Shocks are used on every suspension system out there. As the suspension actuates and goes over bumps, the shocks absorb the impact to keep the suspension from continually bouncing up and down as you’re going down the road. Shock absorbers there to make your trailer ride more efficient and more comfortable.

The primary function of the shock absorber in a commercial trailer is to keep the tires in constant contact with the road. Shock absorbers vary in quality greatly, which do directly affect whether your shocks are helping to provide optimum grip when cornering and braking. That’s why it’s best to order only the best of the best from Hendrickson.
