If you own a Chevrolet and need repairs or maintenance, choosing the correct parts is crucial. Should you buy genuine GM parts or save money by buying aftermarket alternatives? Unfortunately, cheaper components often cost more in the long run. Genuine GM parts may impact your wallet initially, but they’re manufactured for your vehicle’s make and model. They fit properly, last longer, and keep your Chevy performing at its best. Our experts at Eskridge Chevrolet in Guthrie, Oklahoma, explain why original equipment manufacturer (OEM) parts are the way to go.

What Sets Genuine GM Parts Apart?
The difference between GM parts and aftermarket parts is huge. We’re talking about performance, how long they last, and whether your car malfunctions after the repair.
Quality and Reliability You Can Count On
GM parts undergo a series of rigorous quality-controlled tests to guarantee they meet the highest standards. They’re manufactured using high-quality materials that meet or exceed original factory specifications, so you can trust they’ll hold up to the challenges of everyday driving. Aftermarket parts might cost less upfront, but they often don’t offer the same reliability or durability as genuine GM parts. That means you’ll be replacing them more often, costing you more over time.
Perfect Fit and Compatibility Guaranteed
Nothing is more annoying than trying to fit a part that won’t line up. Genuine GM OEM Chevrolet parts are the same as those fitted to vehicles in the factory. Aftermarket parts are manufactured to fit a number of different cars — they fit, but not perfectly, so they wear out faster and need replacing more often. Why risk it?
Warranty Coverage
When something goes wrong with your car, it’s reassuring to know you’re covered. Genuine GM components include warranty coverage, giving you peace of mind if the part itself fails.
No Tech Headaches
Modern Chevys are computers on wheels. From the engine and transmission to the electrical system and sensors, everything must work seamlessly for the best driving experience. That’s why it’s crucial to use genuine GM parts when repairing or maintaining your vehicle. Otherwise, you risk causing more damage.

Key Repairs: Where Genuine GM Parts Are Critical
Some fixes call for genuine GM OEM components — your safety depends on it.
Brakes
Don’t mess with your brakes. GM parts are strong enough to stop your Chevy consistently and just when you need them. Cheap brake parts might stop your car, but they won’t feel right and may not be good enough when you’re trying to avoid an accident.
Engine
Your engine has many moving parts with zero room for error. They endure extreme heat, intense pressure, and chemical exposure. Genuine GM engine parts are made from materials that can withstand these conditions, but we can’t say the same for aftermarket parts.
Electronics
Your Chevrolet’s computer controls engine timing, transmission shifts, safety features, and more. Genuine GM electronic parts are programmed specifically for your car’s setup. Generic electronic parts might work initially, but they often cause strange problems later. For example, a single faulty sensor or switch can trigger warnings on multiple systems.
Transmission
There’s significant wear and tear on transmission parts. If something fails, replacing it with a genuine GM part makes the rest of your transmission last longer. Get this wrong, and you’re looking at a complete transmission rebuild.
How To Get the Right Part for Your Chevy
Finding the correct GM component consists of a few simple steps. Skip these, and you might end up with the wrong component. Here’s how to nail it every time:
- Check your owner’s manual: Your owner’s manual has a list of essential maintenance items, complete with part numbers. This prevents ordering the wrong item.
- Find your vehicle identification number (VIN): That long string of numbers by your dashboard or door has all the info about your Chevy. With the VIN, you can easily match parts.
- Talk to our technicians: Our certified techs know Chevrolet systems inside and out. They’ll steer you in the right direction if you’re not sure, and they’ll often spot related components that might need repair.
