You should never exceed the factory-rated maximum GVWR or payload capacity set by GMC.\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 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. However, you must maintain a minimum of 5-10 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, you must strictly adhere to the 150 PSI limit for safe, daily operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How thick is the rubber compared to other brands?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Most standard aftermarket air bags use 3mm to 4.5mm rubber. The SPELAB kit utilizes ultra-thick 5.9mm - 6.0mm multi-layer rubber, offering vastly superior resistance to leaks, abrasions, and blowouts.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will this make my truck ride stiff when it's empty?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Not at all! When you are not towing, simply deflate the air bags to the minimum 5 PSI. 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":"Default Title","offer_id":49196281331963,"sku":"SPBVY0003001","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/0609\/9556\/files\/01_BVY0003001.webp?v=1787123192"}],"url":"https:\/\/www.spelabautoparts.com\/collections\/air-suspension.oembed","provider":"SPELAB","version":"1.0","type":"link"}
