Suspension Rubber Helper Spring Kit

This SES Suspension Upgrade fits the rear suspension of a Ford F-350 pickup truck & cab chassis. Each laser cut piece of steel is precision bent and powder-coated to ensure a quality fit. Timbren engineered their 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, this 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 ½” to 1 ½” gap between rubber spring and frame to ensure unloaded ride quality.) Unlike other auxiliary spring systems, the SES Suspension Upgrade guarantees the best of both worlds.

SES Suspension Upgrade replaces the bumpstops on the rear suspension of the 1999-2004 Ford F-350 Super Duty 2WD and 4WD cab and chassis models and the 2005-2016 Ford F-350 Super Duty 2WD and 4WD pickup truck models.

This kit is rated at 8600 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 SES – Suspension Enhancement System – upgrades improve your suspension with:
  • More Safety
    When extra weight makes your vehicle squat in the back, the front-end lifts up reducing traction on the front tires. Not only that, if the front is too high your headlights will shine up into the eyes of oncoming traffic instead of pointing down on the road ahead.

    Timbren SES upgrades are designed to keep your vehicle level at all times. This will increase traction on the front tires, improve overall steering and keep your headlights pointing down on the road where they belong.


  • More Stability
    • If extra weight makes your vehicle top-heavy, you’re going to experience body roll and sway. There’s nothing more challenging than trying to keep your vehicle moving on a straight path when the load is unstable.

      Timbren SES upgrades offer you more stability and peace of mind by eliminating suspension sag and reducing body roll & sway.


  • More Comfort
    • Too much weight can cause your vehicle to bottom out if you’re driving over roads that are bumpy and rough. All this road shock will compromise an otherwise comfortable ride.

      Improve your ride quality by installing Timbren SES upgrades, guaranteed to provide a softer, smoother ride… empty or loaded.
