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

Built for Chevy and GMC 1500 owners who want a level stance and serious off-road presence — this 6-inch lift kit eliminates factory rake and opens up tire clearance for 35"–37" rubber on factory 20-inch wheels while preserving that OE look. Heavy-duty fabricated lift blocks, anti-axle wrap rear blocks, and a high-clearance crossmember design combine durability with geometry that keeps ride quality intact.

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 — precision-cast steel steering geometry component ensures correct caster and alignment angles post-install.
• 6" Kit Box — contains laser-cut fabricated lift blocks and all structural mounting hardware.

• Loaded Strut Pair — complete front strut assemblies pre-assembled and ready to bolt on.

Important notes

• Installation requires cutting and drilling. Confirm whether your truck's stock control arms are cast aluminum, cast steel, or stamped steel before ordering — different arm types have fitment implications.
• Does NOT fit Denali or Denali Ultimate models equipped with Magnetic Ride Control suspension.
• Does NOT fit models with the eAssist (ECO Hybrid) package due to additional drivetrain components and sensor placement.
• Front differentials equipped with a mass damper must be removed to ensure adequate clearance during and after lowering operations.
• Larger tires will require Rough Country's Speedometer Calibrator (SKU 90009) to maintain accurate speed readings.
• If using tires wider than 295/60R20, offset wheels will be required and trimming may be necessary — test fit wheels prior to final installation.
• To retain factory wheels, a 0.25" wheel spacer (SKU 1065) is required.
