Dorman Auto Parts Review: Is It Worth It?

If you own a car out of warranty, you have likely felt the sticker shock of a dealership repair quote. The mechanic tells you a simple plastic knob or a window motor costs hundreds of dollars because they only use “genuine” parts. This is usually the moment you start frantically searching online for alternatives and stumble upon Dorman Auto Parts. They are everywhere—AutoZone, Amazon, RockAuto—promising to fix your problem for a fraction of the price. But are they safe?

In this review, I am going to analyze Dorman’s massive catalog of aftermarket solutions, specifically focusing on their “OE Fix” line and general replacement parts. I will compare them to the original equipment manufacturer (OEM) to see if the savings are worth the potential trade-offs in quality. Whether you are a DIY mechanic or just trying to save money at the shop, this guide will help you decide if Dorman is the right choice for your vehicle. For the best selection and warranty support, buying through major retailers like Amazon or local parts stores is usually the safest bet.

My Experience With Dorman Auto Parts

My first significant encounter with Dorman happened a few years ago when the driver’s side window on my older SUV decided to quit halfway down during a rainstorm. I called the dealership, and they quoted me nearly $400 for the regulator assembly alone, not including labor. That felt astronomical for a car that was already showing its age, so I decided to tackle the repair myself. I went to the local auto parts store and picked up a Dorman window regulator for about $80—a massive difference in price.

The packaging was straightforward: a simple orange and black box with the part inside.

I was initially worried that the “universal” nature of aftermarket parts would mean I’d have to drill new holes or fight with the fitment.

However, I was pleasantly surprised. The Dorman regulator looked almost identical to the factory one I pulled out of the door panel, except for a few subtle differences in the plastic clips which actually looked a bit beefier than the originals.

Installation took me about an hour. The bolt holes lined up perfectly with the door frame, which is often the biggest headache with cheaper aftermarket brands. I plugged in the motor, and the window rolled up and down with a solid, confident speed. It didn’t sound strained or whiny, which can sometimes happen with inferior electric motors.

Since that first repair, I have used Dorman for several other “annoyance” fixes. I replaced a cracked intake manifold on a Ford truck using their “OE Fix” version, which had reinforced aluminum coolant crossovers instead of the plastic ones that originally failed. That specific part actually felt like an upgrade rather than just a replacement. I also swapped out some blend door actuators that were clicking behind my dashboard.

However, it hasn’t all been perfect. I once bought a Dorman abs sensor that failed within six months, forcing me to do the job twice. This taught me that while their hard parts and structural fixes are often excellent, their complex electronics can sometimes be hit-or-miss. Overall, my experience has been overwhelmingly positive for the price, especially when dealing with common mechanical failures where the original manufacturer dropped the ball. It transformed expensive, dread-inducing repairs into manageable weekend projects that saved me thousands of dollars over the years.

Pros Of Dorman Auto Parts

When you dive into the world of aftermarket parts, Dorman stands out for several specific reasons that go beyond just being “the cheap option.” Here is why they have become a staple for mechanics and DIYers alike.

The “OE Fix” Innovation Line: This is arguably Dorman’s strongest selling point and what separates them from generic copycats. Many factory parts fail because of inherent design flaws—like using plastic in high-heat areas or weak internal gears. Dorman identifies these high-failure parts and re-engineers them to be stronger than the original. For example, they offer aluminum intake manifolds to replace plastic ones that crack, and metal heater hose connectors to replace brittle factory plastic. In these cases, you aren’t just saving money; you are actually upgrading the vehicle with a part designed to last longer than the one the car was built with.
Massive Availability And Accessibility: You never have to look far to find a Dorman part. They have an incredibly vast distribution network, meaning you can find their products in almost every auto parts store in North America, including AutoZone, O’Reilly, and Advanced Auto Parts. This is crucial when your car breaks down on a Saturday afternoon and you need to get it running for work on Monday. Unlike specialized OEM parts that might have to be ordered from a warehouse in Germany or Japan and take weeks to arrive, Dorman parts are usually sitting on a shelf down the street. This convenience factor is a huge “pro” for anyone who relies on their vehicle daily.
Significant Cost Savings Over Dealer Parts: The price difference between Dorman and the “Genuine” dealer box is often staggering. It is not uncommon to find a Dorman control arm or window motor for 50% to 70% less than the OEM equivalent. For older vehicles where the car’s value doesn’t justify a $1,000 repair bill, Dorman makes it economically viable to keep the car on the road. This affordability allows people to perform preventative maintenance they might otherwise skip if they were forced to pay premium dealer prices. You get a functional, safe repair without draining your savings account.
Limited Lifetime Warranty: Dorman backs the vast majority of their parts with a Limited Lifetime Warranty. This provides a massive safety net for the consumer. If the part fails—whether it is a week later or five years later—you can typically walk into the retailer where you bought it and swap it for a new one for free. While nobody wants to do a job twice, knowing that you won’t have to pay for the part again offers peace of mind. This warranty policy suggests that the company is confident enough in their quality control to stand behind their products for the long haul.

Cons Of Dorman Auto Parts

While Dorman is a lifesaver for the budget, it is important to be realistic about what you are buying. They are an aftermarket supplier, and with that territory comes certain compromises and risks that you need to be aware of.

