The New Ram 1500 Features 'Plastic' Control Arms, And That's Acceptable. Here's the Reason Why.

      Occasionally, I receive a viral truck video accompanied by the question, “Is this real?” Sometimes the answer is yes, but more often it’s a “Well, kinda.” This week, I came across an Instagram Reel with four million views criticizing Ram's use of “plastic” upper control arms. While it has certainly generated buzz, the situation is being exaggerated. Here’s why.

      The video features a few mechanics from All Win Automotive harshly criticizing the design. One comments, “Shameful,” while another adds, “They made their crumple zone the control arms.” It’s understandable why some might think that. It is uncommon to find plastic in an area typically occupied by metal. They joke that it looks like a recycled milk crate, and honestly, they have a point.

      However, there's more to consider. I reached out to Ram for clarification, and while I don’t usually take PR representatives at face value, the spokesperson's explanation checks out:

      “The upper control arm is the same component introduced with the 2019 Ram 1500 (DT) and has consistently performed reliably for seven years (since its launch in 2018). The arms are a composite material integrated with a steel framework. We also apply an e-coating to the component to ward off corrosion.”

      So yes, it features a composite exterior, but inside it remains steel.

      The spokesperson further addressed the criticism that Ram resorted to using cheaper materials.

      “The final product is pricier to manufacture but significantly reduces weight compared to steel or aluminum,” they explained. “This design is part of a lightweight strategy, replacing metal with composites, which provide high-tensile strength with minimal weight. It's also essential to note that the load on upper control arms is minimal compared to the heavier load on lower arms, which created this opportunity.”

      I’ve talked to suspension engineers from various original equipment manufacturers (OEMs), and the general agreement is that upper control arms do not need to match the strength of lower ones. Prioritizing lightweight construction is often more important than high strength, even on heavy trucks. A case in point is the Ford Bronco Raptor, a rugged vehicle on 37-inch tires that features steel lower control arms but aluminum uppers since they aren't as crucial for weight support. While aluminum differs from composite, I have no reason to doubt that the inner steel structure of the Ram is sturdy.

      “Feel free to test it with a magnet,” the Ram spokesperson concluded.

      There are indeed glaring instances of cost-cutting in modern vehicles. I recall the subpar imitation wood used in the Tesla Model Y a few years back. However, it’s important to consider nuance, as not everything online is as it appears.
