Picture this:

You've finally brought the truck home. It represents everything you've worked for, yet at this moment, it appears just like every other vehicle that rolled off the lot. Stock height. Stock stance. Sitting a little nose-down, a little apologetic.

Now, envision it three inches taller. Level. Planted. A custom-colored lift system, expertly designed to catch the light in a finish you selected. Not black. Not raw. A striking blue that perfectly complements your wheels. A unique two-tone overlay that no one else at the meet can replicate — because only you have chosen it.

That encapsulates the difference between the truck you purchased and the truck you built.

And here's what it truly offers you: every morning, as you approach it, you catch yourself grinning. Not just on show day — every day. Because this truck isn't like every other vehicle on the lot. It's uniquely yours, and you get to drive it.

That's the core reason we exist. Love what you drive.

This is where your journey begins.

Why Most 4.5" Kits Leave You Flat

Here's what many competitors provide: a spacer, a bag of brackets, and one color choice. Typically black, or raw if you're fortunate.

Want it powder-coated to match your build? Expect to call for a quote, wait, and pay extra. Cross your fingers that it arrives in the right shade.

Want to visualize it on your truck before committing? Good luck. Most companies expect you to invest a significant amount and trust it will look right when the box arrives at your doorstep.

And the components themselves? Generic. The same kit found on thousands of other trucks.

There is a superior way to approach this.

Build a Stance That's Unmistakably Yours

The TSO 4.5" Lift System grants you the one feature that other kits often overlook: complete control over how your truck looks.

Select from 12 standard powder coat colors — or match any color in the Prismatic Powders catalog, with over 5,500 options available. Create a two-tone effect. Coordinate your brackets with your wheels. Make a bold statement on the trail or a sleek sleeper on the street. The choice is yours, every single piece.

And you can visualize it before you spend a dollar. Our interactive builder allows you to render your exact setup in real-time — change a color, add an overlay, and see immediate updates in both appearance and price. No quotes. No guessing. No more "I hope it matches."

See it. Build it. Drive it.

Oh — and It Drives Like It Should

You came here for the aesthetics. Here’s the bonus you receive.

Most 3" kits elevate the front but compromise everything else. A simple spacer alters your front axle, reduces your caster, and misaligns your track bar and drag link. This leads to wandering, darting, and the frustrating steering that tarnishes the reputation of lifted trucks.

Our system operates differently. Factory caster on these trucks measures a mere 2.5°. Our radius arm drop bracket relocates the factory arms 4.5 inches, achieving a caster angle between 3° and 4° — more caster than you had when it left the assembly line. This is what enables the truck to track dead straight, center itself in the lane, and return the wheel to its position after a turn. The track bar drop and corrected drag link realign your steering, effectively eliminating bump steer.

You'll experience this difference on your very first on-ramp.

But you'll see it every time you walk up to the truck.

Choose Your Front: Radius Arm Drop or Full 4-Link

Radius Arm Drop — included. This feature reuses your factory radius arms, lowering them by 4.5" to establish a caster angle of 3-4°, delivering a clean, planted, and finely-tuned front end right from the outset. Powder-coated to match the rest of your build.

Front 4-Link — the upgrade. This option replaces your radius arms entirely with a precision four-link front end. More hardware on display allows for greater customization and color options — and it maintains control over your caster and pinion throughout the full range of travel, not just at ride height. The result is improved articulation, a smoother ride when the front end is engaged, and the most refined front end we offer.

Here's the best part: when you opt for the 4-Link, the cost of the radius arm drop is credited toward the upgrade, meaning you won’t pay for both.

Complete the Truck: Mini Cradle + Traction Bars

A lift provides height. This combination ensures it appears finished.

Incorporate the mini cradle and traction bars, and your entire build comes together — the rear fills out, the lines seamlessly connect from front to back, and your color scheme extends throughout instead of stopping at the front axle. With the 4-Link or radius arm drop, this is the component that elevates your truck from lifted to complete.

As it enhances the aesthetics, it also performs beneath the surface. The traction bars optimize power delivery while eliminating axle wrap and wheel hop under hard acceleration or when towing. Utilizing the same in-house fabrication and custom color — front to back, one truck, one vision.

One note: the traction bars are the only elements of the build that necessitate drilling and tapping for installation. All other components bolt to factory locations.

WHY TSO BUILDS DIFFERENT

See It Before You Build It Our builder does not simply provide a "Stage 1 / Stage 2" parts list and leave you to figure it out. It guides you through your truck, one decision at a time:

1. Select your colors.
2. Choose between radius arm drop or full 4-Link?
3. Add traction bars + mini cradle?
4. Select shocks?
5. Add a steering stabilizer?
6. Lock it in — and build your truck.

Real-time rendering. Live pricing. You see precisely what will arrive at your door, before you commit.

Build on Your Timeline Start with the 4.5" System and add components as your build progresses. Each piece is engineered to integrate seamlessly — lay the foundation now, and complete your vision when you're ready.

Made in Blountville, Tennessee Every bracket is laser-cut in our facility. Every component is powder coated in-house. Every system is assembled by our dedicated team. We use heavy-duty, USA-sourced materials, with no outsourcing, and we provide a Limited Lifetime Warranty for your peace of mind. Crafted by individuals who understand the importance of quality — because they drive trucks too.

COMMON QUESTIONS

Can I really choose any color? Absolutely. We offer 9 standard colors included in the base price, plus access to the entire Prismatic Powders catalog — over 5,500 options. Two-tone overlays are available on every component. Use the builder to visualize your specific colors before placing your order.

Does my rear lift too? This is primarily a front-lift system. It levels out the factory nose-down rake for a planted, aggressive stance — the front will sit slightly higher than the rear. This is the look many owners desire; if you want additional rear height, consult us about pairing it with rear options.

Is it difficult to install? The 4.5" System is completely bolt-on — every component attaches to factory locations, with no drilling, tapping, or welding required. The only exception is if you add traction bars, which will require some drilling and tapping.

Radius arm drop or 4-Link — which is right for me? The included radius arm drop establishes 3-4° of caster and performs excellently for a street-and-tow truck. The 4-Link is designed for those seeking the ultimate front end, increased customization, and optimal ride quality when the suspension is engaged. Additionally, the cost of the radius arm is credited toward the 4-Link upgrade, so you won’t incur double costs.

Will it still drive correctly after a lift? It will perform better than many stock trucks. The factory caster is only 2.5°; our drop bracket sets you at 3-4°, and we correct the track bar and drag link. Your truck will track straight and center in the lane.

Do I need to purchase everything at once? No. Begin with the 4.5" System and add traction bars, shocks, a stabilizer, or upgrade to a 4-Link whenever you are ready. Everything is designed to work together.

How long until it ships? Typically, you can expect 1-2 weeks from order to shipment. All powder coating is performed in-house in Blountville, TN.
