NOx Sensors: A Breakdown to Help You Avoid Breakdowns

An image to illustrate issues with a truck's NOx sensors

What is a NOx Sensor? NOx sensors are exactly what they sound like—sensors that detect NOx (harmful nitrogen oxide particles) in your truck’s exhaust stream. They’re a small but important part of a diesel aftertreatment system. What does a NOx sensor do in a commercial truck? There are two NOx sensors in an HD truck’s […]

Logging Trucks and Idling Issues

The logging industry is a profitable area, but recent years have seen profit margins shrinking and companies struggling with driver retention. One surprising way for companies to recoup profits is through idle reduction. The average long-haul truck loses $10,000-$12,000 USD in fuel every year while idling. These rates are often higher in logging trucks, as […]

Why Did Roadwarrior develop LightningVolt™?

As commercial trucking aftertreatment specialists, we like to be at the forefront of developments and technology improvements. When we saw the potential of idle reduction to preserve the aftertreatment system, we realized two things. Firstly, improved electric APU performance means reduced idle times and less pressure on the engine and aftertreatment system. Secondly, the best […]

APU Batteries Reduce Regens Through Idle Reduction

For most commercial truck drivers, regens range from a minor inconvenience to a significant issue. But did you know cutting down on idling dramatically reduces the regularity of regens, extends the life of your DPF and DOC, and reduces fuel spending? Installing an electric APU with efficient lithium batteries is one of the easiest ways […]

The Upstream Issues Behind Your Aftertreatment Problems

  Heavy-duty aftertreatment systems work with your diesel engine to reduce emissions and increase efficiency. The two systems are interlinked, allowing them to work much more effectively together. However, this also means that if there are issues with one system, they can affect the other. Untreated upstream issues can damage your aftertreatment devices, which in […]

Next Day Is Nice, Same Day is Better!​

A faulty emissions control system can cost you thousands in wasted man-hours as your heavy equipment sits in the shop awaiting a new part. Whether it’s a truck behind on orders, a bus that can’t take passengers, or heavy machinery delaying construction deadlines, Roadwarrior can get you moving again!

Roadwarrior has twelve warehouses across the U.S.A. and Canada, which can deliver the most popular aftertreatment parts in 1-2 days. With over 1,000 DPFs, DOCs and SCRs on offer, Roadwarrior offers the largest aftertreatment catalogue.

*LightningVolt lithium batteries ship directly from Roadwarrior in Ontario, to ALL 50 states, including Alaska and Hawaii within 2-4 days.

Roadwarrior Has You Covered!

All Roadwarrior emissions parts carry a full value 12 month warranty.

LightningVolt lithium batteries carry a full value 30 month warranty.

To make the process hassle-free, our parts have a metal nameplate with the serial number, so even after 500,000 miles of service, it’s still easy to identify. This avoids the common problem of serial numbers printed on stickers that burn off after the first start-up, making them impossible to return. Our failsafe system allows us to work in your interests, honouring claims for on-road and off-road replacements, and giving you peace of mind.

And since Roadwarrior parts are designed to meet or exceed OEM specifications, you can rest easy knowing our direct fit parts will take the problems out of your aftertreatment without interfering with your OEM warranty.

Better Coating, Better Performance.

Roadwarrior is the only manufacturer to use Metalcor® catalyst technology across its entire range of Diesel Oxidation Catalysts (DOCs) and Selective Catalytic Reduction catalysts (SCRs). Metalcor® catalysts feature high activity catalyst coatings fused to thinner, stronger, catalyst substrates to guarantee maximum performance under the harshest conditions.

Metalcor® catalyst coatings are designed and produced in our own labs. We then inspect each unit to ensure you get more fuel efficiency, lower consumption of DEF, and long term performance from your heavy duty engine!
