What Wheel Travel Means
Wheel travel is the vertical distance a single wheel can move between full compression and full droop. It is the foundation of articulation: the more a wheel can reach down into a hole or up over a rock while its partners stay loaded, the more grip you keep. Long-travel and well-articulated suspensions are what let tires follow the terrain instead of lifting and spinning.
The Role of Motion Ratio
Shocks are almost never mounted directly over the wheel, so the wheel moves more than the shock does. The motion ratio captures that multiplier. A ratio of 1.2 means the wheel travels 1.2 inches for every inch of shock stroke. Getting this right is essential when choosing shock length, because the wheel travel you feel depends on it.
Up-Travel and Droop
Where the suspension sits at rest decides how the total splits between compression and droop. Too little droop and a wheel lifts off as the chassis twists; too little up-travel and it bottoms harshly. A balanced split keeps tires planted and the ride controlled, which matters more off-road than raw travel numbers alone.
Frequently Asked Questions
How do I find my motion ratio?
Measure how far the wheel moves versus how far the shock compresses over the same motion. Coilover and link setups often run near 1.0, while inboard shock mounts and bell cranks push it higher.
Is more travel always better?
More travel helps articulation but needs longer shocks, room to fit, and attention to droop limits and driveline angles. Balance travel with control and packaging.
Why does droop matter so much?
Droop lets a wheel stretch down into dips and stay loaded while the chassis flexes, which is what keeps all four tires gripping on uneven ground.
