| | OE CV axles typically won´t fail because the driveshaft goes first. Once the driveshaft is upgraded, the CV´s become the next weak link and typically break at the axles´ transition on the shaft. A broken CV axle can cause thousands of dollars in damage before getting the car stopped. Don´t risk it, our heavy duty CV axles use custom billet CV joints and 300M axle material. The axle itself is 1-3/8" diameter compared to the OE 1-1/16" and is capable of handling 800+ RWHP | |
