It’s official. GM is bringing the 3.0L inline-six Duramax to the AT4X trim for the 2023 model year. Thanks to its advanced off-road capability, premium technology, and an exclusive, luxuriously appointed interior, the AT4X trim level has long offered drivers the ability to venture further off-road with confidence and in comfort. By adding the 3.0L Duramax to the AT4X package, GM expects sales for its diesel option to rise above the 20-percent take-rate it currently enjoys. The updated 3.0L Duramax now produces 305 hp (a 10-percent increase compared to model year 2022) and 495 lb-ft of torque (a 7.6-percent increase from MY22).…

The Shell Rotella Truck Of The Month winner is Marty Tallon. Marty shares with us his long journey of inspiration (and hard work) that created this one of a kind work truck. More than 18 years ago, when I started doing landscaping on my own, I decided I wanted to have a cool, different kind of truck to use for work. What I ended up with was a 1955 Chevy second series 3600 pickup but I actually needed a dump truck. I found a 1973 C/30 Dually dump truck. This truck was in OK condition. It did what it had to for a few years. Eventually, the floorboards had holes big enough to take a bath every time I went through a puddle. So once again, I needed another dump…

Right out of the box, the 6.7L Cummins is a potent performer. But while its variable geometry Holset HE351VE provides instant throttle response, promotes huge off-idle torque, and offers a factory exhaust brake function, its track-record for long-term reliability isn’t exactly commendable. Oftentimes the VGT actuator stops functioning, but occasionally mechanical turbo failure transpires. When either of these problems occur, the owner is faced with a decision to either stick with the problematic VGT or start over with a proven, fixed geometry replacement. Thanks to the displacement increase the 6.7L enjoys over its 5.9L predecessor, a Borg Warner S400-based turbo can be run with no tangible sacrifice in drivability—even with a completely stock fuel system. With the factory Holset VGT beginning to check out on our ’12 Ram 2500 test…

CP4 CLASS-ACTION LAWSUIT MOVES FORWARD Just in case you were wondering where all of the “class-action” lawsuit talk went…a federal judge recently certified seven classes of consumers in a suit against General Motors. The lawsuit, brought forth by Hagens Berman and Hilliard Martinize Gonzalez LLP, accuses the automaker of knowingly selling diesel trucks (i.e. L5P-powered HD’s) fitted with defective Bosch CP4 high-pressure fuel pumps. The class-action lawsuit was originally filed on December 2, 2019, but now the ball is being moved forward once more. According to Hagens Berman and Hilliard Martinize Gonzalez LLP, GM should be held accountable for equipping its expensive trucks with a known-defective fuel pump.…

After a 4-year hiatus, the National Hot Rod Diesel Association is back in business and running at full steam ahead. A record crowd turned out at the organization’s Desert Diesel Nationals event in Chandler, Arizona, the first stop of five on the NHRDA’s 2023 calendar. Diesel drag racing and truck pulling, a big-rig show ‘n shine with Class 8 trucks as far as the eye could see, jet cars, and a massive manufacturer’s midway brought people from all walks of life through the gate at Wild Horse Pass Motorsports Park. And in case you hadn’t heard, the NHRDA season finale will take place in Ennis, Texas from September 15-17 in the form of an East vs. West showdown. HTTPS://NHRDA.COM/…

The scene takes place in Historic, Jacksonville, Florida, located on the Atlantic Coast of northeastern Florida. The most populous city proper in the state of Florida, and the second largest city by area in the United States. The South has and will always be known for its large number of trucks. Daniel Hollis, was born in raised in the Mandarin suburb of southeast Jacksonville. He grew up immersed in the lifted truck culture, mud bogging, vehicle customization, and it’s still in his blood today. While Florida is rich in culture and diversity the truck scene is second to none and growing! GROWING UP “Growing up, we always had to work on our own vehicles, because we couldn’t afford to send anything to a shop. I learned all my hands-on skills…

WP Developments has been working side by side with Outlaw Diesel on a prototype 4R100 trans-brake. It’s something that fans of the Ford four-speed have been hoping and waiting for years, and once it’s been fully tested and validated look for Outlaw Diesel to campaign one on the ODSS circuit. WP Developments posted a video to social media showing the progress of the unit and, while the truck being tested does creep forward a bit, it has nothing to do with the trans-brake. A bad battery was supplying low voltage, which was keeping the solenoid from holding 100-percent. Ford faithful, stay tuned for this breakthrough technology!…

Jeffrey McHaddad and his dad Jeff McHaddad have been big fans and builders of 1955-1959 Chevy trucks. Jeffrey is the builder and Jeff is the creative. They had finished up what they thought would be their last build together when Jeffrey got a call from a friend offering up a one owner, manual, diesel, 1997 Dodge for only $3,000. It was a deal that couldn’t be passed up, and kicked off what would become the insane race truck you see here. CHEAP TRUCK TO RACE TRUCK You might be asking how a cheap Dodge Cummins truck purchase turned into this crazy custom 1958 Chevy Apache race truck. Well, here’s how it came together, in only four months. Jeffrey immediately called his dad and said; “we already have a cab, and…

Ten years into our 600hp stock bottom end experiment, the 225,000-mile 7.3L Power Stroke in our ’97 F-350 keeps on ticking. To be sure, its horsepower recipe is extensive—and includes 350/200 hybrid injectors, an S400 turbo, and a billet internal transmission—but the factory rotating assembly is 100-percent as it was when it first left the assembly line back in the late ‘90s. The heads are untouched for the most part, too, their only upgrades being ARP head studs and stiffer valve springs. Over the course of the last decade the truck has been subjected to dozens of dyno pulls and countless more passes at the drag strip—and it’s all been carefully documented. But while the immediate aftermath of the build meant the truck was often used for play, it continued…
