When it comes to keeping an excavator fleet running smoothly, replacement parts are a necessary part of the job. But ask around, and you’ll hear mixed opinions about aftermarket options. Some swear by them, while others are convinced they’re just cheap substitutes for OEM parts.
The truth? Not all aftermarket parts are created equal. We-Attach, the leading excavator parts manufacturer, has seen how well-made aftermarket components can match or even outperform OEM standards when chosen wisely. This article takes a closer look at five common myths and clears up the confusion, allowing you to make smarter decisions without second-guessing every bolt or bracket.
Myth #1: “Aftermarket Parts Are Just Cheap Knockoffs”
One of the most common assumptions is that aftermarket parts are of low quality. It’s easy to see why: plenty of bargain-bin suppliers cut corners, and there’s a flood of questionable products on the market. But that doesn’t mean all aftermarket parts are poorly made.
Reputable manufacturers utilize high-grade materials, precise machining, and rigorous quality control to produce components that meet or exceed OEM expectations. Some even improve on original designs by analyzing common failure points and making structural upgrades.
Durability and performance often come down to who made the part, not what label is on it. That’s why it’s essential to source from reliable companies with a strong track record, not just the one with the lowest price tag.
Myth #2: “They Won’t Fit or Function Properly”
This is one of the biggest concerns buyers have: What if it doesn’t fit? No one wants to delay a job because a replacement part won’t install properly. However, in today’s aftermarket world, poor fitment is no longer as prevalent as it once was.
Many aftermarket parts are manufactured using advanced modeling and digital measurement tools to ensure they match OEM dimensions exactly. As long as the supplier is reputable (like We-Attach or others with strict internal standards), fit and function are rarely an issue.
A good habit is to cross-reference OEM part numbers and review any dimensional specs before placing an order. When in doubt, it’s best to reach out to the supplier with questions. Getting it right upfront saves time and frustration later.
Myth #3: “Using Aftermarket Parts Voids My Warranty”
Many equipment owners worry that choosing an aftermarket part might void their warranty coverage. But here’s the good news: simply using an aftermarket component doesn’t automatically void your warranty.
In the U.S., the Magnuson-Moss Warranty Act protects consumers from this exact situation. Manufacturers cannot cancel your warranty simply because you didn’t use their branded parts, unless they can prove that the aftermarket component caused the issue.
What matters is whether the part performs as intended. To be safe, review the fine print on your warranty and contact your dealer for clarification. In most cases, you’re free to choose the best part for the job, as long as it’s properly installed and not the root cause of a failure.
Myth #4: “They Don’t Last as Long as OEM Parts”
There’s a strong belief that OEM equals a longer life. But lifespan is about much more than branding. Materials, artistry, and application all play a bigger role than the name on the box.
High-quality aftermarket parts often utilize the same materials as OEM ones, sometimes even superior ones. Steel alloys, hardened wear surfaces, and exact tolerances are standard with well-made components. Some manufacturers even enhance longevity by addressing weak points identified in the original designs.
It’s also worth noting that even the best part won’t last long if it’s installed poorly or not maintained. The right part, combined with proper handling and service, can easily meet or exceed the expected lifespan of OEM alternatives.
Myth #5: “Aftermarket Parts Are Hard to Source and Support Is Lacking”
This myth persists from a time when aftermarket parts were more challenging to find and sellers offered limited support. But the market has evolved. Today, many suppliers provide fast lead times, global shipping, and responsive customer service.
Reputable companies like We-Attach provide product documentation, technical assistance, and order tracking. Many even include live chat, detailed spec sheets, and real-time inventory updates online, making it easier to order with confidence.
Support doesn’t stop at the sale either. From returns to installation help, dependable suppliers treat aftermarket parts with the same level of professionalism you’d expect from OEM sources.
Conclusion: Making Informed Decisions for Your Equipment
The aftermarket parts industry has changed, and so should the perception around it. The notion that these parts are of low quality, ill-fitting, or poorly supported is outdated.
With the right supplier, such as We-Attach, aftermarket parts offer excellent value, long-lasting performance, and faster availability compared to many OEM channels. For fleet managers and procurement teams, they’re an innovative tool in the toolbox.
Before your next purchase, take the time to compare options, ask questions, and look beyond old assumptions. There are better choices out there; you just need to know where to look.
