Store of Dave's auto repair Utah ad: Built by diesel mechanics, not marketers.

Most performance parts are designed in a boardroom. This one was proven in a diesel shop. The Hamilton Cams Flat Tappet Conversion Kit isn’t just another upgrade. It’s the same valvetrain setup used by mechanics who build Cummins engines every day — designed to improve durability, reduce friction, and support serious towing or performance builds. When the people who repair engines choose the parts they trust… this is what they install. Upgrade your Cummins with a kit that’s tested where it matters most — in the shop.
