Features
Removes the factory rake
Most vehicles leave the factory sitting lower in front. A leveling kit adds front height so the body sits even from bumper to bumper.
Front lift only
The kit works on the front suspension and leaves the rear at its factory height, so the change is focused and the parts count stays low.
Method matched to the suspension
Strut spacers suit coil-over struts, forged torsion keys suit torsion bar fronts and replacement springs suit coil front axles. ReadyLIFT uses the method each platform calls for.
Clearance for bigger tires
The added front height opens the wheel wells for a larger tire. ReadyLIFT lists a tested tire size for each application.
Designed around factory geometry
ReadyLIFT engineers each kit to its vehicle so the suspension works close to its original design after the lift.
Fitment & Compatibility
Fit guidance: Fits: 2011-2019 Chevrolet Silverado 2500 HD/Silverado 3500 HD & GMC Sierra 2500 HD/Sierra 3500 HD. Check your vehicle's trim, drivetrain and factory suspension against these notes before ordering.

Installation
Type: front leveling · Install: per-vehicle, see each kit's install sheet · Afterward: alignment, headlamp aim, ADAS check
This kit installs using the steps in ReadyLIFT's instructions for this vehicle. Plan on a wheel alignment after installation and have headlamp aim checked. Vehicles with camera, radar or sonar driver-assistance systems need those systems checked and recalibrated, which can require dealer tools. ReadyLIFT recommends installation by a certified mechanic and says to read the full instructions before starting. Tire sizes are ReadyLIFT guidance based on specific wheel and tire brands, so test fit every combination. Larger E-rated tires have stiffer sidewalls than stock C-rated tires and can make the ride feel firmer.
ReadyLIFT estimates about 5 hours for this kit, give or take 1 hour, not counting the alignment or mounting wheels and tires.
