Caterpillar Parts

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.
