✅ Compatible with U.S. Sprinter Models:
Our helper spring kits are designed for U.S.-spec Sprinter vans, including:
- Sprinter 1500 / 2500 / 3500 / 4500 Cutaway
- Cargo, Passenger, and Crew configurations

- Rear-wheel drive (RWD) only — not compatible with AWD models
- Popular with upfitters like Winnebago, Airstream, and independent RV builders
🧰 Why Add Helper Springs to Your Sprinter?
Factory suspension setups are not always optimized for heavy or continuous loads. Especially when converting to a camper, transporting tools, or towing, the rear axle can sag or feel unstable.
Helper springs add progressive support to the rear suspension — engaging more as the vehicle becomes more loaded — without affecting unloaded ride quality.
✅ 4 Reasons to Install Helper Springs on Your Mercedes Sprinter
1.
Prevent Rear Sag Under Load
Whether you’re hauling cargo, towing, or driving a loaded camper, helper springs keep the van level and prevent bottoming out.
2.
Improve Handling and Safety
Less sway and bounce when cornering or driving in crosswinds — essential for high-roof vans and heavy conversions.
3.
Protect Factory Suspension
Reduce wear on OEM springs, shocks, and bushings, extending their lifespan and maintaining performance over time.
4.
Ideal for Vanlife & Commercial Use
Perfect for RV builds, mobile workshops, and delivery vans carrying consistent or heavy loads.
