Cummins

As one of the most popular heavy equipment manufacturers, aftermarket parts for Cummins diesel engines are well represented in the Roadwarrior catalogue. Roadwarrior’s high-quality Diesel Particulate Filters (DPFs) and Diesel Oxidation Catalysts (DOCs) help you avoid recurring Cummins aftertreatment problems. The brand-new replacement parts measure up to or improve on the original, so you can get the highest performance standards from your diesel engine. This means less time wasted over plugged DPF filters and forced regens, and more time fulfilling orders. Heavy-Duty Emissions parts for Cummins need to be robust and strong, Roadwarrior can help with that. Heavy-Duty Emissions parts for Cummins are in-stock and ready to ship

There are a lot of similarities between Cummins and Paccar engines, and some of their parts may be interchangeable, but their DPFs are not! Some manufacturers will try to substitute a Paccar DPF for your Cummins engine, but they are designed differently for good reason. Your substituted part may start to fail prematurely because it’s not designed to meet OEM specifications. To lighten your load, Roadwarrior developed two separate aftermarket parts for Cummins and Paccar engines because our engineers don’t take shortcuts.

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 parts include a full value 1-year 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.
