RC enthusiasts, listen up! The Hot Racing Aluminum One-Way Center Differential is a game-changer for tight, technical track racing. Designed for Traxxas Slash 4X4, Stampede 4X4, Rally VXL, and Telluride 4X4 models (with a center gear diff setup), it lets your vehicle drive all four wheels forward under acceleration, but allows the front to \freewheel\ during braking, deceleration, and reversing. Why does that matter? It gives you way more steering control off-power, so you can \chuck\ the car into tight corners like a pro. Unlike a one-way front diff, this keeps your front differential action intact. You’ll need a spur gear made for a center gear differential (Hot Racing’s SSLF2* series works) – the stock slipper spur won’t fit. The kit includes the differential, a steel shaft, and three M3x5mm button head screws. It’s built tough from aluminum and comes with a 6x10mm one-way bearing. If you’re looking to sharpen handling and get that competitive edge, this upgrade is a solid pick.
