What does "bump travel" refer to in suspension terminology?

Bump travel in suspension terminology specifically refers to the maximum distance that a wheel can move upward when the vehicle encounters a bump or obstacle in the road. This movement is crucial for maintaining tire contact with the surface, providing better control and comfort during driving. When a wheel travels up due to a bump, the suspension system compresses to absorb the impact, and the distance it travels in this upward direction constitutes the bump travel.

Understanding how bump travel functions is important for vehicle performance, as it affects how well a car can handle rough surfaces and maintain traction. Adequate bump travel ensures that the suspension can effectively manage both small irregularities and larger obstacles, which directly impacts ride quality and vehicle stability.
