Step 1: Choose Your Vehicle Make

What Are Helper Springs?

Helper springs are an aftermarket product that can be attached to your suspension to take the pressure off the original springs that came with your vehicle. They work by keeping the back of your truck as level as possible by creating a stiffness that can stand up to whatever you can put in the back. There are several types of helper springs, and which one you choose is dependent on your vehicle and the way you use it to haul your larger loads.

What Does a Helper Spring Do?

First and foremost, helper springs keep the back of your vehicle level. Even the most heavy-duty of truck beds have a tendency to sag when they're loaded up with gear, and this will noticeably affect your truck's stability.

You may see that not only does your vehicle dip down in the back, leaving you open for damage should you go over a large bump or hit a particularly nasty pothole, but that you no longer feel as in control as you once did with your steering.

The handling, brakes, and steering can all be compromised when your truck is under this type of pressure, which not only puts the driver at risk, but also other cars on the road. Your tires will start to show wear much faster, and may start to form uneven patterns of baldness. At the very least, it means the vehicle has to work much harder just to function, and you will start to see the strain of the weight add up when it comes to repair bills and maintenance costs.

When Should I Use a Helper Spring?

You should consider adding a set of helper springs if you notice any of the following conditions when you are towing a trailer, or hauling a heavy load:

  • The tow vehicle is not level with the trailer
  • Your rear truck springs sag
  • Your truck does not ride level
  • The headlights on your vehicle no longer light up the road in front of you
  • You feel extra sway when changing lanes, or turning corners. Your steering feels "loose"

No, helper springs are not designed to lift your truck, but they are designed to level out the back of your truck. A leaf spring helper appears to lift the truck because it eliminates the sag commonly seen when a truck is loaded to its full capacity, but it's really only keeping the truck at the level it would be if there was less weight in the back. They will help maintain stock ride height but not go over it. If you are looking for a lifted truck, we recommend a lift kit or leveling kit.

The GVWR is set in stone by the maker of your vehicle, and no amount of helper springs will change this. However, a helper spring can decrease sag by up to 2 inches or more in a vehicle. By leveling out the vehicle, all the components in your truck are working far less to carry a lot more. This means that your vehicle will function as if it was carrying a lot less than it is. They will help you to tow up to GVWR, but no aftermarket products can increase the GVWR.

No, almost all of them are considered an install and forget products. Once you install them, there is nothing further you need to do. It is always recommended to check on them occasionally, and verify your bolts are tight, but other than that they are maintenance free. Air helper springs require that you maintain a minimum air pressure.

Yes, it is very common to use them with sway bars. We have numerous customers with heavy trailers or motorhomes that use both products to eliminate sway.

This will depend on which kit you are wanting to use and how your truck is lifted. Some of the manufacturers offer additional spacers or taller springs to compensate for the lift. Feel free to call us at 1-800-358-4751 and we can see what is available for your specific lift.

How difficult they are to install will depend on which part you choose and the type of vehicle you have. Installing helper springs is typically something that can be done in your garage over the period of a few hours and do not require professional installation. Some of the kits can be installed in much less time, but your experience, type of jacks, etc. you have will influence the time needed. We list the installation instructions on our website and recommend reviewing them to see what the installation requires.

Truck leaf springs are a critical part of your suspension and if they are shot, we recommend replacing them. Helper springs are designed to work alongside a suspension that is in good working condition.

A leaf spring helper or coil spring helper will not raise your truck, so the factory shocks will work just fine. If your shock absorbers are worn, now would be a good time to replace them. We recommend Bilstein shocks for anyone that tows or hauls, they are top of the line and worth the few extra dollars over budget shocks.
