Axle Articulation
Axle articulation is how far the suspension lets the wheels move up and down independently to keep them in contact with uneven ground.
What is Axle Articulation?
Good articulation keeps more tyres on the ground off-road. Solid axles and long-travel suspension usually articulate well. Anti-roll bars can limit articulation. Off-roaders use a ramp test to compare how much articulation vehicles have.
How it works
When one wheel rises, the suspension lets others drop so all tyres keep traction.
Why it matters for your car
A lifted wheel can spin freely unless a locking differential or traction control helps. Modifications that increase travel may affect on-road handling.
