This is the updated Tekno RC Steering Spindle Set. These spindles are the updated version of the TKR5541. They feature a larger outer bearing recess for use with TKRBB06135 bearings. The bearings increase durability in all conditions. These are also compatible with the original SCT410. The stock 10x15x4mm inner bearings are used.
Note: TKR5541 has been discontinued.
