Custom Truck Projects & Diesel Conversions
From custom Cummins engine swaps and built transmissions to BDS suspension lifts and frame-off restorations, Diamond Truck Service builds vehicles ready for Alaska's toughest terrain.

2004 Ford F-350 Fummins Frame-Off Build
Built right here in Anchorage, this 2004 Ford F-350 Super Duty underwent a painstaking frame-off nut-and-bolt restoration. We stripped the vehicle down to bare metal, coated the chassis for lifelong Alaska corrosion resistance, and engineered a custom 6.1L 12-valve Cummins swap paired with a built transmission, 2006 coil axle conversion, 8-inch BDS lift with Fox suspension, and a full 2010 Lariat interior swap.

Suspension & BDS Lifts
