Built for GMC Sierra Denali 1500 owners who want aggressive ground clearance without sacrificing driveline geometry, this 3.5-inch lift kit delivers increased ride height and room for 33–35 inch tires while maintaining proper axle angles through differential drop spacers. Rough Country engineered this kit specifically for Magnetic Ride Control–equipped Denali models, pairing fabricated lift blocks with MOOG upper control arms to give you a platform that looks as good as it performs.

What's included

  • 3.5" Lift Kit Box — the core suspension lift engineered for your GMC Sierra 1500 Denali with Magnetic Ride Control, delivering the full 3.5 inches of height.
  • 3.5" Spacer Box — supplemental spacer components that work with the main kit to achieve final lift geometry.
  • Red Forged Upper Control Arms — upgraded MOOG ball joints pre-installed to reduce assembly time and guarantee proper alignment geometry from the factory.
  • Differential Drop Spacers — maintain the correct axle angle and driveline pinion slope, preventing premature wear on U-joints and ensuring smooth power delivery.
  • 3-Inch Fabricated Rear Lift Blocks — stronger and longer-lasting than cast alternatives, resistant to cracking and environmental damage.
  • Differential Skid Plate — protects the differential from trail debris and rock strikes.

Important notes

  • Magnetic Ride Control required: This kit is engineered exclusively for GMC Denali models equipped with Magnetic Ride Control. It will not fit non-MagneRide Denali or standard Sierra 1500 trucks.
  • Upper control arm compatibility: Fits cast aluminum and cast steel OEM upper control arms. Does NOT fit 2016+ models with stamped steel upper control arms.
  • Cutting and grinding required: Professional installation must include cutting and grinding operations to properly fit the new lift blocks and spacers.
  • Mass damper removal: If your truck is equipped with a mass damper on the front differential, it must be removed as part of this installation.
  • Wheel spacers recommended: To retain your factory wheels, Rough Country offers 0.25-inch wheel spacers (part #1065) for clearance between the tire and suspension components.
  • Tire clearance: This lift is engineered to safely accommodate 33–35 inch tires. Larger sizes may interfere with suspension travel or body panels.

Why customers pick this at Road Runner

  • Alignment performed in-house as part of your lift install — corrected caster and geometry ensure straight tracking and even tire wear.
  • Rough Country lifetime warranty backed locally by our shop; if anything fails, we stand behind it.
  • Installed by technicians who do Denali lifts every week — no learning curve, no comebacks.
  • MOOG upper control arms and fabricated blocks outlast cheaper cast alternatives.
  • Differential drops preserve pinion angle, protecting your driveline from premature wear.
