Axles help get the power to the ground, so they're an integral part of your vehicle. Whether your ride is stock or modified, axles and axle components will usually eventually need to be replaced from excessive wear or damage. If you use your vehicle for any sort of aggressive driving or racing on-road or off, your axles and related parts may need to be upgraded with stronger components that can withstand the additional abuse that they will be put through.

Many import axle manufacturers rate their axles by how much horsepower they can handle and in numerical stages, such as Stage 1, Stage 2, etc. Most of these ratings aren't universal, so be sure to read specific product descriptions to see what each rating means. Some axle manufacturers tend to simply overbuild their axles, assuming that the end user needs an axle that performs above and beyond what the factory originally offered. When putting together a new axle assembly, be sure to use quality parts since all of your vehicle's power is transmitted through the axles.

Q: What are axles? Why buy them?
A: Axles are long metal shafts that physically connect your drive wheels to your differential allowing power to reach the ground. Every time you step on the gas your axles are put under a tremendous amount of torsional stress. Over time, especially if you like fast starts, this stress can cause the axles to weaken and eventually snap. If this occurs at the wrong moment it can be incredibly dangerous. Fortunately there are replacement axles available to take care of your weak old shafts. In addition to stock units there are also high-strength options available for people who have significantly upgraded their engines. If you are running a high-output motor do not risk driving on the stock axles shafts. Upgrade to stronger high-performance units and gain some peace of mind.
