Does your Ford E-150/250/350/450 van or Mercedes-Benz Sprinter 2500/3500 sag in the rear when you load it up with gear or hook up a trailer? That sag isn't just annoying – it can affect handling, braking, and put extra strain on your suspension. This helper spring kit (part number 106-47, also replaces SSF-106-47) is a simple and effective solution. These are heavy-duty, industrial-grade air spring bladders that you install alongside or in place of your existing coil springs (depending on your setup). When you're empty, they barely do anything. But when you add weight or start towing, you can use a small onboard air compressor (often sold separately) to inflate them. As they fill with air, they push against the axle, providing extra support to level out the vehicle and restore proper ride height. This means better stability, reduced body roll, and less headlight glare for oncoming traffic. They're a popular upgrade for work vans, RVs, and campers. The kit includes two helper springs. Installation requires some mechanical knowledge. Check your specific year and model for compatibility, and consider if you need a separate air source and control system. Get ready to haul heavy with confidence!
