This SES Suspension Upgrade mounts to the rear control arm of a Ford Maverick. Each laser cut piece of steel is precision cut and powder-coated to ensure a quality fit. Timbren SES kits use hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on your SES kit the harder they work to prevent rear end sag keeping your truck safe and level. Whether you're pulling a trailer or carrying a heavy load in the bed of your truck, SES kits adjust automatically to keep the vehicle level at all times. This SES Suspension Upgrade bolts to the lower control arm. Its unique design ensures superb ride quality ? loaded or unloaded. (There should be a 1/2in. to 1 1/2in. gap between rubber spring and vehicle frame to ensure unloaded ride quality.) Unlike other auxiliary spring systems, the SES Suspension Upgrade guarantees the best of both worlds. This kit is rated at 1800 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 ensure that the load does not exceed the GVWR set by the manufacturer.
