Specializing in interior and exterior truck parts and accessories, CSI makes its products available through stores across the western United States and Canada. It sells light bars, performance, and towing parts and accessories, being notable for offering these at affordable prices. Products include water pumps, cold air intakes, oil pans, timing and differential covers, nerf bars, fuel filler doors, and water pump and alternator brackets. The company's extended range covers winches and other recovery equipment for off-road vehicles, and distributors, alternators, and air cleaners for performance vehicles. There are various items offered for trucks and SUVs.

All of the company's products are covered by a one-year warrantee. During that time, replacement and repair costs are covered should the product be found defective. For LED light bars and off-road lights, the warrantee period is two years. Also, the company makes it convenient to find stores selling its products with a simple online tool while catalogs and instructions can be downloaded at no cost from the CSI website. All parts and accessories are made to high quality standards and even off-road enthusiasts can find affordable products to maximize the power of their muscle cars. Truck and SUV owners have the same perks to look for as well.
