CHROME PIPES AND STACKS
When you look at a truck, what do you see? Some see a piece of equipment for hauling product from point A to point B. Others see their dreams achieved. They see the sweat and tears that create the back-bone of a country. At Grand Rock, that is how we see it!
Your truck is a sense of purpose and a symbol of a great country moving forward. To us, they are art! And like true art, it just doesn’t cut it to own a lower quality duplicate. That is why, for more than three generations, those that see their trucks as more than pieces of equipment have turned to Grand Rock for their chrome exhaust stacks!
Grand Rock Chrome Stacks are the premier truck stacks! They are second –to-none and are renowned for their quality, smoothness, and shine! We take great care in making sure that our products are the most premium quality, with rigorous quality standards and manufacturing processes. This is a difference you can actually see and feel!
When you buy Grand Rock Chrome Stacks you get the genuine article, made in America by a business that cares as much about your truck as you do. Those who love their trucks buy Grand Rock Chrome!
We always love to see what you have done with your work of art, so please share your pictures of your chrome stacks with us by sending them to firstname.lastname@example.org.
Due to the higher heat output of Emissions Components, Grand Rock cannot warrant the Chrome Plating for any item installed on any truck made after 2007. As a solution, ceramic heat barrier coatings can be applied at an additional cost, alleviating the concern. Thank you, Grand Rock appreciates your business and understanding of any inconvenience this may cause.
