After being involved in a collision, one of the most important decisions you'll face is what type of parts to use in your vehicle's repair. While your insurance company might push for aftermarket parts to reduce costs, it's essential to understand what these parts are and how they might affect your vehicle's performance, safety, and value. At First Aid Collision, we believe an informed customer makes better decisions, so we've created this comprehensive guide to aftermarket parts.
1. What Are Aftermarket Parts?
Aftermarket parts are any parts used to repair your vehicle that weren't made by the original equipment manufacturer (OEM). While the term "aftermarket" might sound negative, these parts actually span a wide spectrum of quality and price points.
In the collision repair industry, aftermarket parts fall into several categories:
- New aftermarket parts: Made by third-party manufacturers, designed to function like OEM parts
- Recycled parts: Used OEM parts salvaged from vehicles no longer on the road
- Remanufactured parts: OEM parts that have been rebuilt to meet certain specifications
- Certified aftermarket parts: Third-party parts that have passed certification testing
Each type has its place in the auto body repair ecosystem, but not all are created equal when it comes to quality, fit, and safety.
2. OEM vs. Aftermarket: Understanding the Key Differences
When your vehicle enters our shop at First Aid Collision, we often discuss parts options with our customers. This conversation is crucial because the parts decision can affect everything from how your vehicle looks to how it performs in a subsequent collision. Here's what you need to know about the differences:
OEM Parts
Original Equipment Manufacturer parts are made by your vehicle's manufacturer or their authorized suppliers. For example, if you drive a Toyota, OEM parts would come from Toyota or a supplier authorized by Toyota to produce parts to their exact specifications.
These parts:
- Are identical to the parts that came with your vehicle when it was new
- Typically come with a manufacturer's warranty (often 12 months or more)
- Undergo rigorous testing to meet manufacturer specifications for safety and performance
- Usually cost more than aftermarket alternatives (sometimes 50-100% more for certain components)
- Maintain your vehicle's original quality standards and specifications
- Are more likely to maintain the vehicle's resale value
- Often provide better corrosion protection due to matching factory finishing processes
- Feature identical mounting points and electrical connections, ensuring proper fit
Most luxury vehicle owners and leased vehicles benefit from using OEM parts to maintain their warranty conditions and value. Additionally, complex modern vehicles with integrated electronic systems often function best with OEM parts that are designed to work with these proprietary systems.
Aftermarket Parts
These non-OEM parts vary widely in quality and price, making them a more complex choice. Aftermarket parts are produced by independent manufacturers like LKQ, Keystone, or Dorman, rather than by the company that made your vehicle.
Aftermarket parts:
- May be designed through reverse engineering of OEM parts, sometimes improving on original designs
- Often cost 20-40% less than OEM parts, providing significant savings on major repairs
- Can have varying levels of quality from "economy" to "premium," with corresponding price points
- May or may not come with warranties (some premium aftermarket parts actually offer longer warranties than OEM)
- Fit and finish may differ from OEM standards, sometimes requiring additional adjustment during installation
- Can offer more options and features not available from the original manufacturer
- May be more readily available than OEM parts, reducing repair time
- Might use different materials than OEM (such as different grades of steel or plastics)
3. The Pros of Using Aftermarket Parts
There are legitimate reasons why aftermarket parts remain popular in the collision repair industry:
Cost savings are the most obvious benefit. Aftermarket parts can significantly reduce repair costs, which can be especially important if you're paying out of pocket or have a high deductible. For example, an aftermarket fender for a popular sedan might cost $150 compared to an OEM version at $400 – a difference that quickly multiplies across multiple parts in a major repair.
Availability is another advantage. While OEM parts might need to be ordered and shipped from distant warehouses or distribution centers, many aftermarket parts are readily available from local suppliers, potentially reducing your repair time from weeks to days. This widespread availability becomes especially important for older vehicles where OEM parts may be difficult to source.
Variety and options can be beneficial. In some cases, aftermarket manufacturers have improved upon original designs or offer upgraded versions of certain parts. For example, you might find aftermarket bumpers with additional reinforcement or headlights with improved illumination technology that weren't available when your vehicle was manufactured.
