Your GMC shocks are an important part of your suspension system, and like all suspension system parts, should always be replaced as soon as possible after it is determined that they are no longer functioning within an appropriate range of performance. That is because each of your suspension parts, including your GMC shocks, contributes to the handling and control of your vehicle, including your braking distance. Your GMC shocks are attached to the frame at the top, with the bottom mounting point being on the axle. Over time, road vibration can loosen the mounting bolts of your GMC shocks, leaving either the top or the bottom loose or even dangling. Sometimes corrosion attacks your GMC shocks and other times it is simply the passage of time and wearing out of the inner parts that makes it necessary to replace them. Our online catalog offers a full selection of GMC shocks, and that selection is made up of the standard, stock-style replacements, some higher performing versions, that are designed for vehicles that see regular hard use, such as those that are used off-road, and also we carry custom style shocks, which are meant for use in vehicles that have had height modifications and other changes that directly affect the types of shocks that are needed to provide safe performance. If you compare the prices of our GMC shocks to those that your local dealerships and parts retailers are asking for theirs, you'll probably be pleasantly surprised, as our prices are set to compete and the quality of our parts is sure to satisfy even the most demanding of customers. You can order your GMC shocks online or with a quick toll-free telephone call to our professional customer service staff.
