Truck Leaf Springs And Hauling: What You Need To Know
In a truck, the leaf springs are the main component keeping the wheels moving smoothly over bumps and potholes without transferring the jarring to the body of the truck. This makes your ride smoother and easier on your passengers, as well as on any type of load that you may be carrying.
Without leaf springs and the rest of your vehicle suspension, your drive would be extremely uncomfortable. However, not everyone realizes that leaf springs come in many different load capacities for the same type of truck. If you're going to use your truck to haul heavy loads, then you need to know what weight your leaf springs can hold so that you don't exceed the limit they can carry. Options are available to improve the carrying capacity of the leaf springs and suspension, but knowing how large your biggest load will be is an important first step.
