    Timbren SES suspension upgrade kits are an innovative solution to the problem many truck owners face: how do you balance towing strength with daily driver comfort?

    The Timbren SES suspension upgrade kit adds Timbren's patented Aeon rubber springs to your existing suspension, improving suspension performance under all heavy loads.

    In the old days, a pickup truck came with stiff, strong springs designed to be abused for years by hard farm or work use. The downside was that those trucks rode like covered wagons. Today's trucks ride better than most cars, but they sometimes come up short when it's time for hard work, sagging embarrassingly when you tow a heavy load or hold a snow plow. Timbren SES kits fix this problem without ruining your truck's ride.

    The Timbren SES uses a thick rubber spring to add thousands of pounds of leveling strength to your truck, van or SUV's suspension. Timbren SES kits bolt to one side of your truck's suspension (either the bottom or the top) and have 1/2" to 1-1/2" of clearance when unloaded. This means the SES will not impact your truck's ride until it is needed.

    Timbren SES rubber springs are not air springs. They cannot be punctured or popped and require no adjustments, making them perfect for offroad or work trucks.
