The interactive truck builder shows you exactly what your setup will look like—in real time—before you order.

Pick your base color. Choose your overlay. Add FOX shocks. Watch your truck come to life.

No guessing. No hoping. Just your custom build, rendered on your screen.
