Dorman products

[ItstheHOFF]

Has anyone had much experience with Dorman brand OEM parts? Just curious if their quality. They seem to be a fraction the price of certified gm parts so this family man is trying to save some money! Does the community use them often? Or do y’all swear against them?

I've used them a few times, and not had any issues. Here's an example.

I used to drive an '02 Expedition with the 5.4L V8. The OEM plastic intake manifold cracked at 150k miles. I replaced it with Dorman, which I found to be a better-made part than OEM. It was more heavily built, especially around the thermostat housing. All the factory brackets and clips fit perfectly. The only thing it didn't come with was the factory sound deadening foam on the underside. But I couldn't tell any difference in sound (and wouldn't have cared if there was a difference). Put 60k miles on it without issue before I sold the truck. Cost about half of OEM, if I recall correctly.

We see them all the time. Quality seems to depend on which parts you're talking about. Fuel line clips? Do it. ISS bearing? Steer clear. And so forth....

I have around $65k in "dorman" products listed on ebay, quite honestly most of it is a good product, there is a few things I would stray away from in there product line, like the plastic heater hose connectors, yet one of there heater hose connectors is made of aluminum rather than plastic so it is better than oem. It really can depend on the particular part sometimes.

What about their driveshafts? I'm still shopping for a replacement for my Tahoe and not sure what brand to go with. I just need it to be able to handle a little over 500 horsepower with my future plans for it.

I think that a very general consensus is that if it's a difficult part to replace, use AC Delco or an OE brand. Like @Doubeleive mentioned, Dorman dependability can vary by part.

I have had much more good luck than bad luck with Dorman. Definitely one of the brands at the top of my list.

I’ve had not so great luck with several Dorman products. I prefer OEM unless it was a low budget car that I was selling

If it’s hard to replace or a part that involves safety like brakes or steering, I stay away. A good example is knock sensors; they take hours to replace and the Dorman ones are known to fail so you’re soon back pulling the top of your engine apart. Other Dorman parts are great, like the 2-piece rear brake dust shields. The OEM ones are 1-piece and require pulling the damn axles to replace. Dorman makes 2-piece ones that take a few minutes to replace. Probably less quality, but they save time once the originals rust out.

I am on my 3rd doorman encoder motor the only reason I have have not bought an AC Delco is that they are easy to replace and it has always been under warranty when it went out. If it fails again and is out of warranty I will replace with AC Delco. I put Doorman control arms on my son's Jeep Liberty and have had no issues with them for about a year now we take both vehicles off-road frequently.

There was a fella on here who went through two brand new Dorman valve bodies for his transmission, they were junk out of the box, the TECHM.

What's wrong with stock AAM? You already have 1410 u-joints or 1350s? Both should handle the power anyways. It's the rpms that get them at that diameter and thickness, 5000 front and rear is the limit if steel. Not engine rpms, but shaft rpms.

Deff hit and miss. They make a PCV for the oem valve cover of my wife’s convertible bug. VW wants $5h in P&L to replace the entire valve cover on their 2.5L I5 20V motor. The Dorman parts takes 5 min tops to replace the PCV and a whopping $15 price point.