Competition in the marketplace keeps overall repair costs in check, benefiting consumers in the long run. Without aftermarket options, OEM manufacturers would have a monopoly on replacement parts, potentially leading to higher prices across the board.
Reduced total loss declarations can sometimes result from the availability of lower-cost aftermarket parts. In cases where repair costs are approaching a vehicle's value, using more affordable parts can sometimes prevent an insurance company from declaring the vehicle a total loss.
Customization options are more prevalent in the aftermarket world. If you're looking to personalize your vehicle during the repair process, aftermarket parts often provide designs and features not available from the original manufacturer.
4. The Potential Downsides of Aftermarket Parts
Despite their advantages, aftermarket parts come with considerations that every vehicle owner should understand:
Quality concerns are legitimate. The truth is that some aftermarket parts simply don't match OEM quality in terms of materials, durability, or precision manufacturing. While premium aftermarket brands often produce excellent parts, budget options might use thinner metals, lower-grade plastics, or simplified designs that affect longevity and performance.
Fit issues can arise, as aftermarket parts may not match the exact specifications of your vehicle. Even small variances of a few millimeters can affect how parts align or function together. This can lead to problems like uneven panel gaps, wind noise, water leaks, or excessive vibration. At First Aid Collision, our technicians sometimes need to make minor modifications to aftermarket parts to achieve proper fitment, which can add labor time to repairs.
Safety considerations are paramount. While many exterior cosmetic parts pose minimal safety risks, structural components directly impact your vehicle's crashworthiness. Modern vehicles are designed with specific crumple zones and impact-absorbing structures. Aftermarket parts that don't precisely match OEM specifications might alter how energy is dispersed in a collision, potentially affecting occupant safety.
Warranty implications are worth considering. Using certain aftermarket parts might affect your vehicle's warranty in some circumstances. While the Magnuson-Moss Warranty Act prevents manufacturers from voiding warranties simply because aftermarket parts were used, if an aftermarket part causes damage, related repairs might not be covered.
Resale value can be impacted. Vehicles repaired with OEM parts typically command higher resale values than those with aftermarket components. This is especially true for luxury vehicles or models known for their reliability and longevity. When selling or trading in your vehicle, a repair history showing OEM parts can be a significant advantage.
Performance differences can sometimes be noticeable. This is particularly true for components like sensors, electronic modules, and parts that affect handling or braking. For example, aftermarket brake components might provide adequate stopping power but could feel different under foot or produce more noise than OEM equivalents.
Finish and appearance variations can be an issue, especially with visible parts like bumpers, fenders, and hoods. The paint formulation, texture, and color matching might not be identical to your vehicle's original finish, sometimes resulting in slight color variations that are noticeable in certain lighting conditions.
5. How Aftermarket Parts Affect Insurance Claims
Understanding how parts selection impacts your insurance claim is crucial:
Most insurance companies prefer aftermarket parts because they reduce claim costs. In fact, many policies specifically state that non-OEM parts may be used in repairs. However, in North Carolina, there are laws that protect your right to choose where to repair your vehicle after a collision, including anti-steering laws that prohibit insurance companies from requiring you to use a specific repair shop.
While your insurance might only pay for aftermarket parts, you typically have the right to request OEM parts if you're willing to pay the difference. At First Aid Collision, we help our customers navigate these conversations with their insurance providers to ensure they understand their options.
6. How to Choose Quality Aftermarket Parts
If you decide that aftermarket parts make sense for your situation, here are tips for ensuring you get quality components:
- Look for certified parts that have been tested by independent organizations like CAPA (Certified Automotive Parts Association) or NSF (National Sanitation Foundation). These certification programs test aftermarket parts for material composition, strength, fit, finish, and function to ensure they meet quality standards comparable to OEM.
- Check warranties offered with the parts. Quality aftermarket manufacturers stand behind their products with solid warranty coverage. Some even offer lifetime warranties that exceed OEM coverage.
- Ask about the manufacturer's reputation with your repair shop. At First Aid Collision, we've worked with countless parts over the years and can recommend aftermarket brands that have consistently performed well.
