What to Look for in an Aftermarket NOx Sensor?

To accurately measure NOx levels in your exhaust, NOx sensors have to be extremely sensitive. Unfortunately, this means they’re also quite delicate. The average NOx sensor should last for 50,000–60,000 miles, but many of them fail long before this! Most malfunctions are caused by soot build-up, but NOx sensors can also be contaminated by moisture […]

How Does EGR Affect Combustion in Diesel Trucks?

What is a Diesel Combustion Chamber in an HD Truck? Most 18-wheeler and long-haul truck engines have 6 cylinders. Each cylinder includes an ICE diesel combustion chamber—an enclosed space where a fuel and air mixture burns to power the engine.* The piston compresses the air to make it denser and hotter, then diesel droplets are […]

Electrifying OTR Trucking with HDPR and Roadwarrior

Roadwarrior Sales Director Dave Jerman returned to the Heavy-Duty Parts Report (HDPR) podcast for episode 230! He and host Jamie Irvine discussed the electrification of the trucking industry and the role our technology could play. They also explored what the transition to electric trucks could look like, and which truck parts are likely to be […]

Electric APUs and Their Batteries: The Lithium Lowdown

A good sleeper cab aims to fit the key components of a kitchen, bedroom and living room into a space 1/10th the size of a studio apartment. Over time, truck manufacturers have come up with a number of ingenious ways to increase driver comfort by maximizing storage space and interior design. Beyond layout differences, there […]

Lithium Batteries Help Competitive Fishermen Score the Biggest Catch

In a lake fishing contest, there’s a lot of competition for the best spots! Any kind of advantage can make the difference between catching the biggest haul and going home empty-handed. One way to give yourself an edge is by switching to deep-discharge lithium batteries to power your trolling motor and other electronic components. There […]

What is an EGR Cooler and Why Do We Need Them?

EGR (exhaust gas recirculation) became part of the emissions control system in heavy-duty trucks as early as 2002. This part recycles exhaust gas through the EGR cooler and back into the engine’s cylinders to burn with the new fuel. The aim of the EGR is to cut your emissions by burning exhaust more thoroughly and […]

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 […]

House Battery Bank vs Starter Battery

 House Battery Bank vs Starter Battery Most personal vehicles only come with one battery, the starter, which starts the engine. Heavy-duty trucks have much larger starter batteries than non-commercial vehicles because it takes much larger engines to pull them. However, modern commercial trucks, fitted with electric APUs (auxiliary power units), often also have a house […]

The Modular One-Box: Breaking Down the Future of Aftertreatment

  In two years as the only aftermarket replacement One-Box manufacturer, the Roadwarrior R&D team has developed our expertise considerably. We’ve expanded Roadwarrior’s design offering to include not one, but four different One-Box models. Recently, we also achieved the challenging technical feat of developing a modular One-Box. The compact, modular One-Box is one system combining […]

Are Construction’s Diesel Engines Becoming Greener Machines?

  From bulldozers, earthmovers and excavators to mobile cranes and pavers, the vast majority of North America’s construction equipment is fuelled by diesel. In the US, construction actually makes up 55% of off-road fuel use, according to the Diesel Technology Forum. A few years ago, this might have been a bad thing for the environment. […]

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!
