2003 Ford F250 Buildup - Banks PowerPack System

After seven years of service, this daily driven 2003 Ford F-250 was due for a change. There was just too much off-road potential to be sacrificed with the stock suspension and average ground clearance. After driving the newer coil-spring front suspension Super Duty we knew it was possible to coax a good ride out of a solid front axle HD truck, but what were our options with our older, leaf spring truck? After a few calls and some suggestions, we decided to go with the recommended set of Deaver 4-inch lift springs and all of the necessary components to give the Super Duty added capability and a better ride at the same time. A set of new Nitto Trail Grappler Mud Terrain tires and USA Forged wheels would allow the Ford to go off the beaten path, and where else would we turn to add a healthy boost of horsepower for an HD truck but Gale Banks Engineering? A complete Banks Power Pack would unleash 56 hp and 67 lb-ft of torque that we didn't know the V-10 was hiding. To handle the suspension install, we took a short drive to 4 Wheel Parts, in Redondo Beach, California, where the 4WD gurus had our Super Duty up in the air in no time. Read along and see how, in just one day, this tried and true Ford F-250 went from a boring daily driver to trail-ready rig thanks to several high-quality, bolt-on parts.

With wrenches and a reciprocating saw at his disposal, Joe Wilson, installer at Banks Engineering, had the old exhaust broken down into manageable sections in just a matter of minutes. The crew cab truck had quite a bit of exhaust to remove, here's the huge muffler and giant catalytic converter ready for the recycling bin.
