What's included

• Steel Control Arm Knuckle — replaces the OEM knuckle to accommodate lift geometry and maintain proper suspension angles.
• 7-Inch Crossmember Box — precision laser-cut frame component that raises the front suspension mounting point and improves ground clearance for off-road obstacles.
• Universal Kit Box (174) — comprehensive hardware and fastener package with all brackets, bolts, and installation components needed for proper fit.
• M1 Loaded Strut Pair (7-Inch) — nitrogen-charged front struts tuned to work with the lift geometry and maintain ride quality at the new height.
• M1 Monotube Shock Pair — rear shocks engineered with anti-axle wrap technology to eliminate common lift-induced binding while preserving factory ride comfort.

Important notes

• Installation requires cutting and drilling. Confirm whether your stock control arms are cast aluminum, cast steel, or stamped steel before proceeding.
• Does not fit Denali or Denali Ultimate models equipped with Magnetic Ride Control.
• Does not fit models with the eAssist (ECO Hybrid) package due to additional drivetrain components and sensor placement.
• Requires 18-inch or larger wheels. Factory wheels will need a 0.25" wheel spacer (SKU 1065) to retain fitment.
• Tires wider than 35×12.50 R20 require offset wheels, and trimming may be required. Test-fit all wheels before final installation.
• Models equipped with a front differential mass damper must have it removed to ensure adequate clearance when lowering the differential.
• Installation of larger tires requires Rough Country's Speedometer Calibrator (SKU 90009) to maintain accurate speed readings.
