The Evolution Motorsport Axle Kit is a direct replacement engineered to withstand the most extreme conditions without failure. The OEM axles have been known to break during drag racing or hard street launches on cars producing over 600 HP. Additionally, road racing cars such as the GT3R are quipped with improved axles from the factory due to their extreme environments. The Evolution Motorsport Axle Kit is virtually indestructible, will prevent failures and are guaranteed against breakage even under the most extreme conditions. Evolution Motorsports has field tested these axles and have tried to break them with over 900 HP launches with drag slicks and on road race cars making 800+ HP to no avail.
