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

This mantra served Henry Ford well in 1908, but in 2025, it simply does not suffice.

Today’s industry standard? Basic black.

If you desire something different, the traditional route involves purchasing a kit, waiting for delivery, seeking a powder coater, and enduring an additional two weeks of uncertainty. You deserve better.

We developed TSO because we were tired of that inefficiency.

Introducing the TSO 3" Custom Leveling Kit, the first bolt-on leveling system designed your way—offering 12 premium colors, full customization options, and two-tone capabilities, all shipped directly from our Blountville, TN facility.

No waiting. No cutting. No settling.

Experience a custom suspension setup that commands attention and admiration before you even lower the tailgate.

3" WITHOUT THE HACK JOB.

Them: Want 3" of lift? Prepare to grab an angle grinder and risk cutting your frame. Measure carefully.
Us: We engineered clearance directly into the control arm, ensuring a true bolt-on installation. No cutting. No fabrication. No regrets.

3-hour DIY install. Zero permanent modifications.

The interactive truck builder allows you to visualize your setup in real-time—before you place your order.

Select your base color. Choose your overlay. Add FOX shocks. Witness your truck come to life.

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