As a result, installing the Add-A-Pack on an F350 may actually make the rear suspension stiffer, potentially even stiffer than the stock setup. For this reason, the Progressive Add-A-Pack is not recommended for an F350. To achieve optimal ride quality, we highly recommend installing Carli Full Replacement Leaf Spring Packs\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carli Suspension","offers":[{"title":"Default Title","offer_id":43289024921689,"sku":"CS-FPAP-11","price":1369.44,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8030\/9593\/files\/2017-2024-Powerstroke-Passenger-Side-Add-A-Pack-Leafs-AS-FPAP-17-LVL-PASS-Add-A-Leaf-Carli-Suspension-Canada.jpg?v=1778536452","url":"https:\/\/dirtygarage.com\/products\/2011-2016-super-duty-4x4-progressive-add-a-pack-kit-cs-fpap-11","provider":"Dirty Garage","version":"1.0","type":"link"}
