7 Inch Lift Kit | Cast Steel | N3 Struts | Chevy/gmc 1500 (14-18 & Classic)

Built for Chevy and GMC 1500 owners who want aggressive stance and serious tire clearance, this 7-inch lift kit from Rough Country delivers a leveled, head-turning profile while keeping you compatible with factory 18- or 20-inch wheels. You'll run 37–40 inch tires without cutting corners — and the anti-axle wrap rear blocks preserve your truck's factory ride comfort instead of fighting geometry issues common with standard lifts.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.

What's included

• Steel Control Arm Knuckle — maintains proper suspension geometry and fits cast-steel OEM control arms on 2014–18 platforms.
• 7-inch Crossmember Box — laser-cut precision design maximizes ground clearance for off-road performance and obstacle navigation.
• 174 Universal Kit Box — complete hardware and fastener package for secure, flawless installation.
• N3 Shock Pair — nitrogen-charged dampers tuned to complement the 7-inch lift and maintain ride quality on- and off-road.
• Loaded Strut Pair — front struts pre-assembled and ready to bolt in, saving installation time and ensuring correct valving for the new ride height.
• Fabricated Rear Blocks — stronger than cast alternatives and engineered with anti-axle wrap technology to eliminate binding under load.

Important notes

• Requires cutting and drilling. Confirm whether your stock control arms are cast aluminum, cast steel, or stamped steel before ordering — contact us for a visual reference.
• Does NOT fit Denali or Denali Ultimate models equipped with Magnetic Ride Control.
• Does NOT fit models with eAssist (ECO Hybrid) package due to additional drivetrain components and sensor placement.
• Models with a mass damper on the front differential must have it removed to ensure adequate clearance when lowering the differential.
• 18-inch or larger wheels are required. If running tires wider than 35×12.50 R20, offset wheels will be required, and trimming may be necessary — test fit wheels prior to installation.
• To retain factory wheels, a 0.25″ wheel spacer (SKU: 1065) is required.
• Installation of larger tires requires Rough Country's Speedometer Calibrator (SKU: 90009) to maintain accurate speedometer readings.
