What's included

• Front and rear 6-inch knuckle boxes — cast steel components engineered for extreme durability and precise geometry correction.
• 6-inch crossmember box — high-clearance design optimizes suspension articulation and maintains driveline angles.
• Front skid plate — reinforces chassis strength and protects undercarriage during off-road use.
• N3 shock pair (front) — application-valved absorbers tuned for balanced performance on and off pavement.
• Loaded strut pair (rear, 6-inch) — pre-assembled and pre-loaded, requiring no disassembly for hassle-free installation.
• Universal hardware kit — all fasteners, brackets, and mounting hardware needed for complete installation.

Important notes

• Model-specific fitment: This kit fits Trailboss and AT4 models only — does NOT fit Denali models with Magnetic Ride Control, "Classic" 2019 models (2018 body style), or diesel-engine trucks.
• Wheel requirements: Does NOT fit factory 20-inch wheels. Aftermarket wheels 20-inch or larger are required, with 4.5-inch backspacing mandatory. Test fit wheels before installation.
• Tire clearance: Kit supports tires in the 33–35-inch range on 10-inch-wide wheels with proper backspacing.
• Installation impact: Requires cutting and drilling as part of the install process.
