Performance is an interesting thing to measure, isn’t it? Today, enthusiasts are spoiled, because through big horsepower or torque readings from engine and chassis dynos, we can forecast a truck’s e.t. and mph on the dragstrip, or how far a particular rig can pull a sled. We can do the same thing the old-fashioned way.
Rather than relying on a time slip or dyno sheet, we can rely strictly on the feeling we get when the throttle is hammered and the speedometer needle climbs like the temperature probe in a nuclear reactor. That’s the kind of fun everyone understands, and it’s exactly what Jocko McCants, owner of this ’10 Ram 2500, was looking for when building his beastly blue rig. Jocko’s name may be familiar to regular Diesel Power readers, because we featured his killer Cummins-swapped ’10 Ford F-450 in our May ’17 issue. The man sees trucks as tools, and while that F-450 fills one role, this Ram is designed for another.
Photo 2/130   |   This 6.7L Cummins engine is as clean as a whistle, and it is making some serious power. With a slew of BD Diesel Performance components, including its RT850 Track Master compound-turbocharger kit, this truck has power by the bucketload. Want to talk details? How about the graphics on the valve cover and assorted plumbing?
“This Ram is my baby, and since I already have a rig that can tow whatever I want to wherever I want, my goals for the Ram are different,” Jocko says. “My problem with having a bigger truck like this is there are always people trying to get under it. Guys in little cars have a bad habit of trying to do that, so I wanted something that would be able to walk away from those types of situations. I love the power this one has. I see guys stand on the throttle, make a bunch of smoke, and then go nowhere. I’m halfway down the road before they know what happened to them.”
Photo 3/130   |   There is just something about a truck build that has been thoroughly executed. Every inch of this Ram has been touched in some way. From the lights and the wrap to the suspension, engine, and interior upgrades, this rig is ready for whatever comes its way.
As the owner of a repair shop specializing in German cars, Jocko understands the value of a few important things. He knows quality parts, workmanship, and customer service are key elements for not only making a business work, but also for it to be successful. “I got with the guys at Advanced Diesel Works on the project because I have worked with them before, and they are great,” Jocko explains. “They look at projects like this the same way I do. I go to SEMA and a lot of events and see these trucks that look great from a distance and then you get up close and see they are not truly finished. Every vehicle I have has to be finished, and that’s why this Ram is built the way it is.”
Photo 4/130   |   This blue beast heads into the wilds of Montana on a regular basis, where it can be as dark as the backside of the moon. Jocko’s Ram 2500 has more illumination than he will probably ever need. Those red and blue lights? Let’s just say they come in handy now and again.
So, how is it built? Well, instead of simply lifting the rig, putting bigger wheels and tires on, and calling it good, both axles are upgraded. Each of them has 4.56 gears, and the front is upgraded with RCV Off-Road Performance Products high-performance axleshafts and a Dynatrac Free-Spin kit that facilitates manually locking and unlocking the hubs. “Gearing is an area I think a lot of people overlook,” Jocko says. “I have driven lifted trucks with big tires on them, and they don’t go anywhere because the stock gearing has been left alone. Because I want this truck to perform at a high level, even with the larger wheels and tires, the 4.56 gears are the right choice.”
Photo 5/130   |   Jocko McCants is a real fanatic for doing things the right way and totally completing a job. One example of this is actually behind the differential cover on his ’10 Ram 2500, where 4.56 gears were added to compensate for the truck’s 37-inch-tall tires.
Photo 6/130   |   Knowing Jocko like we do, we expect nothing less than perfection when it comes to his pickup’s suspension. To achieve a true 8-inch lift, Advanced Diesel Performance integrated BDS Suspension front coils springs with Top Gun Customz control arms for the visual and handling results Jocko demands.
