The ReadyLIFT 9-inch Big Lift Kit for 2014-2018 GM 1500 trucks is a complete high-performance suspension overhaul designed to provide maximum lift without compromising comfort. Featuring heavy-duty tubular upper control arms with TCT pivot bushings and thick plate steel crossmembers, this system provides superior strength and precise alignment geometry. The kit is compatible with MagneRide-equipped trucks and utilizes an innovative lower strut extension design to preserve the factory shock performance while enabling the use of aggressive 37-inch off-road tires.

Features

• Provides a massive 9-inch front lift while retaining the factory turning radius.
• Includes new tubular steel upper control arms (UCAs) with TCT pivot bushings for enhanced strength.
• "Clam-shell" style lower strut extensions allow for lift without rotating or flipping factory struts.
• Minimizes track width increase to less than 0.5 inches per side to keep tires tucked properly.
• Compatible with both standard and MagneRide-equipped front suspension systems.
• 3/16-inch thick boxed steel front and rear crossmembers provide a rigid, high-clearance sub-frame.
• Full-width front skid plate constructed from 3/16-inch plate steel for engine and differential protection.
• 1/4-inch boxed plate steel differential drop brackets with double gussets to handle torsional twisting.

Notes

• Not for use on All-Wheel Drive (AWD) applications; 2WD or 4WD only.
• The 9-inch kit allows the factory plastic gravel guard to be reused to maintain proper engine bay airflow.
• Rear lift is achieved through a combination of an add-a-leaf spring and fabricated steel blocks with integrated bump stop landings.
• Vehicle alignment, headlamp aim, and ADAS systems should be checked and adjusted after installation.

Compatibility Notes

• Fits 2014-2018 Chevy Silverado and GMC Sierra 1500 trucks.
• Specifically designed for models with OE Forged Steel or Aluminum/Stamped Steel front suspension (verify your truck's arms before ordering).
• Not recommended for GMC Denali 1500 models equipped with rear MagneRide.
