Shock rebound, in the context of vehicle suspension, is the rate at which a shock absorber returns to its fully extended position after being compressed by a bump or other impact. It controls how quickly the suspension springs back. It's what allows your shocks to return to extension fast enough to absorb the next bump.
Here's a breakdown:
-
The Basics: When a wheel encounters a bump, the shock absorber compresses. Rebound damping controls how quickly the shock extends back to its original length after this compression.
-
Why It's Important: Proper rebound damping is crucial for maintaining tire contact with the road, controlling body roll, and ensuring a comfortable ride.
-
Too Little Rebound (Fast Rebound):
- The suspension springs back too quickly.
- Can lead to a bouncy or unstable feeling.
- Reduced tire contact with the road.
-
Too Much Rebound (Slow Rebound):
- The suspension returns to its extended position too slowly.
- Can cause "packing down," where the shock doesn't fully extend before the next bump.
- This progressively reduces suspension travel and can lead to a harsh ride and loss of control.
-
Adjustment: Many performance shocks have adjustable rebound damping, allowing drivers to fine-tune the suspension for different road conditions and driving styles.
In summary, shock rebound is the speed at which a shock absorber extends after compression, a crucial factor in suspension performance and ride quality.
