RAM ProMaster 1500 / 2500 / 3500 · 2014–present (FWD)
RAM ProMaster Helper Springs — Ride taller, drive safer.
MAD helper springs keep your ProMaster level and controlled with real payload on board — service vans, camper builds, and everything in between.

Prices in USD. Prices include tax and local import fees; exclude fitting. TÜV approval unless noted.

How it works
A second spring supports the main leaf (rear) or reinforced coils replace the OE fronts. Support ramps up with load — so empty ride stays comfortable.
- Rear: helper springs sit beside the main leaf
- Front: coil swap inside strut assembly
- No compressors, valves, or air lines
What you’ll feel
- Reduced sag with payload
- Less roll in turns & crosswinds
- Sharper steering (front kits)
- More control, less upkeep
Why MAD vs. air
- Predictable spring rate, no leaks
- Simple bolt-on hardware
- TÜV part approval & fitting manual
- Pairs well with KONI FSD when needed

FAQ
Will helper springs change my GVWR or towing?
No. They improve support and control but do not alter manufacturer ratings.
Are KONI FSD shocks required?
Not required. They pair well with constant-load builds for comfort and control (see SD-kits).
Do I need an alignment?
Rear installs typically do not. Front spring installs should be followed by a wheel alignment.
