SuperSprings International (SSI) is a trusted American suspension solutions company with over 25 years of engineering and innovation in the automotive aftermarket.
Originally founded in 1996 in Carpinteria, California by Cathi Lamberti, the brand began with a simple mission: to help vehicles work better, drive safer, and last longer under load. From humble beginnings with just a handful of employees in a small warehouse, SSI has grown into a globally recognised name — expanding to new facilities and markets while continually refining its products and technology.
Over the years, SuperSprings has introduced numerous industry-leading suspension enhancements like airless load support systems (SumoSprings), self-adjusting helper springs, heavy-duty coil upgrades, and advanced sway control products that improve stability, ride comfort, and load-carrying performance for trucks, SUVs, vans, RVs and trailers.
Headquartered in Southern California with additional operations across the U.S. and internationally, SSI remains committed to its core values of innovation, durability, and maintenance-free performance that empower drivers wherever the journey takes them. Devon 4x4 is a distributor of SuperSprings, based in the UK, shipping worldwide.
