Dorman Passenger-Side Windshield Wiper Arm 602-5404

Where it shines

When the passenger-side wiper arm has stopped working as it should, replacing the arm may be a more focused repair than replacing a broader part of the wiper system. The Dorman 602-5404 is designed as a direct replacement for the original arm on specified vehicles.

Its purpose is practical: restore wiper-arm function when the original has failed because of spring wear, snow damage, or metal fatigue.

If you prioritize replacing just the failed arm, this part follows that approach, if you prefer to replace a larger portion of the wiper system at once, this is a narrower repair.

What matters most

This is the passenger-side arm, and the listed fit is limited to select Kenworth models. The product description says it is designed to match the fit and function of the original arm on specified vehicles, but it does not name those vehicles. That makes exact fitment the key buying decision—not just whether your truck is a Kenworth.

The listing advises entering the vehicle’s make, model, and trim level in its fitment tool. Use those details before ordering, especially if your truck has a particular trim or configuration. Without having tried it, the most useful takeaway is that this is presented as a replacement for a failed arm, not as a universal wiper component.

The description calls out durable construction and materials intended to support reliable performance, but it does not identify the material or provide installation details. If you need those specifics to decide, they are not established in the supplied product information.

Best use cases

This arm makes the most sense when the passenger-side original has failed and you want to replace that component rather than take on a wider wiper-system repair. For example, if the passenger-side arm is damaged after snow exposure while the issue is isolated to the arm, a matching replacement is the repair this product is meant to serve. It does not, by itself, establish that a worn wiper blade or another part of the system will be addressed.

The practical limit is that the description covers the arm’s intended role, not the condition of the rest of your wipers. If you are dealing with multiple wiper problems, or need a complete system solution, check what else requires attention before treating an arm replacement as the whole repair. The listing also does not provide care or cleaning instructions, so there is no specific maintenance routine to rely on here.

Should you buy it?

Worth considering if your repair is specifically for the passenger-side arm, your vehicle is among the select Kenworth models it fits, and the original has failed from wear or damage. Dorman presents it as a direct replacement, which suits a targeted repair better than buying a broader set of components you may not need.

It’s not for you if you cannot confirm fit for your exact make, model, and trim, or if you are looking for a complete wiper-system replacement. The supplied details leave the compatible vehicle list and installation specifics unstated, so this is a buy only after the fitment check—not a safe guess based on the brand of truck alone.
