What's included

• Front lifted leaf springs — engineered for your model with 4 inches of lift and paired with factory-tuned geometry.
• Rear lifted leaf springs — maintain balance and load-carrying capacity with the rear component of the kit.
• N3 shock absorbers (front and rear) — application-valved shocks deliver balanced performance on and off the road.
• Spring bushings — allow smooth articulation at all suspension pivot points.
• Raised steering arm — corrects caster angle to maintain steering feel and tire wear after the lift.
• Brake line relocation brackets — keep brake lines clear of suspension travel.
• U-bolts and hardware — all fasteners needed to secure springs and components.
• Installation kit — brackets and miscellaneous hardware specific to your Suburban.

Important notes

• This kit only fits models equipped with 56-inch rear leaf springs. Verify your vehicle's spring length before ordering.
• If your Suburban has a factory front sway bar, drop brackets are recommended (SKU: 1019) to maintain suspension clearance.
• If your vehicle is equipped with factory front quad shocks (4 total front shocks), add the Factory Quad Shock kit (SKU: Q20027) to ensure proper damping across all corners.
