Duramax Demon
After driving a 525hp Cat-powered concrete truck all day long, Cory Eilek of Cottage Grove, Minnesota, likes to jump in his '05 GMC Sierra Duramax diesel and tool around. Cory has added a K&N Stage 2 cold-air intake to pack the air into his combustion chambers and a 4-inch after-cat MagnaFlow exhaust system with 5-inch tip to get the pulses out.

Bolt-On Bonanza
Derek Graham of Carlinville, Illinois, has hooked up his '04 Chevy Silverado 2500 HD LB7 Duramax truck with a whole slew of aftermarket parts. The four-door, shortbed truck has a 6-inch Trailmaster suspension lift and that allows for plenty of room for the 325/60R20 Terra Grappler tires and 20x10-inch Eagle alloy 114 wheels. Since performance is important to Derek, he installed an Edge Juice with Attitude along with a Mac intake and 4-inch MagnaFlow exhaust. Entertainment is taken care of with an in-dash DVD player and two 8-inch Kicker square subs mounted behind the seat.

Do The Locomotion
If you're sitting at a stoplight and, suddenly, a humongous Dodge Ram 3500 truck pulls up behind you and lets a locomotive horn fly, you might be in Taylor Mill, Kentucky. Since Trey (no last name because his fiancée Julie Bick sent in the photo and neglected to include it) likes to make a big, bold statement, he included the horn for more attention, but he might not have needed it when you look at the truck. The 1-ton dualie has Alcoa wheels, Kelderman Air Ride suspension, Westin nerf bars, Bushwacker fender flares, and a 24-valve Cummins diesel H.O. The 5-inch tractor-trailer style exhaust is custom built.

Who Needs Gas?
Brian Barcroft sent us a picture of his '03 Dodge Ram 2500 4x4 over the Internet, so we have no idea where he lives. Looks cold though. The truck's got the 305/555 H.O. Cummins, a six-speed manual trans, and 4.10 gears in the 9-inch front and 11-inch rear AAM axles. Modifications include a Bully Dog RFI intake, Summit Racing Equipment four-inch stainless steel exhaust, Edge Juice with Attitude, Jacob's exhaust brake, a South Bend Con OFE clutch, and a set of Pro Comp M/Ts. "I traded in my gas hog Hemi for this truck and have never looked back," Brian said. "With all that power on tap and averaging 22 mpg, why would I?" Good question.

Ford Maniac
Some guys are turned off by modern gizmos. Count Rob Fox of Denver, Colorado, among them. He's so proud of his '92 Ford F-350 not just because it's a cool truck but also because the pre-Power Stroke engine is so simple. "There is something truly special about an early 444 diesel engine putting ponies to the ground, [and it] only requires a single 12-volt connection to run," Fox gushes. The 7.3L IDI Ford/Navistar engine was boosted with a Banks Sidewinder turbo, a homegrown water methanol injection system, a boost controller, and a bar and plate intercooler. Rob even learned how to metal cast in order to make an intake hat for his intercooler setup.
