Engineed to deliver 1 to 3 inches of height adjustment, this coilover system provides essential clearance for up to 33-inch tall tires while drastically upgrading both highway stability and off-road absorption.\u003c\/p\u003e\n\u003cp\u003eSEMA suspension ride quality studies demonstrate that large-bore 2.5-inch shock bodies yield over 50% more fluid displacement than typical 2.0-inch options, preventing thermal shock fade during rapid damping cycles across harsh trail conditions. Built with high-strength cold-wound coil springs carrying a lifetime guarantee, these coilovers feature a compact internal nitrogen reservoir layout designed for tight fitment envelopes. Equip your Silverado or Sierra 1500 with race-proven performance constructed to handle deep sub-zero conditions and heavy trail impacts without compromise.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eShock Body Diameter\u003c\/td\u003e\n\u003ctd\u003e2.5 Inches (Cadmium Plated Body)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReservoir Type\u003c\/td\u003e\n\u003ctd\u003eInternal Nitrogen Reservoir (IFP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLift Height Range\u003c\/td\u003e\n\u003ctd\u003e1.0 to 3.0 Inches (Adjustable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Construction\u003c\/td\u003e\n\u003ctd\u003eCold-Wound High-Tensile Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Warranty\u003c\/td\u003e\n\u003ctd\u003eLifetime Guarantee\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Tire Size\u003c\/td\u003e\n\u003ctd\u003eClears 33\" Tall Tires\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eMade in the USA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Part Number\u003c\/td\u003e\n\u003ctd\u003e71505\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eVehicle Fitment\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChevrolet Silverado 1500:\u003c\/strong\u003e 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGMC Sierra 1500:\u003c\/strong\u003e 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExcluded Models:\u003c\/strong\u003e NOT compatible with models equipped with factory Magnetic Ride Control \/ MagneRide.
