Installation
Type: front leveling with shocks · 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 truck. 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.
