SumoSprings are not made from rubber. They are a progressive spring with a very soft initial engagement. That means that as more weight added, the harder they get and more they push back, providing support and control when you need it without affecting the factory ride when unloaded. These are a suspension enhancement built to create a better journey. Manufactured from our micro-cellular polyurethane, they are designed to reduce rear-end sag, decrease vibration, stabilize sway and soften harsh rebounds.Features & BenefitsRequires No MaintenanceEnhances Load Carrying Ability5600 Pounds Capacity At 50 Percent CompressionReduces And Stabilizes SwayImproves Overall Driver Control And Ride ComfortCompress Up To 80 Percent Of Original Height With Full Memory ReboundOne-Piece Unit Attached On Top And Bottom Allows Up To 50 Percent Expansion Of Original Body HeightProgressive Spring RateMade From Patented Micro-Cellular Urethane; Leak-Proof Air Spring2008 Ford F532009 Ford F532011 Ford F532012 Ford F532013 Ford F532014 Ford F532015 Ford F532016 Ford F532017 Ford F532018 Ford F532020 Ford F532021 Ford F53
