<strong>TECHNICAL NOTES:</strong><br /> <strong>Spacer thickness to lift amount is NOT a 1 to 1 ratio.</strong><br /> <strong>To raise the front up 3",the spacer thickness is less than 3".</strong><br /> <strong>Strut spacer installation alters the angle of the lower control arm,and this accounts for an additional lift beyond the actual thickness of the spacers.</strong><br /> Before driving the vehicle,making sure ALL hardware are torqued to factory specs.<br /> After installing the kit,the truck needs to be aligned back to factory spec.<br /> <br /> <strong>Fitment:</strong><br /> 2007-2021   Silverado 1500   2WD/4WD<br /> 2007-2020   Tahoe   2WD/4WD<br /> 2007-2020   Suburban 1500   2WD/4WD<br /> 2007-2013   Avalanche   2WD/4WD<br /> 2007-2021   Sierra 1500   2WD/4WD<br /> 2007-2020   Yukon   2WD/4WD<br /> <br /> <strong>Kit Includes:</strong><br /> 2 x Front Strut Spacers<br /> Installation Hardware<br /> Installation Instruction<br /> <br /> <strong>MZS Leveling Lift Kit are CNC machined out of billet aluminum.They are the strongest and would not crack over time.
