What's included

• 6-inch front leaf springs — pair of lifted springs engineered to support the additional weight and height at the front axle.
• 4-inch rear leaf springs — pair of lifted springs that raise the rear and maintain proportional stance.
• N3 shock absorber pair (front) — application-valved for balanced on and off-road performance.
• N3 shock absorber pair (rear) — matched valving delivers consistent damping across the suspension travel.
• Raised steering arm — corrects caster geometry and steering response after the lift is installed.
• Spring bushings — polyurethane-lined for durability and consistent articulation.
• U-bolts, hardware, and installation kits — complete fastener and bracket package for secure mounting.

Important notes

• If equipped with a front sway bar, sway-bar drop brackets (SKU 1019) are recommended to maintain proper suspension geometry.
