It uses a 2.5 inch spring and an included hardware kit for quick ride height adjustment, and a single knob stiffens or softens the ride for street use. This shock has a compressed height of 12-5\/8in and an extended height of 18-3\/4in with bearing eyelet top and bottom. Every Proma Star shock is made in the USA, dyno tested, and backed by a Limited Lifetime Warranty when registered before installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSeries: QA1 Proma Star\u003c\/li\u003e\n\u003cli\u003eType: Single-adjustable coil-over shock\u003c\/li\u003e\n\u003cli\u003eMounting: Custom mount, Bearing eyelet top and bottom\u003c\/li\u003e\n\u003cli\u003eSpring: Accepts 2.5in coil-over spring (sold separately)\u003c\/li\u003e\n\u003cli\u003eCompressed height: 12-5\/8in\u003c\/li\u003e\n\u003cli\u003eExtended height: 18-3\/4in\u003c\/li\u003e\n\u003cli\u003eMade in the USA, dyno tested and serialized\u003c\/li\u003e\n\u003cli\u003ePart number: DS601\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat vehicles does the QA1 Proma Star coil-over shock fit?\u003c\/h5\u003e\u003cp\u003eIt is a custom-mount shock made for custom chassis and suspension projects rather than one vehicle, so it fits any build where the compressed height, extended height, and mounting style match.\u003c\/p\u003e\u003ch5\u003eIs this shock single or double adjustable?\u003c\/h5\u003e\u003cp\u003eIt is single adjustable.
