🛠️ Why SumoSprings?
Factory suspension alone often isn’t enough for vans loaded with gear or converted for adventure. When hauling heavy cargo, the rear of your van sags, affecting headlight aim, front wheel traction, and overall safety. SumoSprings step in to absorb road shocks, distribute load weight, and maintain a level ride—all while helping to preserve your van’s OEM suspension components.
