A suspension lift kit is an aftermarket modification designed to raise a vehicle's suspension system. This kit typically includes components like springs, shock absorbers, and spacers, which work together to increase the ground clearance. By elevating the vehicle, it can improve off-road capability and provide a more aggressive appearance. Installing a suspension lift kit can also enhance the vehicle's ability to navigate rough terrain and obstacles. However, it may affect the vehicle's handling and ride quality, so proper installation and alignment are essential for safety and performance.
