Just like in any other vehicle on the road, the suspension system of your semi truck exists to perform two essential functions. It supports the weight of the truck, and absorbs road imperfections and terrain changes. At first blush, this doesn't sound too complicated, although, taking into account the weight of your semi truck, the work your suspension system does is really huge, so each of its components needs to be extremely durable and reliable. That's why, when it comes to suspension system repairs and upgrades, make sure you purchase only first-class products, like semi truck suspension parts we offer.
