You should never exceed the factory-rated maximum Gross Vehicle Weight Rating (GVWR) or payload capacity set by Chevrolet.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do these bags have an internal jounce bumper?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No. These air springs are intentionally designed without an internal jounce bumper. This allows for a larger internal air volume, which results in a smoother, less jarring ride quality when towing. Note: You must maintain a minimum of 5 PSI in the bags at all times to prevent them from bottoming out and tearing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the maximum pressure I can run?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e The recommended maximum operating pressure is 150 PSI. While these heavy-duty bags are tested to withstand a burst pressure of 435 PSI (3 MPa), you must strictly adhere to the 150 PSI limit for safe, daily operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will this fit my GMC Sierra 1500?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes. The 1999-2018 Chevy Silverado 1500 and GMC Sierra 1500 share the identical GMT800 chassis platform, meaning this kit will bolt up perfectly to either truck.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will this make my truck ride stiff when the bed is empty?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Not at all! The beauty of adjustable air springs is that you can deflate them to the minimum 5 PSI when you are not hauling. Your truck will ride smoothly on its factory suspension just like it did before the installation.\u003c\/p\u003e\n\u003cp\u003e---tab Shipping \u0026amp; Returns---\u003c\/p\u003e","brand":"SPELAB","offers":[{"title":"1999-2006","offer_id":49196930990331,"sku":"SPBVY0001001","price":259.0,"currency_code":"USD","in_stock":true},{"title":"2007-2018","offer_id":49196931023099,"sku":"SPBVY0001002","price":259.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/0609\/9556\/files\/01_BVY0001001.webp?v=1787139126"}],"url":"https:\/\/www.spelabautoparts.com\/collections\/duramax-suspension-lift.oembed","provider":"SPELAB","version":"1.0","type":"link"}
