Shock absorber
The shock absorber controls the rebound and compression of the suspension. It reduces vibration, stabilizes the chassis, and ensures smooth, safe handling under all driving conditions.
A shock absorber is a hydraulic device designed to slow down and control the movement of the vehicle's suspension. It prevents excessive bounce after hitting a bump, helping the tires maintain consistent road contact and the chassis stay steady.
The system works using a piston moving through fluid in a sealed cylinder. Resistance is created as oil flows through internal valves, dampening the suspension's motion. On trucks, shock absorbers are used in both air and mechanical suspension systems, across front and rear axles.
Worn shock absorbers can result in unstable handling, increased braking distance, uneven tire wear, and more stress on other suspension parts. Warning signs include poor ride control, bouncing after bumps, or visible oil leakage.
Key features and uses:
-
Dampens vertical movement caused by road impacts
-
Enhances grip, ride stability, and braking safety
-
Hydraulic resistance system with piston and oil
-
Vital for protecting cargo and minimizing chassis fatigue
-
Available in various sizes, damping strengths, and mounting styles
