The fully threaded billet aluminum shock body sets ride height for the desired stance and helps fine-tune weight balance, while the single adjustable valving tunes the ride. QA1's American-made lightweight high travel springs use fewer coils and a smaller wire diameter for increased travel, reduced unsprung weight and faster response. It works with factory or upgraded QA1 tubular control arms, bolts in and is made in the USA.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: front coil-over system (Pro Coil)\u003c\/li\u003e\n\u003cli\u003eAdjustability: single adjustable valving\u003c\/li\u003e\n\u003cli\u003eSpring: 10in high travel spring, 650 lb\/in rate\u003c\/li\u003e\n\u003cli\u003eShock body: lightweight billet aluminum, fully threaded\u003c\/li\u003e\n\u003cli\u003eRide height adjustable\u003c\/li\u003e\n\u003cli\u003eWorks with factory or QA1 tubular control arms\u003c\/li\u003e\n\u003cli\u003e100% dyno tested and serialized\u003c\/li\u003e\n\u003cli\u003eBolt-in installation\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003eSold in pairs\u003c\/li\u003e\n\u003cli\u003ePart number: GS517-10650C\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1999 Chevrolet Silverado 1500\u003c\/li\u003e\n\u003cli\u003e2000 Chevrolet Silverado 1500\u003c\/li\u003e\n\u003cli\u003e2001 Chevrolet Silverado 1500\u003c\/li\u003e\n\u003cli\u003e2002 Chevrolet Silverado 1500\u003c\/li\u003e\n\u003cli\u003e2003 Chevrolet Silverado 1500\u003c\/li\u003e\n\u003cli\u003e2004 Chevrolet Silverado 1500\u003c\/li\u003e\n\u003cli\u003e2005 Chevrolet Silverado 1500\u003c\/li\u003e\n\u003cli\u003e2006 Chevrolet Silverado 1500\u003c\/li\u003e\n\u003cli\u003e1999 GMC Sierra 1500\u003c\/li\u003e\n\u003cli\u003e2000 GMC Sierra 1500\u003c\/li\u003e\n\u003cli\u003e2001 GMC Sierra 1500\u003c\/li\u003e\n\u003cli\u003e2002 GMC Sierra 1500\u003c\/li\u003e\n\u003cli\u003e2003 GMC Sierra 1500\u003c\/li\u003e\n\u003cli\u003e2004 GMC Sierra 1500\u003c\/li\u003e\n\u003cli\u003e2005 GMC Sierra 1500\u003c\/li\u003e\n\u003cli\u003e2006 GMC Sierra 1500\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/6b53c08b268bd596bda537d5fbdea2c4.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003c\/p\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eIs this coil-over system adjustable?\u003c\/h5\u003e\u003cp\u003eYes.
