When it comes to custom ordering a Chevy Silverado, the process can vary depending on what exactly you are looking for. However, on average, it generally takes around 6-8 weeks to complete the entire process from start to finish. This includes everything from placing your order with the dealership to taking delivery of your new truck. Keep in mind that this is just an estimate and there may be some factors that could affect the timeline, such as the availability of certain parts or accessories. Overall, though, if you are planning on customizing your Silverado, be sure to allow yourself enough time to do so.
