Reduces Rear Sag, Sway, and Instability when Towing and Hauling

Sway and sag are always a threat when you're towing with your 2011-2016 F250 or F350, even if you're well shy of your GVWR or GCWR. To help minimize sway and sag, SumoSprings has developed with 4600lb SumoSpring Kit. Capable of holding up to 4600lbs of load, the SumoSpring System consists of drop-in extended bump stops made out of specialized microcellular urethane material that gives you the load support of a traditional air spring, but with a much better street ride and without the hassle of filling up the springs with air every time you load up your Super Duty or trailer. The 4600lb SumoSprings Kit is extremely easy to install and drops right into the factory bump stop location in only a matter of minutes. The SumoSpring keeps load off your truck's suspension, minimizing sag and rear-end roll so that you get vastly improved stability without hassles.

Unique Microcellular Urethane Springs with Brackets and Spacers

The 4600lb SumoSpring Kit includes a pair of mircocellular urethane springs, brackets, and spacers work together to give your F250 or F350 a vastly improved loaded ride over stock. The springs can handle 4600lbs of load at 50% compression, allowing you to haul heavy loads without experiencing a big hit in ride quality. The SumoSpring features a full memory rebound after compression so that you don't have to worry about resetting the spring or losing load capacity over time. The patented microcelluar urethane construction provides your Super Duty build with a smooth, progressive spring rate with excellent damping characteristics in both loaded and unloaded applications. These springs are made right here in the USA.
