When you drop a heavy 5th-wheel RV on the hitch or load the bed with thousands of pounds of equipment, the rear end inevitably sags. This \"truck squat\" is more than just an eyesore—it’s a major safety hazard. It lifts weight off your front tires, causing unresponsive steering, longer braking distances, aggressive trailer sway, and headlights that blind oncoming traffic.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLevel Your Load with SPELAB's 7,500-LB Heavy-Duty Air Suspension.\u003c\/strong\u003e\u003cbr\u003eEngineered for the most demanding hauling and towing applications, this premium air helper spring kit acts as a muscular support system for your factory suspension.

You should never exceed the factory-rated maximum Gross Vehicle Weight Rating (GVWR) or payload capacity set by Ford.\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: Because there is no internal bumper, 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 an extreme 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 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\u003cstrong\u003eQ: How thick is the rubber compared to standard air bags?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Most standard aftermarket air bags use 3mm to 4.5mm thick 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---tab Shipping \u0026amp; Returns---\u003c\/p\u003e","brand":"SPELAB","offers":[{"title":"Default Title","offer_id":49198333264123,"sku":"SPBVY0002001","price":329.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/0609\/9556\/files\/01_BVY0002001.webp?v=1787190141","url":"https:\/\/www.spelabautoparts.com\/products\/rear-air-suspension-kit-for-2011-2016-ford-f250-f350-super-duty-spelab","provider":"SPELAB","version":"1.0","type":"link"}
