ROQ Crusher
Jay “Lightning” Tilles of KROQ fame brought us a bone-stock 2006 Duramax Dually which we transformed into the fire-breathin’ behemoth.
When Jay Tilles (AKA Lightning from a local radio station called KROQ) called and asked if we could help him with his SEMA show truck, he was only expecting a few of our standard Power Products. Little did he know that he was in for the Banks Power modification of his lifetime. Once we got our hands on his truck, we decided like usual to go big or go home. So we went BIG! This beast not only has every product we could possibly throw at it, but there is custom tuning and products on here that may never be available to the public (and some that will).

Cummins Grid Heater Bolt Fix: Banks Monster-Ram
On all 6.7L Cummins, the factory grid-heater bolt is a known risk: if it breaks loose and reaches cylinder #6, engines are replaced—not repaired—an outcome costing north of $30,000. If you do nothing: the stock grid-heater bolt stays in the system—every start is a roll of the dice, and other replacements “fixes” still choke air flow. […]
