This build focused on the places a late-model Ram 2500 feels held back: intake restriction, lazy pedal response, exhaust backpressure, differential heat, and the factory grid-heater layout. Up front, the Banks Monster-Ram Intake and Killer Grid Heater Upgrade replaces the stock grid heater with a high-flow billet intake plate, opening the path between the intercooler and manifold while removing a known failure point from the airflow path. Larger 3.5-inch boost tubes and the Banks Ram-Air Intake System improve air density to the turbo and help the engine breathe easier. Out back, the Banks Monster Exhaust System with SideKick tip reduces backpressure so the engine gives up less work on the exhaust stroke. Under the truck, the Ram-Air Rear Differential Cover uses bottom scoops and long internal fins to move heat out of the gear oil more effectively. Tie it together with iDash DataMonster and PedalMonster, and the truck feels quicker, cleaner, and more responsive with useful data to back it up.
Emma brought in her Ram 2500 turbo diesel as a surprise project for Stephen, who had been away in Virginia for months. Her plan was to have the truck upgraded without his knowledge, then pick him up from the airport and reveal the finished build. The truck was first handed over to Banks for powertrain, airflow, exhaust, driveline, and electronics upgrades before moving on to CJC Offroad for suspension, wheels, and tires.
Banks began by improving the engine's intake path. The truck received a Monster-Ram intake elbow, which is intended to improve throttle response and fuel economy by reducing restriction between the intercooler and the intake manifold. That upgrade also eliminates the stock grid heater arrangement, replacing it with a high-flow billet intake plate and thereby preventing the well-known grid heater bolt failure issue.
The boost tubes were also enlarged from the stock 2.5-inch diameter to 3.5 inches. To further improve airflow into the turbocharger, Banks installed a Ram-Air cold-air intake system. The stated goal was to increase air density at the turbo inlet, while the larger air filter was described as staying clean much longer than the stock filter, which would become dirty and clogged sooner under similar conditions.
Under the truck, Banks installed a 5-inch Monster Exhaust system along with the company's patented SideKick negative backpressure tip. The explanation given was that reducing backpressure in the exhaust system lowers the amount of work the crankshaft must do during the exhaust stroke. In practical terms, that means recovering horsepower that would otherwise be lost pushing exhaust gases out of the system.
Banks also replaced the factory stamped-steel differential cover with its patented Ram-Air rear differential cover. According to the build description, this cover cools five times better than stock while using only four quarts of fluid. Its lower scoops channel cool air upward through long, thin fins, improving heat rejection from the differential.
Inside the cab, the truck was fitted with an iDash DataMonster, described as the central nervous system of the Banks package. In addition to displaying familiar parameters such as boost, EGT, transmission temperature, and other standard data, it can also show patented calculated values that typical instruments do not provide. Examples mentioned included manifold air density and boost air density, allowing the driver to evaluate intercooler effectiveness and other aspects of engine performance.
The iDash also serves as the control interface for the PedalMonster throttle controller, which was hidden under the dash. That device is intended to remove the throttle lag commonly felt in the Cummins inline-six application. Rather than changing engine output directly, it sharpens the relationship between pedal input and throttle response, making the truck feel more immediate and reactive.
After Banks completed its portion of the build, the truck went to CJC Offroad for chassis work. The suspension package chosen was the Carly Suspension Pintop 3.25-inch system, similar to the setup used on Banks' own truck. CJC emphasized Carly's engineering approach, comparing it to Banks' focus on research, development, and explaining why its products differ from simpler alternatives.
The front suspension uses fully Carly-tuned King shocks with stainless steel shock shafts, Carly-specific piston design, and Carly's own tuning. Those shocks are paired with soft-ride coil springs intended to deliver a compliant ride both on and off the highway. The point made during the build was that Carly suspension is often associated with off-road performance, but it also rides extremely well on-road and around town.
Additional components were included to preserve factory suspension geometry rather than relying on shortcuts. CJC specifically noted that many companies omit these supporting parts, while Carly includes them to maintain proper alignment and handling characteristics. In the rear, the truck received matching soft-ride coil springs, custom-tuned King 2.5 shocks, sway bar end links, and a track bar drop bracket, all intended to keep the truck's geometry correct while improving ride quality on and off road.
The truck was then fitted with CJC-spec Raceline 17-inch Avenger wheels. CJC pointed out that there are relatively few 17-inch wheel options for Ram 2500 and 3500 trucks that provide the proper offset needed to run a 37x12.50 tire with minimal trimming.
For tires, the build used Toyo RTs in 37x12.50 size. The tire was described as riding very well, providing strong traction, and avoiding excessive noise, making it a practical all-around choice for most users. Combined with the suspension system, the wheel-and-tire package significantly changed both the truck's stance and its capability.
Once the truck returned from CJC, Emma got her first chance to drive the completed build. Because she already knew how the truck felt in stock form, the demonstration focused on the PedalMonster settings through the iDash. She was instructed to use the up arrow to increase the setting into the higher sport range, and the truck immediately showed a much more aggressive response. Even on 37-inch tires, the truck broke traction easily, illustrating how much more immediate the pedal mapping had become.
One feature highlighted during the drive was the reverse safety logic. When Emma shifted into reverse, the iDash displayed "Reverse Mode," indicating that the throttle controller had reverted to a stock-like setting while backing up. The explanation was straightforward: the system avoids aggressive throttle behavior in reverse for safety. Once shifted back into drive, the truck returned to the selected sport setting.
Emma then tried the highest setting, described as track mode. Her reaction centered on how quickly and effortlessly the truck accelerated. She noted that it did not feel sloppy, but instead felt fast, nimble, and responsive with very little pedal effort. She compared the sensation to her Challenger, but said the Ram felt beefier and even faster despite being a 2500-series truck. The sharper response and ease with which the truck accelerated were the most obvious changes from the driver's seat.
Emma then picked Stephen up and revealed the finished truck. Seeing the completed build for the first time, he was visibly surprised and said he was speechless. The reveal included the full visual transformation as well as the Banks and CJC hardware that had been added while he was away.
After taking the keys, Stephen immediately noticed that the truck felt quick on the pedal even before doing anything more aggressive. Once he drove it, he commented on the strong response and how quickly the power arrived with only light pedal input. He also remarked on the ride quality, noting that the truck rode very well despite the larger suspension and tire package.
Both Emma and Stephen focused on the same overall impression: the truck now responded instantly, accelerated effortlessly, and felt far more refined than stock. Stephen specifically praised the engineering behind the package, calling out the response time and the amount of power available from only a small pedal movement. He also appreciated the audible turbo whistle, which added to the sense that the truck had become much more alive without losing drivability.
