OEM vs. Aftermarket Parts for Your Car: How to Choose


Recommended Posts

When selecting parts for a car repair, it pays to know the differences between original and aftermarket parts. Whenever possible, get estimates for both.

OEM vs. Aftermarket Parts for Your Car

Choosing between original and aftermarket car parts — and even used parts of either type — is all about squaring your priorities with your budget.

You’ll have different options depending on the part and the shop. And the best choice will depend on whether you’re trying to keep repairs cheap, restore your car’s appearance after a wreck or soup up your ride.

Before we get into that, here are the key differences:

Original equipment manufacturer (OEM) parts match those that came with your car, and are of the same quality as its original parts. They’re also the most expensive.
Aftermarket parts are cheaper, and made by other manufacturers — often several, giving you more options.
Used parts may have a bit of wear and tear, but should be inspected or rebuilt to ensure they’ll work. These are the cheapest option.

Choosing between aftermarket and OEM parts

Your decision will depend on the type of repair and the quality and price of the parts. Always look for parts that come with a warranty, even if they’re OEM, so you’ll be protected in case they fail.

Auto body repairs

Some aftermarket parts may be OK for

, but others won’t be as good, says Michael Calkins, manager of technical services at AAA. “There’s a lot of variation in quality.” For example, he says, aftermarket parts often don’t have the same level of rustproofing as original parts, fit and finish don’t match, or panels don’t align properly.

Ultimately your decision will depend on the type of repair and the quality and price of the parts.

If OEM parts are used in auto body repair, the car should look and work exactly as it did before the damage, because everything will match up. OEM parts are also crash-tested, unlike many aftermarket parts.

Aftermarket parts come at varying price points and levels of quality, but because they are cheaper, insurance companies often prefer them. If you want OEM parts but are dealing with an insurer that wants the shop to use aftermarket parts, ask to pay the difference.

“There’s also the option of used parts, depending on the age of the vehicle,” Calkins says. “It may be cheaper than an aftermarket part but still have all of the original quality.”

Mechanical repairs

A used part, whether it’s OEM or aftermarket, can really save money on repairs under the hood, so long as it’s inspected first and warrantied. And some aftermarket companies reverse-engineer their products to be even better than OEM versions.

Some companies reverse-engineer aftermarket parts to be even better than OEM versions.

For example, many car buffs will tell you that you can get heavy-duty shocks and struts or brake pads that are made of stronger materials. Scan some reviews online, or talk with your mechanic if you’re not sure whether an aftermarket part could be an upgrade.

Adding some extras

If you’d like to modify your ride by adding something like a backup camera or back-seat TV screen, you’ll probably be looking for aftermarket parts. Certain aftermarket upgrades could increase

. This is especially true for improvements like a better sound system or alloy wheels, rather than mechanical repairs.

Who provides OEM or aftermarket parts?

The options you’ll have for parts depends on the nature of the repairs and what type of shop you take your car to:

    • Dealership repair shops will offer only OEM parts — they have no reason to offer a cheaper product from a competitor
    • link hidden, please login to view
       may be able to offer you a choice between OEM and aftermarket parts
    • Independent garages that specialize in your type of vehicle will likely have both, but with quicker access to OEM parts, including used OEM parts, which can really save you
    • Auto body shops can offer both, but if your collision repair is part of an insurance claim, the insurer will likely prefer aftermarket parts to save money

Depending on the job, the cost of OEM versus aftermarket parts varies. Whenever you’re given the choice, ask to see estimates for both so you can weigh your options.

I prefer to buy aftermarket car parts instead of OEM due to the fact that aftermarket car parts are less costly as compared to OEM. Choosing aftermarket car parts gives you a variety of options and they are easily available, whereas OEM parts on the other hand are not readily available and in order to purchase an OEM part you will have to contact your care manufacturer. Lastly, and most importantly, aftermarkets parts have been known to perform better then the original parts in certain cases.

      Truck Brake Pads Thickness
      The recommended thickness of truck brake pads may vary depending on the specific brand and model of the truck, as well as the type of braking system installed.
      However, regardless, our principle is to replace them when the thickness is less than 3 to 4mm, which plays a protective role in our safety. The new thickness of truck brake pads is typically 30 millimeters. As the brake pads wear from use, their thickness gradually decreases. Once the brake pads reach the recommended minimum thickness, they should be replaced to ensure optimal braking performance and safety.

      We all know that the basic formulas for brake pads nowadays are ceramic, low metallic, and semi-metallic brake pads. However, for truck brake pads, we strongly recommend using the semi-metallic formula. The reason is that semi-metallic brake pads have a much higher wear resistance compared to low metallic and ceramic formulas, even though ceramic formulas are more friendly to the brake rotor.

      The phenomenon that two objects move relative to each other to produce motion resistance between their contact surfaces is called friction, which is called friction. The existence of friction not only increases the power consumption, but also causes the wear of parts' contact surfaces. Therefore, lubricating oil is usually used between the relative moving surfaces of automobile parts to reduce friction. Failure of automotive parts 75% is caused by friction.
      Friction can be divided into dry friction, liquid friction, boundary friction and mixed friction according to the lubrication state of the parts.
      (1) dry friction
      The friction between the frictional surfaces without any lubricating medium is called dry friction.
      When the parts are in the state of dry friction, the surface of the parts is abraded sharply, so the surface of the moving parts of the automobile should avoid the occurrence of dry friction as far as possible.
      Dry friction and boundary friction are the main friction between the upper part of cylinder wall and piston ring. Dry friction will occur when the journal and bearing are subjected to impact load in the working process.
      (2) liquid friction
      Two the friction of the friction surface when the lubricant is completely separated is called liquid friction.
      In liquid friction, the two friction surfaces are completely separated by a layer of lubricating oil film with a thickness of 1.5-2.0um, which avoids direct contact between the working surfaces of the two parts. Friction only occurs between the lubricating fluid molecules, so the friction resistance is very small, and the wear of the parts is very slight.
      Most of the relative motion parts of a car are carried out under the condition of liquid friction (for example, crankshaft and bearing).
      (3) boundary friction
      Two friction surface separated by a very thin boundary film is called boundary friction.
      The oil film thickness is usually below 0.1um. Friction only occurs between the outer molecules of the boundary film, reducing the friction and wear of the parts. But its thickness is very small, and it is easy to be destroyed by impact and high temperature, so it is not as reliable as liquid friction.
      For example: between cylinder wall and piston ring; if the work crankshaft and journal between the insufficient supply of lubricant, easy to produce boundary friction.
      (4) Mixed friction
      The friction between two friction surfaces in the presence of dry friction, liquid friction and boundary friction is called mixed friction.
      In the actual working state, the parts usually work under the mixed friction state, and the friction state varies with the working conditions.
