This SES Suspension Upgrade fits the front suspension of a Ford F-350, F-450 & F-550 cab & chassis truck. Each laser cut piece of steel is precision welded and powder-coated to ensure a quality fit. We’ve engineered our hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs (weight from a snowplow or heavy aftermarket accessories – such as a steel bumper) the harder they work to prevent front-end sag.
We recommend Severe Service kits be used with a slide-in camper or salt spreader. In fact, any application that requires maximum stability (reducing roll and sway) calls for a Severe Service upgrade. (Click here for more info on Severe Service recommendations)
FF550SDH replaces the bumpstops on the front suspension of the 2005-2020 Ford F-350 Super Duty, F-450 Super Duty and F-550 Super Duty cab and chassis models.
This kit is rated at 11,000 lbs capacity. Even though you’re increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.
