A 39-tooth front direct coupling set for the XV-02 and TT-02. A direct coupler, also called a spool, replaces the oil-filled gear differential in the XV-02 base kit. With no differential action at the front, the wheels turn at the same rate, which gives steadier braking and more forward drive on low-grip surfaces. The tradeoff is less rotation through corners. Choose it based on conditions and track layout. Included: aluminum front direct coupling x1; direct cups (steel) x2; direct coupling ring gear (39T) x1; bevel pinion gear (for 39T gear) x1; 2x9.8mm stainless steel shafts x2; axle rings x2; 2.6x6mm cap screws x4. Fits: Tamiya TT-02, TT-02 Type S D, TT-02 Type S, TT-02B 4WD Buggy, TT-02D, XV-02