Giving the Ram its brutish presence is a truly interesting suspension system that again comes from the owner’s wants and needs, along with the skilled background of the crew turning wrenches. Using BDS Suspension’s front coil springs as the foundation for a true 8-inch lift, Top Gun Customz control arms anchor the axle to the chassis, and Fabtech Motorsports Dirt Logic shocks bring control to the whole system. In the rear, Carli Suspension’s Add-a-Pack leaf springs ride on custom-fabricated 4-inch blocks. There are also Firestone Air Command F3 airbags back there, and a pair of the same Fabtech shocks that perform up front. Custom traction bars help plant the tires. “I am obviously pretty picky about things, and that goes double for the suspension,” Jocko says with a laugh. “I drive the truck a lot and for long distances. It has to ride well, handle well, and do all of it without stuff rubbing or binding up. We used a mix of different parts, but the end result is exactly what I want the truck to sit and ride like.”
While the suspension may contain parts and pieces from multiple different manufacturers, the thumping heart of this blue bandit is the opposite. The 6.7L Cummins engine is smartly hot-rodded with a plethora of parts from BD Diesel Performance. Internally, the engine is stock, aside from being upgraded with ARP cylinder-head studs. This was done to ensure a good seal with the increased boost and combustion pressures that come along with adding more fuel and air to the party. Using a Fleece Performance Engineering PowerFlow 750 CP3 injection pump and Torque Diesel Motorsports Stage 1 injectors to deliver the fuel, the air comes by way of BD’s RT850 Track Master compound-turbocharger setup that uses BorgWarner AirWerks S300 and S400 ’chargers to pack the boost in. A BD intercooler and air horn get the pressure into the engine, which is where the real fun begins. Snow Performance water-methanol injection keeps the EGT low.
“I love the way the Cummins runs,” Jocko says proudly. “I also love the way the engine looks. The hydro-dipped graphics are great, and they set the truck apart and finish the whole thing off. The horsepower and torque are ridiculous. More than once, I have pulled onto the highway at part throttle only to look down and see the speedometer needle buried!”
If you happen to be in Washington State cruising down the road and this big blue brute of a Ram shows up in your rearview mirror, just go ahead and get on out of the way. Jocko’s got places to go, and he’s coming by you one way or the other!
Photo 7/130   |   This Ram has an awesome presence and one of the reasons is the handbuilt Throttle Down Kustoms bumpers. The big front bumper encloses a top-of-the-line Warn winch and gives the impression that this Ram can run through a mountain without getting a scratch.
Photo 8/130   |   While Jocko’s rig is blue from the factory, it is not this shade. In fact, the rig is wrapped, not custom painted. The evolution of vehicle wrapping over the last several years has really expanded the possibilities when it comes to styling a rig like this. This icy blue looks great.
Photo 9/130   |   No, this is not a brand-new Ram, it’s just owned and cared for by a perfectionist who wants to make sure it remains nicer than new for its entire existence. We know those of you in Rust Belt states may be mystified by this sight, but, wow, the bottom of this rig is clean!
Photo 10/130   |   The combo of the Fabtech Motorsports Dirt Logic 2.25-inch shocks, Carli Suspension Add-a-Pack leaf springs, 4-inch fabricated blocks, custom traction bars, and Firestone Air Command F3 airbags makes the rear suspension functional and capable.
Photo 11/130   |   The 6.7L Cummins in this Ram 2500 is not just dressed nicely, it makes some real steam. Note the cool hydro-dipped plumbing and pieces in the engine compartment. What you cannot see inside the powerplant is an ARP cylinder-head stud upgrade. The big I-6 puts four-digit torque to the ground.
Photo 12/130   |   BD Diesel Performance is an industry leader because the company puts the necessary research and development into its parts to ensure they fit right and work properly for end users. You have to appreciate the packaging of this turbo kit.
Photo 13/130   |   When we photographed the Ram, Jocko had light interior modifications in the form of gauges and some cool hydro-dipped elements. He told us that upgraded seats and some wild headliner modifications are in the cards for the future. This guy can’t leave anything alone!
