The Importance of Using OEM Parts in Repairs: Protecting Your Vehicle and Your Investment

When it comes to keeping your vehicle performing at its best, few decisions are as important as choosing the right replacement parts. Whether you’re dealing with a collision repair, mechanical failure, or routine maintenance, your decision to use OEM parts (Original Equipment Manufacturer) versus aftermarket parts can impact your vehicle’s safety, warranty, performance, and long-term value. 

At Kraig Chevrolet in Oskaloosa, IA, we believe in providing our customers with reliable, factory-certified repairs. That’s why we strongly recommend using genuine Chevrolet OEM parts for all service and repair work. 

In this blog, we’ll dive deep into: 

• What OEM parts are 
• How they differ from aftermarket options 
• Why OEM parts protect your vehicle investment 
• When aftermarket may be okay — and when it's risky 

OEM (Original Equipment Manufacturer) parts are components made by the same manufacturer that produced the original parts in your Chevrolet vehicle. They are designed specifically for your make, model, and trim level — ensuring precise fit, optimal performance, and full compatibility with existing systems. 

Think of OEM parts as the "blueprint-perfect replacement" for your car. Every sensor, nut, and panel is built to factory specifications, using the same materials and engineering standards as your vehicle’s original parts. 

A front bumper from Chevrolet for a 2025 Silverado will have: 

• The same fitment as the original 
• The correct color code for factory paint 
• Pre-cut space for sensors or grille mounts 
• Material tested for crash impact and temperature resistance 

By contrast, aftermarket parts are made by third-party companies and may vary in shape, quality, and performance. 

While aftermarket parts may be less expensive upfront, the risks often outweigh the cost savings — especially in critical systems like brakes, airbags, or engine components. 

OEM parts are more than just brand-name labels — they’re essential to preserving the structural integrity and safety of your vehicle. Here's how: 

OEM parts are crash-tested as part of the entire vehicle structure. Aftermarket parts don’t go through the same rigorous testing, which can lead to compromised protection in an accident. 

Modern Chevrolets are filled with tech — parking sensors, blind-spot monitors, forward-collision alerts — and each of these relies on precise part positioning. A slightly misaligned aftermarket bumper or fender can cause malfunctioning safety alerts or false warnings. 

OEM parts are made of high-strength steel, OEM-certified plastics, or specialty alloys — all meeting Chevrolet’s engineering standards. Aftermarket materials often lack rustproofing, insulation, or crash durability. 

For safety-conscious drivers and families, this alone makes OEM a smart choice.

One of the most overlooked issues when choosing aftermarket parts is the risk to your factory warranty. 

• If a non-OEM part causes failure in another system, warranty coverage can be denied. 
• You may have to pay out of pocket for future repairs or diagnostics. 
• Certain coverage programs (like GM’s Powertrain Warranty) require OEM parts for continued eligibility. 

When you use genuine Chevy parts from a dealership like Kraig Chevrolet, you not only maintain compliance but also benefit from part-specific warranties, sometimes lasting up to 24 months or longer. 

At our Chevrolet Service and Parts Department, we take pride in doing things right the first time. 

• OEM-certified parts sourced directly from General Motors 
• Factory-trained and ASE-certified technicians 
• Compliance with all GM service protocols 
• Full documentation to protect resale and warranty 

We offer everything from replacement brake rotors and batteries to complex engine and transmission components, all backed by Chevrolet’s parts warranty and our local commitment to service excellence. 

While we always recommend OEM, there are a few cases where aftermarket parts might make sense — if chosen carefully: 

• Cosmetic parts like wiper blades, interior trim, or floor mats 
• Upgrades such as performance exhaust systems (when warranty is not a concern) 
• Budget repairs on older vehicles not under warranty 

However, it’s vital to consult your service advisor to ensure the part won't compromise safety or performance. 

📘 Pro Tip: Stick to OEM or Tier-1 aftermarket brands with solid reputations, such as Bosch, Denso, or AC Delco (which is owned by GM and often OEM).

When it comes time to sell or trade in your vehicle: 

• Dealers and buyers prefer cars with full OEM service history

1. What are OEM parts and why are they better than aftermarket? 

A: OEM (Original Equipment Manufacturer) parts are made by the same company that built your vehicle’s original components, ensuring a perfect fit, factory-grade materials, and warranty compatibility. Unlike aftermarket parts, OEM components are engineered for your exact make and model, offering better durability, safety compliance, and long-term performance. 

2. Do OEM parts affect my vehicle’s warranty? 

A: Yes — using OEM parts helps maintain your factory warranty. Many automakers, including Chevrolet, may deny warranty claims if a failure is caused by an aftermarket part. OEM parts from dealerships like Kraig Chevrolet are fully compliant with GM's warranty policies, giving you peace of mind during future service needs. 

3. Are OEM parts more expensive than aftermarket parts? 

A: OEM parts typically cost more upfront, but they offer superior long-term value. They reduce the risk of poor fitment, premature failure, and costly rework. Plus, they come with manufacturer-backed warranties — saving you money in the long run by protecting your vehicle's integrity and resale value. 

4. Can I request OEM parts during a repair or insurance claim? 

A: Absolutely. You can and should request OEM parts during service or insurance-related repairs. While some insurers default to aftermarket components, most will approve OEM parts upon request, especially if you’re repairing a newer vehicle. Your dealership can help advocate for OEM use in insurance claims.
