The Tamiya 15417 JR 72mm Reinforced Shaft gives Mini 4WD tuners a tougher axle option without changing chassis geometry. Built from 60C steel, these shafts are aimed at enhancing part life under regular racing conditions.
Made to fit Super X, Super XX and R/C 4WD TR-1 chassis platforms, these shafts drop in as a straightforward upgrade. The black nickel plating adds surface protection and a clean finish that holds up during repeated runs.
Using the Tamiya 15417 shafts helps keep power delivery smooth and predictable, aiding stability through corners and improving throttle response on longer straights. They are a solid choice for tuning balance between speed and control.
