When you are looking at aftermarket axles there are a couple of things that you need to consider before making your final selection. The difference between an OEM and Aftermarket axle is the material that the axle is made out of. It’s important to make sure that the vehicle you will be driving has a smooth ride. OEMs usually use forged aluminum spindle-and-axle housings, which are stronger than aftermarket housings. Aftermarket cv axles usually use chrome-plated, lightweight materials that are more durable, but they are usually much heavier than an OEM axle.
An Aftermarket axle is usually described as “fiberglass reinforced polycarbonate” (FRP). There is a lot of technical jargon involved in the entire process, but basically, there are some common characteristics you should look for. If the housing is stamped, there is a more substantial build and better weight distribution. Also, the housing is designed to bolt on easily and to not require a full coating of urethane to keep its intended strength. Oftentimes, an aftermarket axel will have the same or similar features as an OEM axle; for example, an adjustable angle lock, oil fill port, locking tail pins, etc…
If you are looking to replace or build an engine for your truck, marine application, or snowmobile, the most common aftermarket parts include rebuildable axels and cams. Although the majority of these parts are available through your dealer, you may also be able to find some rebuildable camshafts online or locally. Many of these types of parts are made of high quality metals, which are extremely strong and very durable. Aftermarket axles are not the only option for customizing your vehicle; they can also be used for commercial applications like tractors, excavators, bulldozers, forklifts, etc… To see if you would be able to use a rebuilder axle in your situation, contact an online mechanic specializing in aftermarket parts or a local repair shop.
