What's included

• Driver and passenger-side knuckles — Precision-machined replacements that maintain factory axle position and angle for proper drivetrain alignment.
• Crossmember box — Heavy-duty 1/4-inch thick laser-cut steel that anchors the lift geometry without requiring differential modification.
• Torsion bar drop kit with overload brackets — Reconfigures the factory torsion suspension to achieve full 7-inch lift while keeping the ride smooth and compliant.
• Vertex 2.5-inch front shocks (pair) — Adjustable-range dampers tuned for 5–7 inch lift applications on 2500/3500HD models.
• Vertex 2.5-inch rear shocks (pair) — Matched 3.5–7.5 inch travel for coordinated suspension geometry and response.

Important notes

• Does NOT fit dually models.
• ONLY fits models equipped with rear overload springs.
• Does NOT fit AT4X or ZR2 models, as both are factory-lifted 1.5 inches with Multimatic DSSV dampers.
