RAM ProMaster Hellwig Helper Spring


What is it made of?

The helper springs have been made of very strong steel. The design allows the spring to reduce sagging from the rear end. It also adds strength to the system so that it can withstand a load of 2000 lbs.

It sounds sort of heavy and hard to adjust.

Actually, the manufacturer has told us that this spring is easy to adjust so that you can manage your loads better.

What is this thing supposed to do?

The Hellwig EZ-990 helper spring helps bring spring rate and stability to your Dodge Promaster.

If they are designed with this steel, then does it mean that effects the overall strength of the part?

It actually does. The steel helps the spring stop rear end sag. It also has the strength to allow the spring to handle a load capacity of 2000 pounds.

How does this install?

We were told that you mount them to the factory axle U-bolt plates.

Is there anything else I should know about these that is sort of special?

They have given the springs a heat-treatment. The heat treatment allows the springs to be even more durable and gives them extra strength than if they had not heat-treated them. It should help you absorb bumps and keep your ride much more level and give you a greater sense of safety.

I can adjust these springs independently if I need to do so?

Yes. You are correct. They can be adjusted asymmetrically for your needs.

Does this come with a warranty?

Yes. The manufacturer has a lifetime warranty.
