I’m new to the forum but have already spent a little bit of time reading earlier articles and posts (many of them very informative). My friend and I were having a discussion on gear ratios and bigger (35”) tires, specifically for a 2015 6.7l Cummins Ram 3500 (single rear wheel) with the Aisin transmission (stock gearing of 3.42). Over the course of the discussion we had several unanswered questions about re-gearing for that truck and for bigger tires in general: Why is a numerically larger gear ratio (like 4.10) referred to as “lower” gearing while a numerically smaller ratio (like 3.4

What do you think about EGR & DEF deleting on these trucks? When pulling up steep grades this truck temp goes to the top end of normal range some say with deleted engine they will run cooler.

I have a 2013 Ram 4500 6.7L. I only use this truck to pull a horse trailer at 17k pounds max weight. The truck is all stock cab and chassis model with G56 six speed 410 gears. At 65 mph rpm is at approximately 2100 rpm. Is there a way to lower the rpm in 6th gear?

In my view, diesel engines and fuel efficiency follow a simple formula: Run the engine as close to its torque peak, and you'll realize the best fuel efficiency. We have a 2005 Dodge Ram 3500 Cummins 5.9L, stone stock engine, no "chip" or exhaust modifications, the truck is just as it came from the factory (purchased new in fall of 2004). We have a friend with a 2004 model, similar, and we've compared fuel mileage for years now. I've gotten as much as 25 mpg on an unloaded trip from east of Reno, Nevada to Portland, Oregon. I've pulled a loaded car hauling trailer (Jee

I just completed a test cycle with Royal Purple's Max-Tane booster for diesel engines. The magazine's Dodge Ram 3500 4x4 Quad Cab has nearly 140K miles on its odometer now, and the common rail injector system has never required service. The turbocharger has also been trouble-free. With regular preventive maintenance, fuel filter changes and periodic use of gDiesel fuel when available, there has never been the need for injection system service. We have run octane boosters when taking long trips or hauling. This year's run to Moab for the Jeep Safari plus two subsequent trips to Southern

The main concerns when starting a diesel engine in cold temperatures are oil viscosity and the stress on crankshaft bearings. In the lifespan of a properly maintained engine, over 95% of the engine's bearing wear will be attributed to cranking and start-up. This applies to both diesel and gasoline engines. Any reduction in start-up stresses and loads will extend engine life and performance. Your oil choice is a good place to begin. In recent years, there have been several breakthroughs in oil development. Since viscosity choices must match the climate, the latest crop of "winter" oils

In the late 1980s, Dodge Truck sales made a dramatic comeback when Chrysler partnered with Cummins, offering a 5.9L inline six-cylinder, 12-valve Cummins engine option. I test drove one of the earliest models with a three-speed A727 Torqueflite transmission. What a difference that powertrain made in contrast to gasoline engines of the era! Since that time, the 12- and 24-valve Cummins ISB and 6.7L options have made Dodge and Ram trucks a major contender at hauling and performance. The 4WD Mechanix Magazine fleet vehicles include a 2005 Ram 3500 4WD with 5.9L Cummins 24-valve engine, featured i
