Taking The Sag Out Of Your Truck's Suspension
Posted on: 1 December 2018
Modern trucks are versatile vehicles that offer you the option of hauling things in the bed while still letting you have a nice ride. While they look great, there are some trucks on the road that suffer from a sag in the rear of the truck. The springs are too light for the truck, or they have been overloaded. There is a simple solution for most trucks that is not hard to install.
Rear Sag and Leaf Springs
If the rear of your truck has leaf springs on it, installing a leveling kit that provides a helper spring is the best option. Some kits give you a lift block of aluminum to mount between the springs and the axle, but they do not help reinforce the springs and can cause spring wrap that will further weaken the springs. The helper spring is installed in the spring pack and adds additional stiffness to the springs as well as lifting the rear slightly. You can contact a company like Bottomless Suspension for more help with leveling kits.
Coil Spring Level Kits
For trucks that use a coil spring suspension, a leveling kit typically uses a spacer made from rubber that is installed between the spring and the mount on the body. Coil spring suspensions use a track bar and control arms to keep the axle from moving around under the truck, so adding a spacer does not hurt as long as it is not too tall. Most leveling blocks are only 1/4 to 1/2 inch tall and do not pose a problem.
Front Leveling Kits
While it is possible to have a truck with some spring sag in the front suspension, it is not very common. Installing heavy bumpers or a winch to the front of the truck can contribute to front spring sag on some trucks because of the added weight. There are companies out there that make spacer kits for the front suspension as well as rear kits and some that offer kits with that do both to balance the suspension and height of the truck front to rear.
Abnormal Spring Sag
If your truck is only sitting low on one side or the other, check the suspension and springs for damage. It is not normal for only one side to sag and could be a sign of a broken spring or other damage to the suspension of the truck. If you are not comfortable inspecting the suspension, take the truck to a mechanic and have it checked. They can check all the components in the suspension system for you and let you know what is causing the problem.
