Suspension leveling kits work to increase ground clearance by altering the height of a vehicle's suspension system. These kits typically consist of spacers or blocks that are installed between the vehicle's body and its suspension components, such as the coil springs or struts. By adding these components, the vehicle's body is raised, effectively increasing the distance between the chassis and the ground.
The primary function of a leveling kit is to address the factory rake, where the rear of the vehicle is higher than the front. By raising the front end, the vehicle achieves a more level stance, which can also enhance its aesthetic appeal. This leveling effect not only improves the vehicle's appearance but also allows for the installation of larger tires, which further contributes to increased ground clearance.
In addition to spacers, some leveling kits may include torsion bar keys or coil spring adjusters, depending on the vehicle's suspension design. Torsion bar keys adjust the tension on the torsion bars, raising the front end, while coil spring adjusters modify the spring's preload to achieve the desired height.
By increasing ground clearance, leveling kits improve a vehicle's off-road capability, allowing it to navigate rough terrain more effectively. However, it's important to note that while leveling kits can enhance ground clearance, they may also affect the vehicle's handling and ride quality. The altered suspension geometry can lead to changes in steering dynamics and increased wear on suspension components if not properly installed or if the vehicle is not aligned after installation.
Overall, suspension leveling kits provide a cost-effective and straightforward method to increase ground clearance, improve off-road performance, and achieve a more balanced vehicle stance.
