Are OEM Transfer Cases Better Than Aftermarket?
When it’s time to replace your transfer case, you face two options:
- Buy and install an OEM replacement transfer case
- Buy and install a rebuilt or used aftermarket transfer case
Are you trying to decide between OEM and aftermarket transfer cases? This comparison guide is what you need.
The best way to reach an educated decision is to evaluate the most important factors of a transfer case. We’re going to do just that. Here are the 3 most important factors to consider while shopping for a transfer case.
1. Longevity
If you're buying an aftermarket transfer case, you will either get a rebuilt unit or just a used transfer case. There are downsides to each:
Used Transfer Case - You have no idea how the prior owner took care of the transfer case. Was the gear oil changed at regular intervals? Did the owner drive the vehicle hard off-road? Did they leave the vehicle in 4wd on dry pavement? How many miles are on it? Used transfer cases are cheap, but they come with unknowns.
Rebuilt Transfer Case - A typical rebuilt transfer case has the bearings and seals replaced, and gears are replaced if they look worn. There are two risks in this case. One is the quality of the parts used, and the other is the ability of the technician doing the rebuild. Transfer cases are complex, and have to be rebuilt to very tight tolerances in order to have a long life. Either poor part quality or a poor assembly job could result in a transfer case that doesn't last very long.
2. Quality

Have you ever wondered why aftermarket transfer cases are usually so cheap? It’s because many rebuilders use low quality components. Rebuilding a transfer case is labor intensive. It takes a skilled technician several hours to do the job. As it takes so much time, the temptation is strong to use non-OE components to save some money.
An aftermarket transfer case with low quality components may cause these problems:
- Difficulty engaging 4Hi or 4Lo
- Transfer case popping out of 4Hi or 4Lo
- Short lifespan
- Reliable performance
- Longevity
- Smooth shifting
3. Warranty
If you buy an aftermarket transfer case, and it fails early, you’d have a hard time getting it replaced for free. Aftermarket manufacturers rarely warranty their parts. That’s another reason why aftermarket transfer cases are usually so cheap. What if you actually find an aftermarket transfer case that comes with a warranty? Chances are the warranty policy is written in the manufacturer’s favor.
GM offers a comprehensive parts warranty policy for transfer cases. It’s good for 3 years or 100,000 miles, whichever occurs first. So if you get an OEM transfer case, you’ll have the peace of mind that it’s protected under warranty.
In A Nutshell
There are many different aftermarket transfer cases on the market. Some of them are well built with quality materials. Yet, no aftermarket transfer case compares to the real thing. If you want a transfer case that fits right the first time and offers reliable performance, OEM is the way to go. An OEM transfer case will always fit your vehicle and perform well.
OEM Transfer Cases Aren’t Always Expensive
A common misconception is that OEM parts always break the bank. It’s no wonder, considering how:
- Most GM owners shop for OEM replacement parts at dealerships.
- Dealerships tend to mark up their prices by about 30%.
