When truck owners look to optimize the payload capacity of a given vehicle, they’ll often assume that the most practical option is to change out the leaf springs for a stronger set. The trouble is, this can be needlessly costly and wasteful if the OEM rear leaf springs are in good condition and have years of life left in them. The better option is to boost the strength of the pre-existing leaf springs with the installation of add a leaf kits.
With the added strength of the extra leafs and the extra bit of lift an add a leaf kit provides, a truck can live up to its full payload capacity. How much lift does an add a leaf give? Overall, add a leaf kits increase the rear lift of a vehicle anywhere from one to three inches.
WHAT ARE ADD A LEAF KITS?
There are some trucks that need additional leaf springs to improve the load capacity. When a truck is slumping at the back while loaded, it’s an obvious sign the vehicle is not living up to its carrying capacity.
Things shouldn’t be this way. A truck is built to carry heavy loads, and any truck should be more than capable of carrying a full load without slouching at the rear. With the addition of an extra leaf into each rear leaf spring, inches of lift can be added to the back that will keep the vehicle horizontal, even when the back is full.
The process of adding a leaf to the rear of a vehicle is similar to that of a leaf spring upgrade. You are giving the rear of the truck additional support to handle full loads in all types of driving situations. For this very purpose, a variety of add a leaf kits are available on the market for a vast range of trucks. For example, add a leaf kits that are manufactured for the makes and models of Dodge and Chevy trucks are designed to elevate the spring capacity of said vehicles to the level of an HD spring.
For the purpose of adding leafs to the leaf springs under a vehicle, there are two types of products on the market which are add a leaf kits and helper springs. With add a leaf kits, the leaf or leafs are added between the pre-existing leaf springs and rebound springs at the rear axle under a truck. With helper springs, the additional springs are mounted onto the pre-existing leaf springs. Helper springs are easy to install and can be a good option for anyone who seeks an inexpensive solution to a slumped vehicle rear.
The major difference between helper springs and add a leaf lift kits is that the former offers a constant and progressive rate, whereas the latter is limited to merely a constant rate. With the progressive rate, the effects of the helper spring are activated when the truck is loaded in back. As the backload gets heavier, the rate of the helper spring progresses to accommodate the extra weight. Essentially, the helper spring increases support on an as-needed basis for the loads a driver carries on a given day.
