Reduces Sway and Instability when Towing and Hauling

When you add a snow plow system, heavy grille guard, or big bumper with a winch to your 2005-2025 F450 or F550, you may notice that your front end has sagged a bit due to the extra weight. If you want to get your truck back to a more level stance after you’ve added a bunch of front weight, you’ll need SuperSprings Front SumoSprings. Capable of holding up to 4000lbs 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 4000lb 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 so that you get vastly improved stability without hassles.

Unique Microcellular Urethane Springs with Brackets and Spacers

The 4000lb SumoSpring Kit includes a pair of mircocellular urethane springs, brackets, and spacers work together to give your F450 or F550 a vastly improved loaded ride over stock. Each spring features a black color that denotes its -47 urethane density that can handle 4000lbs of load at 50% compression and holds enough air to handle heavier loads than the blue SumoSprings while still giving your truck a nice ride. 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. Fitment: 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025 F450 & F550
