Why Choose ReadyLIFT?

We don’t just build lift kits—we engineer them for durability, performance, and factory-like ride quality. While others cut corners, ReadyLIFT remains committed to precision engineering, premium materials, and total customer satisfaction. With our lift kits, you get more than just added height—you get peace of mind knowing your truck is equipped to handle anything.

Proven Performance, Ultimate Strength

Building on our top-selling designs for the AT4 and Trail Boss, our engineers have adapted this proven technology to the AT4X and ZR2. Say goodbye to squeaks, rattles, and vibrations—these lift kits ensure a smooth, controlled ride across any terrain.

• Unmatched Strength: Heavy-duty boxed steel front and rear crossmembers and a full-width 3/16" front skid plate offer maximum protection and durability.

• Precision Engineering: 1/4-inch boxed plate steel differential drop brackets with double gussets and a boxed center rib prevent front differential torsional twisting, ensuring long-term reliability.

Optimized Suspension for Bigger Wheels & Tires

Our Big Lift Kits feature specially engineered angled and offset top-mount strut extensions to maintain proper alignment, reducing wear and maximizing shock performance. The lower strut pre-load spacer adds a slight spring rate increase, improving handling and stability with larger wheels and tires.

To lift the rear, we include fabricated steel rear blocks with integrated bump stop landings, plus rear shock extensions to retain factory shock performance and ride comfort.

Built for Adventure, Engineered for Excellence
