Drop, Double Adjustable\u003c\/p\u003e\u003cp\u003eThe QA1 rear drop kit is designed to lower the back of your 2019–2026 Silverado 1500 or Sierra 1500 while giving you precise control over ride quality and suspension behavior. Built with QA1 double adjustable rear shocks and vehicle-specific mounting hardware, it allows independent tuning of compression and rebound. If you want a clean 3–5 inch rear drop with maximum adjustment capability, this kit delivers. CONTROLLED STANCE AND ADJUSTABILITY Lowering the rear of a modern truck should improve how it drives, not introduce harshness or instability. This kit uses QA1 double adjustable rear shocks, giving you the ability to fine-tune suspension response to match your driving style. With independent compression and rebound adjustment, you can tailor rear ride quality for daily driving, highway use, or a more controlled, performance-oriented feel. ENGINEERED FOR STREET PERFORMANCE QA1 engineered this rear drop kit specifically for the weight and suspension geometry of late-model half-ton trucks. The included rear shock package and mounting components are designed to work as a system, maintaining control and predictability at a lowered ride height. Rather than relying on generic rear components, this kit integrates cleanly with the Silverado and Sierra suspension layout to deliver consistent performance and balanced handling. BOLT-IN CONVENIENCE This rear drop kit is designed as a bolt-in upgrade for 2019–2026 Silverado 1500 and Sierra 1500 trucks in both 2WD and 4WD configurations. No cutting or welding is required, making installation straightforward for street builds and daily-driven trucks. It pairs naturally with QA1 front Pro-Coil suspension systems and is an ideal option for dialing in final stance or rake.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e3–5 inch rear drop for a clean, aggressive stance\u003c\/li\u003e\n\u003cli\u003eDouble adjustable rear shocks for independent compression and rebound tuning\u003c\/li\u003e\n\u003cli\u003eMaximum control over rear ride quality and suspension response\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for 2019–2026 Silverado 1500 and Sierra 1500\u003c\/li\u003e\n\u003cli\u003eCompatible with both 2WD and 4WD applications\u003c\/li\u003e\n\u003cli\u003eFully bolt-in design with no cutting or welding required\u003c\/li\u003e\n\u003cli\u003eIdeal complement to QA1 front double adjustable suspension kits\u003c\/li\u003e\n\u003cli\u003eOptional traction bar compatibility for higher horsepower builds\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eBushing Material\u003c\/strong\u003e: \u003cspan\u003ePolyurethane\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eBracket Color\u003c\/strong\u003e: \u003cspan\u003eBlack\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eBracket Material\u003c\/strong\u003e: \u003cspan\u003eSteel\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eBushing Color\u003c\/strong\u003e: \u003cspan\u003eBlack\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eBushings Included\u003c\/strong\u003e: \u003cspan\u003eYes\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eGrade Type\u003c\/strong\u003e: \u003cspan\u003ePerformance\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eInstruction Manual Included\u003c\/strong\u003e: \u003cspan\u003eYes\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eMaximum Drop\u003c\/strong\u003e: \u003cspan\u003e5\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eMounting Hardware Included\u003c\/strong\u003e: \u003cspan\u003eYes\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eShocks Included\u003c\/strong\u003e: \u003cspan\u003eYes\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: \u003cspan\u003eQA1\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: \u003cspan\u003eRDK52634\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: \u003cspan\u003e806990237347\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"QA1","offers":[{"title":"Default Title","offer_id":51775030952214,"sku":"BJGM-RDK52634","price":1338.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0930\/0878\/9782\/files\/0_19-26-silverado-rdk52634_normalized.jpg?v=1787852111","url":"https:\/\/www.cspracing.com\/products\/qa1-rdk52634-leaf-spring-lowering-kit","provider":"Complete Street Performance","version":"1.0","type":"link"}
