PKT 50mm Axles

50mm axles by PKT. Commonly seen as OEM replacement axles, PKT's Chromoly/Mild Steel axle range for 50mm karting applications really deserve to stand alone as their own legitimate contender in the axle market. From substituting as well if not better for your OEM OTK axle, to giving you the performance where another axle might not, PKT has you covered for 50mm axle uses. Mild steel axles are denoted by the D line. All axles are cut for 2 and 4-cycle keyway and drive usages, as well as shifter kart usage. Various Wall thicknesses are available for the 50mm axle lineup: 1.6mm width: This is the thinnest-wall axle PKT makes, period. Use this axle if you are truly looking for the softest, most pliable axle out there. Often this axle would be excellent for low-grip tracks where the rear needs additional bite. 1.9mm width: A step up from the 1.6mm axle, the 1.9mm axle is still considered rather soft. For Tony Kart racers out there, this would be roughly the equivalent of a "Q" axle.
