Manufacturers

Roadwarrior offers the latest aftertreatment technology for trucks, buses, and construction equipment. These efficient aftermarket parts are exact fit replacements for popular heavy equipment manufacturers including Cummins, Caterpillar and Detroit Diesel. With over 1,000 DPFS, DOCs and SCRs, and the option of same-day pickup or next-day delivery for the most popular parts, Roadwarrior is here for you.

 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.

 Caterpillar

Caterpillar equipment is well-designed and reliable, but no heavy equipment lasts forever. Whether it’s a Cat diesel truck, or heavy machinery on your construction site, a failed aftertreatment part creates problems you really don’t need. Buying old reman parts gets you moving again, but often means another breakdown soon afterwards, causing more delays and more costs. Roadwarrior’s new aftermarket DPFs, SCRs and DOCs are designed to offer the ultimate performance standards, letting you get another 500,000 miles out of a well-maintained Caterpillar truck. As the only manufacturer to offer aftertreatment parts for construction, a premium new Diesel Particulate Filter could dramatically increase the work life of your heavy machinery too.

 Detroit Diesel

When the EPA introduced legislation lowering legal emission standards, Detroit Diesel introduced the one-box aftertreatment system. The one-box combines the Diesel Particulate Filter (DPF), Diesel Oxidation catalyst (DOC) and Selective Catalytic Reduction (SCR) into one system. By introducing a catalytic converter, the one-box keeps your diesel engine’s emissions within legal limits and the air you breathe clean. But your aftertreatment system has a shorter working life than your truck, and after 500,000 miles it may be worn out. That’s why Roadwarrior developed the first and only effective aftermarket one-box, to complement our other Detroit Diesel aftertreatment parts. While a pre-cleaned reman replacement often fails soon after purchase, a brand new Roadwarrior part offers you up to 500,000 extra miles on your diesel engine.

 Komatsu

Since the introduction of Tier 4 emissions standards, Komatsu and other major manufacturers have included an emissions control system with a DPF and a DOC in all new construction equipment. A good aftertreatment system complements your diesel engine, increasing fuel efficiency and reducing harmful emissions, but a faulty one can cause troublesome delays. As the only aftermarket manufacturer of construction aftertreatment systems, this is where Roadwarrior becomes the ace up your sleeve. Roadwarrior parts can be ordered from your local distributor and delivered in 1-2 days, getting your Komatsu heavy machinery going and your project back on track.

 Navistar / Maxxforce

The transportation industry relies on good design, and that means every aspect of the heavy equipment involved working seamlessly, including the aftertreatment system. If the DPF on your Navistar bus isn’t effectively reducing emissions, you can’t transport passengers. If the DOC or SCR on your Navistar truck needs replacing, you can’t complete orders. If the recent controversy around the Maxxforce engine has shown anything, it’s the importance of a good emissions control system. Roadwarrior’s catalogue of aftermarket parts are ready to exceed your aftertreatment expectations, keeping all your diesel engines emissions-compliant and running smoothly.

 Volvo/ Mack

Mack’s advanced designs offer a flexibility of body builds and configurations, in trucks and semi-trucks, that’s attractive to both trucking and construction workers. But no matter what you’re hauling, whether you’re on-road or off-road, issues with your Mack exhaust aftertreatment system can create serious delays. Don’t let that be a spoke in your wheel—Roadwarrior has an extensive selection of brand-new Volvo Mack parts to get you back on track. As well as DPFs and DOCs, the aftertreatment catalogue includes advanced Selective Catalytic Reduction (SCR) catalysts and combustion chambers. Whatever your emissions control needs, Roadwarrior has the replacement part to get your heavy equipment going.

 General OEM

Every construction site manager, fleet owner and truck driver, has different considerations and requirements when it comes to choosing heavy equipment. Different manufacturers and models meet different needs and budgets, so even exhaust aftertreatment problems, which affect every older diesel engine, don’t have just one solution. That’s where Roadwarrior comes in, offering the largest aftermarket emissions control catalogue, for the widest range of OEMs. Roadwarrior replacements range from clamps and gaskets, to complex systems like Selective Catalytic Reduction (SCR) and replacement one-box systems. The Roadwarrior catalogue encompasses busses, trucks and construction equipment, with the most popular parts ready to ship to your site in 1-2 days.

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.
