Shock absorbers are what stop your truck from bouncing after a bump. A lot of people think it is just about comfort. The reality is that worn-out shocks directly affect your handling, your braking and your tire wear.<\/p>\n

In summer, with long highway distances, worn shocks turn every trip into a chore and wear out the rest of your suspension early. At Ressorts Laval, we see the difference every day between a truck with healthy shocks and one that dances down the road.<\/p>\n

What a shock absorber really does<\/h2>\n

The spring (leaf or air) absorbs the impact. The shock controls the rebound. Without a shock, your truck would bounce endlessly after every bump. A worn shock lets the wheel bounce, which means the tire loses contact with the road at times. Less contact means less traction and less braking.<\/p>\n

Inside, a shock is a cylinder filled with oil. As the wheel moves up and down, a piston pushes the oil through small calibrated orifices. That resistance turns the energy of the movement into heat, and that is what calms the spring’s rebound. As it wears, the seals let the oil leak out and the orifices no longer control anything: the shock becomes nothing more than a rod sliding in an empty tube.<\/p>\n
