RAM ProMaster City Helper Springs
Heavy-Duty Helper Springs for RAM ProMaster City
The RAM ProMaster City is a compact cargo van known for its efficiency, maneuverability, and payload capacity—making it a top choice for contractors, delivery services, and fleet operators. But when fully loaded with tools, inventory, or equipment, the factory suspension can sag, compromising ride quality, steering stability, and ground clearance.
That’s where MAD Heavy-Duty Helper Springs come in.
The Problem: Rear Sag and Poor Ride Comfort
When your RAM ProMaster City is loaded beyond normal daily use, you may notice:
- Rear suspension sagging
- Reduced ground clearance, especially over speed bumps and loading docks
- Less steering control due to reduced front axle pressure
- Premature wear on shocks, bump stops, and tires
- Increased driver fatigue from constant steering corrections
