3.5 Inch Lift Kit | Mag-ride | Alu/cast Steel | Gmc Sierra 1500 Denali (14-16)

Built for GMC Sierra 1500 Denali owners who want 3.5 inches of lift without sacrificing the sophisticated ride quality of Magnetic Ride Control, this Rough Country lift kit delivers increased ground clearance and a more aggressive stance while maintaining proper axle geometry through differential drop spacers. The kit accommodates 33–35-inch tires and is fully reversible — you can return to stock if needed.

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

• 3.5" Lift Kit Box — the core suspension lift assembly engineered for GMC Sierra 1500 (2007–2018) and Sierra 1500 Denali (2014–2016) applications.
• 3.5" Spacer Box — precision-machined spacers that maintain consistent ride height and geometry across front and rear.
• Forged Upper Control Arms — MOOG ball joints pre-installed for caster correction and improved handling; sealed boot design with grease-relief valve resists contamination and extends joint life.
• 3-inch Fabricated Rear Blocks — stronger and more durable than cast alternatives, with longer service life and superior resistance to environmental damage.
• Differential Drop Spacers — preserve proper axle angle and driveline geometry without modifying the frame.
• Differential Skid Plate — protective shield for enhanced undercarriage durability.

Important notes

• ONLY fits GMC Denali models equipped with Magnetic Ride Control — verify your truck has MagneRide before ordering.
• Compatible with cast aluminum and cast steel factory upper control arms only. Does NOT fit 2016+ models with stock stamped steel upper control arms.
• Installation requires cutting and grinding; this is not a bolt-only procedure.
• If your front differential has a mass damper, it must be removed as part of the install.
• The new lift block replaces your factory-equipped block.
• To retain factory wheels, add 0.25" wheel spacers (Rough Country #1065).
