Timbren 1999 Ford E450 Econoline 1996-2022 E-450 SuperDutySES Suspension Enhancement System Rear Kit FERSD

Description Feature: Eliminate Vehicle Squatting & Sagging Cushion Road Shocks Improve Handling Satisfaction Guarantee Lifetime Warranty Description: This SES Suspension Upgrade fits the rear suspension of a Ford E-450 E-550 van. Each laser cut piece of steel is precision bent 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 the harder they work to prevent rear end sag. Whether you’re pulling a trailer or carrying a heavy load in the back of your van, our hollow rubber springs adjust automatically to keep the vehicle level at all times. This SES Suspension Upgrade replaces the jounce stop on the axle. Its unique design ensures superb ride quality – loaded or unloaded. (There should be a ½” to 1 ½” gap between rubber spring and axle 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 5600 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.Timbren Suspension Kits (SES Kits) are designed to enhance the suspension of your vehicle. Easiest to use: Rubber cushions absorb road shocks and automatically adjust to uneven loads or road conditions. Easiest to maintain: There are no airlines or fittings to allow leaks. Simply bolt the kit on and you are set for a lifetime of trouble free suspension. Easiest to install: There are no holes to drill, no airlines to route and SES Kits can be installed in a matter of minutes using basic hand tools. The softer ride quality of todays trucks and the mediocre suspensions found on most trailers can cause excessive trailer sway, instability and suspension settling. Timbrens high performance suspension packages will ensure added safety and peace of mind.
