HOW STRONG ARE MOST OEM LEAF SPRINGS WITHOUT AN ADD A LEAF KIT?

If a new pair of rear leaf springs have recently been added to a vehicle, an add a leaf kit could still be a helpful addition to the framework of the springs, especially if the truck is constantly loaded with heavy items. OEM leaf springs, after all, are merely created to offer an average level of support for a vehicle. If you do in fact carry exceptionally heavy loads on a regular basis, it's necessary to boost the strength of the vehicle's suspension system.

The reasons why automakers opt for middle-strength springs is to offer a balance between strength and flexibility. If the springs are too hard, you will have a very uncomfortable ride as the vehicle encounters the various bumps along the roads you might take to any given destination. Likewise, a set of leaf springs that are too soft will lack the strength to support much of anything in back.

In the former situation, you and your passengers could wind up with back aches after a ride in the vehicle. In the latter situation, the truck wouldn't be useful for much of anything. As such, automakers play it safe by equipping vehicles with leaf springs of middle-grade strength.

With the addition of helper springs or an add a leaf lift kit, you can strike a fine balance between medium and heavy strength for the rear leaf springs of your vehicle. When the vehicle is unloaded, it will simply display a healthy back-lift when viewed from afar on an even parking surface. When the vehicle is fully loaded, the leaf springs will have the strength to handle the extra weight.
