Built to clear wheels up to 28 inches, it replaces the factory suspension on all four corners with single-adjustable coil-overs, giving you independent control over ride height and damping without cutting, welding, or fabrication.\u003c\/p\u003e\u003cp\u003eUp front, the QA1 Pro Coil single-adjustable coil-over system lets you raise or lower the car up to 2 inches from stock, paired with tie rod adjuster sleeves for proper alignment after the ride height change. In the rear, a matching single-adjustable Pro Coil kit works alongside adjustable upper and lower trailing arms that re-center the axle in the wheel well - critical for tucking large-diameter wheels correctly - with a rear range from 0.5 inch above stock to 2 inches lower than stock.\u003c\/p\u003e\u003cp\u003eEvery component ships powder coated and ready to install, and the kit includes a thrust bearing kit and spanner wrench kit so you can dial in your exact stance in minutes, then fine-tune shock firmness with a twist of the adjustment knob. It's built for donk, box, and bubble-style big wheel builds where a clean, adjustable stance and a smoother ride matter as much as the look.\u003c\/p\u003e\u003cmeta name=\"description\" content=\"Upgrade your 1977-1990 Chevy Caprice or Impala with the QA1 Big Wheel Kit for adjustable ride height and enhanced performance.\"\u003e\u003cmeta name=\"keywords\" content=\"QA1 big wheel suspension kit, Chevy Caprice suspension upgrade, adjustable coil-over system for Impala, high-performance suspension for GM B-Body, Level 1 suspension kit for 1977-1990 Chevy, big wheel clearance suspension kit, single-adjustable shocks for Chevy, powder coated suspension components, rear trailing arms for big wheels, premium automotive performance parts\"\u003e","brand":"QA1","offers":[{"title":"Default Title","offer_id":53499712831807,"sku":"QAPBW01-GMB5","price":2741.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/7308\/9343\/files\/1d71bd1b73fa4d1df76128a43884e11bL.jpg?v=1780440331","url":"https:\/\/wcaperformance.com\/products\/qa1-77-90-gm-b-body-level-1-big-wheel-kit","provider":"WCA Performance","version":"1.0","type":"link"}
