The .5 part numbers are sold as individual single-side units - order two for a complete pair. Each side adds 2,500 lbs of load-leveling ability (4,400-5,000 lbs per pair depending on rating source), cutting rear-end sag and body roll under load without hardening the unloaded ride, thanks to the patented roller-shackle design that only engages as weight is added. Shot-peened SAE 5160H steel, maintenance-free, typical install about an hour with the included mounting kits. Chassis cab models only - do not use on pickup models - and never load beyond the truck's GVWR.\u003c\/p\u003e\u003cp\u003eBrand: SuperSprings\u003c\/p\u003e","brand":"SuperSprings","offers":[{"title":"Default Title","offer_id":67715873341589,"sku":"SSISSA17.5","price":372.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/5995\/6373\/files\/SSISSA17.5.jpg?v=1792201393","url":"https:\/\/turn4diesel.com\/products\/supersprings-ssa17-5-helper-spring-single-side-2-500-lb-capacity-ford-f-450-f-550-super-duty-chassis-cab-1999-2021","provider":"Turn4Diesel","version":"1.0","type":"link"}
