Hellwig Helper Springs

All Hellwig springs are 100% American Made. They are manufactured with heat treated alloy spring steel in their California factory.

This will depend on the tongue weight of your trailer, how much you are putting in the back of your pickup and the current condition of your suspension. Hellwig offer helper springs from 500 lbs. capacity on up, so this will vary from specific case to case. If you know you have a tongue weight of 750 lbs. and have some sag, we would recommend a kit with a slightly higher capacity to cover the weight and have little extra. In this case a 1,000 lbs. kit may be adequate and a 2,500 lbs. kit would be overkill.

They will have very little affect on the ride when you are not loaded. They sit on top of your leaf springs and you can tighten or loosen the u-bolts to adjust the preload on them. This will reduce any stiffness in the ride when not loaded. If you are consistently hauling heavy loads and keep your preload to the maximum, you will have some stiffness when you are not loaded. This can be reduced by adjusting the u-bolts.

Yes, they include all the necessary mounting hardware. If you purchase a Hellwig helper spring from us, it will have all the hardware required for the installation. They are either included in the kit or bundled together as noted by the part number on our site. If a mounting kit is bundled you will see it at the end of the part number with a dash, ex. 2515-25250. This will include the main helper spring kit, part 2515 and the 25250 mounting kit.

They are sold in sets and will include everything needed to install on both the driver and the passenger side of the vehicle. One kit will do one vehicle.

No. When the helper spring is installed, there is no increase in the bed height of your truck when empty. They will prevent it from going down, but will not raise it up.

The polyurethane stability blocks in the Pro Series are used primarily to place tension between the Hellwig Pro Series and the vehicles main leaf. The spacer keeps the u-bolt and cross bar assembly tight and will prevent noise from lack of tension. They also act as a stabilizer to resist body roll in corners or high wind.

They do not. There are too many other factors that manufactures use to determine the ratings. They will level your truck, make for a more stable, safer ride, but will not change the tow rating.

Yes, they are designed for sagging leaf springs, and will prevent it when towing a travel trailer.

Hellwig overload springs and their components are warranted for the life of the vehicle these products are originally installed upon.

The leaf springs are a critical part of your trucks suspension. If they are bad, we recommend replacing them before putting a helper spring on top of them. Helper springs are designed to work with your leaf spring, but will not replace or repair them. The added support will help, but they work best with leaf springs that are in good working condition.
