Bushing Mount 10.125in\/14in Aluminum | DD402","description":"\u003cp\u003eThe QA1 Proma Star Series coil-over shock absorber brings coil-over performance to a wide range of custom chassis and suspension builds where a direct-fit shock is not available. This double adjustable model uses a bushing mount and measures 10.125in collapsed and 14in extended. Independent compression and rebound adjustment let the shock move from the street to the drag strip or road course. The poly bushing mount includes sleeves and helps reduce noise, vibration, and harshness. The included hardware kit allows quick ride height adjustment, and the shock accepts a 2.5in diameter coil-over spring in the appropriate length and rate, sold separately. Each unit is machined from aluminum, dyno tested, serialized, and built in the USA.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSeries: QA1 Proma Star coil-over\u003c\/li\u003e\n\u003cli\u003eDouble adjustable with independent compression and rebound tuning\u003c\/li\u003e\n\u003cli\u003ePoly bushing mount with included sleeves to reduce NVH\u003c\/li\u003e\n\u003cli\u003eCollapsed length: 10.125in\u003c\/li\u003e\n\u003cli\u003eExtended length: 14in\u003c\/li\u003e\n\u003cli\u003eAccepts a 2.5in diameter coil-over spring (sold separately)\u003c\/li\u003e\n\u003cli\u003eAluminum body, dyno tested and serialized\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003eLimited Lifetime Warranty (register at QA1.net\/warranty before installation)\u003c\/li\u003e\n\u003cli\u003ePart number: DD402\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat spring does the QA1 Proma Star coil-over use?\u003c\/h5\u003e\u003cp\u003eIt accepts a 2.5in diameter coil-over spring in the length and rate suited to the application.
