The DERBYWORX Pro Axle Pliers from Maximum-Velocity are the ULTIMATE way to safely handle the axles and wheels of your Hi-Performance Derby Racer. The specially designed groove in the pliers tip safely grips around the axle head not only allowing safe removal of axles and wheels, but they are truly the BEST tool available for making those small axle adjustments when performing a wheel alignment. We recommend the Pro Axle Pliers when setting up your cars with our Rail Rider® alignment technique and for careful handling of light weight / high performance Derby Wheels.
