We took our legendary M6 axles and made them better by adding lightened outdrives. These now come standard in the M6 kits (TKR1951X, TKR6851X, TKR6852X). They are also available separately as a new option for current users. CNC machined from steel, lightened, then hardened for durability. These are for the front or rear end of your Slash/Stampede 44 as well as the rear of the Slash 2WD. Use the stock M3 screw pin for installation (TRA part number TRA6828X).
