Restore Aftertreatment Efficiency

A high performance aftertreatment system enables your engine to be tuned for maximum efficiency at all times. The Diesel Oxidation Catalyst (DOC), Diesel Particulate Filters (DPF), and Selective Catalytic Reduction catalyst (SCR), along with sensors and dosers, treat the emissions from the engine.

Without these devices your engine would need to run much higher EGR rates—harming engine health—and would produce less power as well. When your aftertreatment components wear out or become compromised by upstream malfunctions, the ECU automatically compensates resulting in increased fuel and DEF consumption over time. Roadwarrior offers direct fit components with high performance coatings to restore your fuel efficiency and reduce regeneration frequency.

How Does Regeneration Affect You?

Roadwarrior’s Metalcor® catalyst technology improves your engine’s efficiency by maximizing passive regeneration during more of your drive cycle.  With maximum passive regeneration your engine will getter better mileage due to lower backpressure at high load (when it matters) and reduced consumption of both fuel for active regeneration and Diesel Exhaust Fluid (DEF) used by the SCR system.

How to maximize passive regeneration?

Roadwarrior can help you achieve maximum passive regeneration by restoring or even improving upon the original factory performance.  We do this in three ways:  

1. The activity level of the catalyst coating on the DPF is critical to maximize passive regeneration. With a coating that is degraded due to many cleanings, or even absent when new, the ECU will compensate by using more fuel to perform more frequent active regenerations.

2. A severely degraded DOC will consume extra fuel as it is slowly ramps up to temperature during an active regeneration event. But long before this happens the DOC has failed at its main job which is to enhance passive regeneration.

3. Engines produce more pollution at higher power settings and at higher efficiency. With a properly functioning SCR catalyst the engine is allowed to run as it should without the ECU intervening to reduce power or harm fuel efficiency.

I wanted to let you and your team know that the service manager at the location where you shipped these Detroit One Boxes, was very impressed with the quality of the units. He mentioned that they appeared to be of a higher quality than the units from Detroit that we’ve gotten from the dealer in the past.

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!


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.

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.
