ReadyLIFT 6” + 2” Big Lift Kit – Total 8” of Trail-Dominating Performance
Fits 2022–2024 Chevy Silverado 1500 ZR2 & GMC Sierra 1500 AT4X

Unlock the full potential of your ZR2 or AT4X with ReadyLIFT’s game-changing 6” Big Lift Kit, designed to work seamlessly with the factory 2” lift—delivering a true 8 inches of total lift. This kit is purpose-built for serious off-roaders and overland enthusiasts who want massive ground clearance, big tire capability, and factory ride comfort.

Key Benefits:

• 8” of Lift (6” Kit + Factory 2”) – Clears up to 37x12.50 tires on 9” wide wheels with 0 offset — no trimming required. Minor trimming may be needed for -18 offset.

• Factory Geometry Retained – Proprietary lower strut clamshell design keeps your factory struts in place for OE ride quality and reliable performance.

• Maximum Strength Build – 3/16” steel plate crossmembers and full-width skid plate provide uncompromising durability on the trail.

• Heavy-Duty Differential Drops – Boxed & gusseted 1/4” plate steel brackets reduce torsional stress and keep your front differential safe under load.

Premium Suspension Upgrades (6” Kit Only):

• Tubular Steel Upper Control Arms – Built tough with maintenance-free pivot bushings and 1-ton-grade ball joints for long-term reliability and corrected alignment geometry.

• Angled Top-Mount Strut Extensions – Engineered to optimize shock angles and extend performance lifespan.

• Lower Pre-Load Strut Spacers – Slightly increase spring rate to better handle unsprung weight from oversized wheels and tires.

Rear-End Lift Includes:

• Fabricated Steel Rear Blocks – With integrated bump stop landings for a smoother ride and rear-end protection.

• Rear Shock Extensions – Retain use of your factory performance shocks without sacrificing travel or comfort.

Built-In Peace of Mind:

• Backed by the ReadyGuard Powertrain Warranty, so you can hit the trails with confidence knowing your investment is protected.

Engineered for the AT4X/ZR2 Platform:

Built off the success of our best-selling AT4 and Trail Boss lift designs, this system has been refined specifically for the AT4X and ZR2 chassis. Forget the rattles and ride harshness—ReadyLIFT delivers a premium, smooth-driving experience on any terrain.

⚠️ Fitment Note:
