The Timbren FRTTSDE is a helper spring kit: SES - Suspension Enhancement System; Rubber Spring; Frame Mount; 8,000 Pound Load Capacity (Not To Exceed The Gross Vehicle Weight Of The Vehicle).
This SES Suspension Upgrade fits the rear suspension of a Ford F-450 and F-550 cab chassis truck. 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 bed of your truck, our hollow rubber springs adjust automatically to keep the vehicle level at all times. This SES Suspension Upgrade replaces the jounce stop on the frame. Its unique design ensures superb ride quality – loaded or unloaded. (There should be a 1/2 Inch to 1-1/2 Inch 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. 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). This kit is rated at 8000 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.
