{"product_id":"qa1-high-travel-coil-over-spring-qap12ht350b","title":"QA1 High Travel Coil-Over Spring | 2-1\/2in ID, 12in, 350 lbs\/in, Black Powder Coated | 12HT350B","description":"\u003cp\u003eQA1 high travel coil-over springs are wound from specially designed high-tensile chrome silicon alloy spring wire, which allows fewer coils and a smaller wire diameter. The result is a lighter spring with increased travel from the larger gap between coils, reducing unsprung weight and reacting faster for improved suspension response. Careful heat-treating and post-processing extend fatigue life, and the coil design lets the spring compress to coil-bind without affecting spring rate or free height. This spring is ground at both ends for straight, consistent operation, finished in black powder coat, and made in the USA. All QA1 springs carry a lifetime guarantee to remain within 2% of the original free height and rate under normal operating conditions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: high travel coil-over spring\u003c\/li\u003e\n\u003cli\u003eInside diameter: 2-1\/2in (2.5in)\u003c\/li\u003e\n\u003cli\u003eFree length: 12in\u003c\/li\u003e\n\u003cli\u003eSpring rate: 350 lbs\/in\u003c\/li\u003e\n\u003cli\u003eMaterial: chrome silicon alloy spring wire\u003c\/li\u003e\n\u003cli\u003eFinish: black powder coated\u003c\/li\u003e\n\u003cli\u003eEnds: ground square both ends\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003eLifetime guarantee within 2% of original free height and rate\u003c\/li\u003e\n\u003cli\u003ePart number: 12HT350B\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat is the inside diameter of this QA1 high travel spring?\u003c\/h5\u003e\u003cp\u003eThis spring has a 2-1\/2in (2.5in) inside diameter, sized for QA1 coil-over shocks and other coil-over systems that use standard 2.5in ID springs.\u003c\/p\u003e\u003ch5\u003eWhat are this spring's free length and rate?\u003c\/h5\u003e\u003cp\u003eIt has a 12in free length and a 350 lbs\/in spring rate.\u003c\/p\u003e\u003ch5\u003eWhat makes QA1 high travel springs lighter than standard springs?\u003c\/h5\u003e\u003cp\u003eThey are wound from high-tensile chrome silicon alloy spring wire, which uses fewer coils and a smaller wire diameter to cut weight and increase travel while reducing unsprung mass.\u003c\/p\u003e\u003ch5\u003eAre QA1 springs guaranteed?\u003c\/h5\u003e\u003cp\u003eYes.