Inconsistent Quality Control On Electronics: While their mechanical parts are generally solid, their track record with sensors and complex electronics is mixed. Many professional mechanics will hesitate to use Dorman for critical sensors like Crankshaft Position Sensors or Mass Air Flow sensors because they require extreme precision. A Dorman sensor might work out of the box but could drift out of spec or fail prematurely compared to a Bosch or Denso unit. This “hit or miss” reliability with electronics can lead to frustration if you end up chasing a check engine light that comes back a few months later. For purely electronic repairs, the OEM part is often the safer, albeit more expensive, bet.
Fitment Can Sometimes Be Imperfect: Because Dorman reverse-engineers their parts rather than having the original blueprints, there can be slight variances in fit. You might encounter a bolt hole that is a fraction of a millimeter off, requiring you to use a little extra force or “persuasion” to get it lined up. Sometimes the finish or the texture of cosmetic parts (like door handles or window switches) doesn’t perfectly match the rest of your interior. While the part will function, it might not have that crisp, “snaps-into-place” feeling that a factory part has. This can add time and frustration to what should be a simple installation process.
Perception Of Lower Durability For Heavy Duty Use: For standard daily driving, Dorman parts are usually more than adequate. However, if you are driving a heavy-duty work truck or a performance vehicle, some Dorman suspension or chassis parts might not hold up as well as premium brands. The rubber bushings used in their control arms or sway bar links may degrade faster than the high-grade rubber used by OEM or performance aftermarket brands like Moog. If you live in an area with harsh roads or tow heavy loads, you might find yourself replacing suspension components more frequently than you would like.
Country Of Origin Confusion: Dorman is an American company, but like most massive manufacturing entities, they source parts globally. A significant portion of their inventory is manufactured in China or other overseas facilities to keep costs down. This isn’t inherently bad, as Chinese manufacturing can be excellent, but it does lead to variability. One batch of parts might be high quality, while another batch from a different supplier might be lesser. If you are a purist who prefers parts made in the USA, Japan, or Germany, seeing “Made in China” on the box might be a disappointment.

Maintenance Tips For Dorman Auto Parts

Since Dorman parts are replacements, “maintenance” largely revolves around proper installation and inspection to ensure they last as long as possible. Here is how to get the most life out of your new parts.

Verify The “OE Fix” Application: Before you buy, spend a few minutes researching if Dorman offers an “OE Fix” version of the part you need. Sometimes they sell a standard replacement and an upgraded version. You always want to opt for the upgraded design (often denoted with different part numbers or descriptions like “aluminum housing”). This ensures you aren’t just putting the same flawed design back into your car that failed in the first place. Checking forums or their website can save you from a repeat failure down the road.
Use Anti-Seize And Dielectric Grease: Because aftermarket parts might use different metal alloys or coatings, protecting them during installation is key. For any suspension or chassis part, apply anti-seize to the threads (unless the manual says otherwise) to prevent rust-jacking, especially if you live in the Rust Belt. For any electrical connector or sensor, use a dab of dielectric grease on the contacts. This prevents moisture corrosion, which is a common killer of aftermarket electronics. These small steps can significantly extend the lifespan of the part and make future removal easier.
Torque To Specification, Do Not Guess: One of the biggest reasons aftermarket parts fail is improper installation torque. Dorman parts are designed to handle the factory torque specs, but over-tightening can crack plastic housings or strip threads, while under-tightening leads to rattles and wear. Always use a torque wrench and look up the specific ft-lbs or in-lbs required for that specific bolt. Do not assume “tight enough” is good enough, especially with gaskets and plastic intake manifolds. Proper clamping force is essential for a long-lasting seal.
Inspect Rubber Boots And Seals Regularly: If you install Dorman suspension parts like ball joints or tie rods, keep an eye on the rubber dust boots. The rubber quality can vary, and if a boot tears, grease escapes and grit gets in, destroying the joint rapidly. Inspect these boots at every oil change. If you catch a small tear early, you might be able to repair it or regrease it before the joint itself is ruined. For window seals or door handles, keeping them clean and using a silicone spray can prevent the plastic from becoming brittle in the sun.

Comparison with Other Brands

Dorman is a giant, but it isn’t the only player in the game. Understanding how they compare to specific competitors helps you make the right choice for each specific repair.

OEM (Original Equipment Manufacturer – Ford/GM/Toyota): This is the baseline standard—the parts your car was built with. Comparison: OEM parts guarantee perfect fitment and are generally the most reliable for complex electronics and sensors. However, OEM parts are notoriously expensive and often suffer from “planned obsolescence” or design flaws that are never updated. Dorman is almost always cheaper and, in the case of their “OE Fix” line, can actually be superior to the OEM design by eliminating the flaw (like replacing plastic with metal). Choose OEM for critical engine sensors; choose Dorman for mechanical parts, handles, and known failure points where the OEM design sucks.
Moog Suspension Parts: Moog is widely considered the premium standard for aftermarket suspension and chassis components (ball joints, tie rods). Comparison: Moog creates parts that often exceed OEM standards with features like greaseable joints and “Problem Solver” technology. Dorman suspension parts are generally considered “standard replacement” grade—good for a daily driver but not as robust as Moog. Moog parts are typically more expensive than Dorman. If you are rebuilding the front end of a truck you plan to keep forever, Moog is likely the better investment. If you just need to pass a safety inspection on a commuter car, Dorman will do the job perfectly fine for less money.
Standard Motor Products (SMP): SMP is a massive competitor that focuses heavily on engine management and electronics. Comparison: SMP is often regarded as having slightly higher quality control for sensors, switches, and ignition components than Dorman. They manufacture many of their parts in high-tech facilities that rival OEM quality. Dorman is more of a “generalist”—they do everything from window motors to lug nuts. SMP is a “specialist” in engine electronics. If you need an ignition coil, fuel injector, or obscure sensor, SMP is often the preferred choice among mechanics over Dorman, though Dorman is often easier to find in stock locally.
