      I'm a mechanic and driver for our trucking company, and we've had persistent electrical issues in our Kenworth trucks. Found my old engine wiring harness all chaffed, hence looked up online with the OEM PN 4312327 and came across Roadwarrior aftermarket harness, these guys are the best with excellent customer service and fast shipping. Also the harness works flawlessly.

      Had to order this online because our Peterbilt trucks with Cummins engines were experiencing severe corrosion on the old wiring harnesses, leading to frequent no-start problems and intermittent CEL. It's been great so far, the build quality is amazing.

      As someone who drives and repairs Peterbilt trucks, I've faced numerous electrical problems due to corroded wiring harnesses, leading to fault codes and dead batteries. Ordered this part off of the Roadwarrior website and the trucks are running smoothly without any electrical issues, even during the winter months.

    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.

    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.
