Grand Rock has manufactured diesel truck exhaust systems for over 30 years. They custom make 100% of their product in their 53,000 square foot Ohio factory just east of Cleveland. In addition to having OEM Replacement Parts for big rigs like Kenworth, Peterbilt, Mack, Western Star, International, Volvo and Sterling, Grand Rock has created their PowerFlow Division.

The Grand Rock PowerFlow Diesel Pickup stacks bring big rig-style stack kits patterned after traditional tractor-trailer stacks to today’s popular GM Duramax, Ford Powerstroke and Dodge Cummins diesel pickup trucks. They fabricate their 4" and 5” stacks from 16 gauge cold rolled steel, and the 6” and 7” and the brand new 8” stacks are fabricated from 14 gauge cold rolled steel.

After fabrication, most PowerFlow stacks are given a high quality commercial grade durable triple-chrome-plating, although some customers choose to finish the tips themselves and order the stacks without a finish so they can do a custom treatment or coating.
