If you have been out of the country for a couple years and just dropped back into life on the road towing your big travel trailer, you probably noticed there’s a lot of talk around the RV campground about hot-rodding diesel-powered pickups. You may have also noticed that your tow rig seemed to get a lot slower since the last time you drove it.
Well, it may not have slowed down at all. What you’re seeing is a lot of other diesel trucks have become a lot more powerful.
A sudden diesel performance swell has swept across the country, bringing with it a huge number of new manufacturers and products that can turn the doggiest of diesels into decent performers.
Today;s performance upgrades can be electronic or mechanical, simple or complex. They can range from following a few simple instructions on a hand-held programmer to getting out the hand tools and replacing the turbo or injectors.
Such upgrades can give your diesel pickup or SUV more power, make it more efficient, and make it more enjoyable to drive—with or without trailer in tow.
To give you just a small glimpse of what types of new products are out there, we’ve compiled a selection of hot new diesel performance products. There are numerous companies that offer them, and shops all across the country that specialize in the installation of such upgrades if you are so inclined to pass on doing them yourself.
Whether you choose one upgrade or a combination, the end result is a tow vehicle that does the job of towing a big trailer with a lot more ease. That takes a load off the driver.—TL
HOT AIR FILTERS
Cooler air, more power is a hot-rodding mantra. Advanced Flow Engineering Cold Air Intake Systems do just that. They claim the GM 01-04 LB7 Duramax Diesel kit adds 15 horsepower and 34 Ft/Lb of torque while the Ford 6.0L Power Stroke version adds 14 Ft/Lb of torque, 18 horsepower and faster turbo spool-up.
