Upgrading coilover springs and leaf springs are common modifications for overland vehicles, providing several benefits for off-road performance and comfort. The primary benefit of upgrading springs is improved load-carrying capacity, allowing the vehicle to handle heavy loads and equipment without compromising performance or safety. Upgraded springs can also improve the vehicle's suspension travel, providing better articulation and traction on uneven terrain. Additionally, upgrading springs can increase the vehicle's ground clearance, allowing it to navigate over more significant obstacles without getting stuck. Upgraded springs can also improve the vehicle's stability, reducing body roll and improving cornering ability. Finally, upgrading springs can also enhance the overall comfort and ride quality of the vehicle, reducing jolts and vibrations over rough terrain.
