SumoSprings® are a patented suspension product designed to enhance load carrying ability, stabilize sway, and improve overall driver control and ride comfort. They are maintenance free, do not leak air, and do not require airlines or compressors. SumoSprings® are manufactured in a variety of heights, diameters and densities to support multiple front and rear applications. They are manufactured from proprietary closed micro-cellular urethane providing a smooth and progressive spring rate with superior damping properties. Every SumoSpring is handmade with care, making each one unique with its own natural characteristics, such as slight color variations and surface bubbles—proof of the craftsmanship that goes into every piece. SumoSprings Solo Kits are a one-piece unit attached on one side used as a replacement/upgrade to factory bump stops.SumoSprings Front for Chevrolet|GMC Silverado|Sierra|Suburban|Tahoe|Yukon 2500|3500, Silverado|Sierra 15002000 (lb) Capacity at 50% CompressionCompress up to 80% of original height with full memory reboundSold as a pair (left and right)Maintenance-freeEnhances load carrying abilityReduces and stabilizes swayImproves overall driver control and ride comfort One-piece unit attached on one side used as a replacement/upgrade to factory bump stopsprogressive spring rate with superior damping propertiesMade from proprietary and patented microcellular urethaneWill not leak or rupture Never load any vehicle beyond the manufacturer’s GVWR Application(s) Summary: Make Model Year Drivetrain Chevrolet Silverado 1500 2001-2003 4 X 2 or 4 X 4 Chevrolet Silverado 1500 HD 2001-2003 4 X 2 or 4 X 4 Chevrolet Silverado 1500 HD 2005-2003 4 X 2 or 4 X 4 Chevrolet Silverado 2500 2001-2004 4 X 2 or 4 X 4 Chevrolet Silverado 2500 HD 2001-2010 4 X 2 or 4 X 4 Chevrolet Silverado 2500 HD Classic 2007-2007 4 X 2 or 4 X 4 Chevrolet Silverado 3500 2001-2006 4 X 2 or 4 X 4 Chevrolet Silverado 3500 Classic 2007-2007 4 X 2 or 4 X 4 Chevrolet Silverado 3500 HD 2007-2010 Chevrolet Suburban 2500 2000-2013 4 X 2 or 4 X 4 GMC Sierra 1500 2001-2003 4 X 2 or 4 X 4 GMC Sierra 1500 HD 2001-2003 4 X 2 or 4 X 4 GMC Sierra 2500 2001-2004 4 X 2 or 4 X 4 GMC Sierra 2500 HD 2001-2010 4 X 2 or 4 X 4 GMC Sierra 2500 HD Classic 2007-2007 4 X 2 or 4 X 4 GMC Sierra 3500 2001-2006 4 X 2 or 4 X 4 GMC Sierra 3500 Classic 2007-2007 4 X 2 or 4 X 4 GMC Sierra 3500 HD 2007-2010 4 X 2 or 4 X 4 GMC Yukon XL 2500 2000-2013 4 X 2 or 4 X 4 th, td { padding-right: 20px; } .product-table-top { display: block; max-width: -moz-fit-content; max-width: fit-content; overflow-x: auto; white-space: nowrap; }
