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.\u003c\/p\u003e\u003cp\u003eReadyLIFT estimates about 10 hours for this kit, give or take 1 hour, not counting the alignment or mounting wheels and tires.\u003c\/p\u003e\u003cp\u003eReadyLIFT's installation instructions for this part number are linked under Resources.