- Consider the part's function – cosmetic parts (like trim pieces) are generally lower risk than structural components. For safety-critical parts like airbag sensors, structural reinforcements, or energy-absorbing components, OEM parts are often worth the additional cost.
- Request to see the parts before installation if you have concerns. A quality repair shop will be transparent about the parts they're using and should be willing to show you the components before they're installed.
- Research online reviews of specific aftermarket brands for your vehicle make and model. Owner forums and automotive communities often discuss which aftermarket parts perform well for particular vehicles.
- Understand tier levels within aftermarket parts. Many manufacturers offer good-better-best options, with corresponding price points. Premium-tier aftermarket parts often approach or match OEM quality while still offering some cost savings.
- Consider the vehicle's age and value when making parts decisions. For newer, high-value vehicles, OEM parts might better preserve long-term value, while older vehicles might benefit more from the cost savings of quality aftermarket components.
- Ask about adjustment time required for installation. Some aftermarket parts might need additional fitting during installation. Understanding this can help you make a more informed decision about the true cost difference between OEM and aftermarket options.

8. Frequently Asked Questions About Aftermarket Parts
Can aftermarket parts void my car warranty?
No, simply using aftermarket parts cannot void your entire vehicle warranty. The Magnuson-Moss Warranty Act protects consumers from blanket warranty cancellations. However, if an aftermarket part directly causes damage, the manufacturer might deny coverage for that specific repair. For example, if an aftermarket engine component fails and damages your engine, the warranty might not cover those specific repairs, but would still apply to unrelated systems like your transmission or electrical systems.
Are aftermarket parts safe?
It depends on the part and its quality. Certified aftermarket parts from reputable manufacturers can be comparable to OEM parts in terms of safety. However, safety-critical components like airbag systems or structural parts are areas where many experts recommend OEM parts. At First Aid Collision, we evaluate safety implications for every part recommendation we make and will always prioritize your safety over cost savings.
Will my insurance company let me choose OEM parts?
Most standard insurance policies specify the use of aftermarket parts when available. However, you generally have the right to request OEM parts if you're willing to pay the difference in cost. Some insurers offer OEM endorsements for an additional premium. In North Carolina, insurance companies cannot require you to use a specific repair shop, giving you some leverage in parts negotiations. Our team can help explain your options and even communicate with your insurer on your behalf.
How can I tell if my vehicle has been repaired with aftermarket parts?
Ask your repair shop for a detailed parts list. Quality repair shops like First Aid Collision provide transparent documentation of all parts used in repairs. You can also look for visual clues like inconsistent panel gaps, color matching issues, or missing manufacturer logos on parts. Most aftermarket parts don't carry the vehicle manufacturer's branding that would appear on OEM components.
Are recycled OEM parts better than new aftermarket parts?
Recycled OEM parts were originally made by the vehicle manufacturer, so they may offer better fit and finish than some aftermarket options. However, their condition depends on the donor vehicle's age, mileage, and exposure to elements. Quality recycled parts from reputable salvage operations can be an excellent middle-ground option, offering OEM quality at a price point closer to aftermarket. The best choice depends on the specific part and its condition.
If I lease my vehicle, do I have to use OEM parts for repairs?
Most lease agreements don't specifically require OEM parts for repairs, but they do require the vehicle to be returned in good condition with any repairs performed to industry standards. Using quality parts (whether OEM or high-grade aftermarket) ensures you won't face excess wear-and-tear charges at lease-end. For leased vehicles, we often recommend OEM parts for exterior and visible components to avoid any concerns when you return the vehicle.
Do aftermarket parts affect my vehicle's resale value?
They can, especially for newer or luxury vehicles. Many car buyers and dealerships check vehicle history reports and may pay less for vehicles repaired with aftermarket parts. The impact is usually minimal for older vehicles or minor repairs, but can be significant for major structural repairs on newer models. If resale value is a priority, discussing this with your repair shop can help guide appropriate parts decisions.
How do I know if my aftermarket parts are certified?
Certified aftermarket parts will have a CAPA or NSF seal directly on the part. You can ask your repair shop to show you these certifications before installation. CAPA-certified parts, for example, undergo fit and finish testing, material composition analysis, and performance testing designed to ensure the part functions similarly to the OEM equivalent.
