Drop, Single 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 improving ride control and maintaining street comfort. Built with QA1 single adjustable rear shocks and vehicle-specific mounting hardware, it allows you to dial in ride quality while achieving a clean 3–5 inch rear drop. If you are looking to level stance, fine-tune rake, or complete a front suspension upgrade, this kit is a straightforward solution. CONTROLLED STANCE AND ADJUSTABILITY Lowering the rear of a modern truck should not introduce harshness or unpredictability. This kit uses QA1 single adjustable rear shocks to give you control over ride firmness, allowing you to tailor the rear suspension to match how you drive. With a single adjustment, you can tune the rear for daily driving, highway use, or a more composed street feel, helping the truck stay balanced and comfortable after lowering. ENGINEERED FOR STREET USE QA1 engineered this rear drop kit specifically for the weight and suspension characteristics of late-model half-ton trucks. The included rear shock package and mounting components are designed to work together, maintaining proper motion and control at a lowered ride height. Rather than relying on generic components, this system is built to integrate cleanly with the factory suspension architecture of the Silverado and Sierra platform. 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 weekend installs or professional shops alike. It pairs easily with QA1 front suspension components 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, level stance\u003c\/li\u003e\n\u003cli\u003eSingle adjustable rear shocks for easy ride tuning\u003c\/li\u003e\n\u003cli\u003eTunable balance between comfort and control\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\u003c\/li\u003e\n\u003cli\u003eIdeal complement to QA1 front Pro-Coil suspension kits\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv\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\u003eBushing Material\u003c\/strong\u003e: \u003cspan\u003ePolyurethane\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\u003eRDK52633\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: \u003cspan\u003e806990237330\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\u003c\/div\u003e","brand":"QA1","offers":[{"title":"Default Title","offer_id":51775031902486,"sku":"BJGM-RDK52633","price":1124.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0930\/0878\/9782\/files\/0_19-26-silverado-rdk52633_copy_normalized.jpg?v=1787852117","url":"https:\/\/www.cspracing.com\/products\/qa1-rdk52633-leaf-spring-lowering-kit","provider":"Complete Street Performance","version":"1.0","type":"link"}
