Roadwarrior Has You Covered

Roadwarrior is proud to offer the largest aftertreatment catalogue.

Roadwarrior believes in making life easier for customers and mechanics alike, while creating parts you can trust. All our aftermarket parts are designed as direct fit replacements for the OEM parts, with equal or greater quality and efficiency. This ensures that installation is quick and easy, getting you back on the road and keeping your heavy equipment running longer.

Roadwarrior specializes in the construction of aftermarket Diesel Particulate Filters (DPF), Diesel Oxidation Catalysts (DOC) and Selective Catalytic Reduction (SCR). Each part is expertly designed with all the necessary ports and sensor attachments, allowing your new part to operate in the same way as the original OEM part. The new aftermarket parts are tested against OEM parts to ensure they match or exceed the standard of the part they’re replacing. In the case of DPFs, this includes ensuring that backpressure, temperature, and regeneration performance are of the highest standard.

WE ALL KNOW A HAPPY DRIVER IS A PRODUCTIVE DRIVER . THE EXPERIENCE THAT WE HAVE HAD WITH ROADWARRIOR HAS BEEN EXCELLENT AND WE WILL CONTINUE TO BUILD A WORKING RELATIONSHIP WITH THEM .

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.
