OE Pipe Coverage
Grand Rock has the most extensive aftermarket OE-specific replacements for all major brands in the market. Fit, form, and function are all critical components of making the replacement of your old, worn out OE parts simpler. Many aftermarket companies put "slight deviations" in their pipes, causing you to have to buy more parts and spend more time replacing your system. That is why Grand Rock focuses on creating a near identical part to your original - that way, you can quickly swap one part for the next, keeping your trucks on the road.

The benefits do not end there! With the largest selection of parts, we make it easy for you to shop for all of the components you need quickly and without hassle. And, we deliver to all 50 states! In addition, all of our catalog parts are kept in stock at our 50,000 sq. ft. facility. So, when your truck goes down, you can have it up and running in no time.

Why go to the OE and pay OE high prices when you can get a better part for less?
