A system designed to increase the range of vertical wheel movement in a vehicle. This modification often involves replacing or modifying existing suspension components such as springs, shocks, control arms, and potentially axles to allow for greater articulation and absorption of impacts over rough terrain. For example, an off-road vehicle might be equipped with this system to navigate challenging trails featuring rocks, ruts, and uneven surfaces.
The enhanced articulation afforded by this type of system allows the vehicle to maintain better contact with the ground, improving traction and control. Historically, modifications to vehicles for off-road use have been undertaken to overcome limitations encountered in demanding environments. This resulted in a progression from simple adaptations to sophisticated, engineered systems designed to provide optimal performance and durability.
