This GPM TJ010-5MM hub set is a CNC-machined 7075-T6 alloy upgrade designed to replace stock wheel hubs on compatible Traxxas models to widen the track by 5mm. The parts act as 17mm hex adapters that mount between the knuckle arm and the wheel, increasing contact area with 17mm splined wheels to reduce slippage and help prevent hex rounding when running larger tires or heavier loads.
The hubs are intended for 2S use only and are compatible with both 17mm splined wheels and traditional 17mm hex wheels, giving flexibility for different wheel and tire combinations. They are also designed to work with Maxx-duty axles used in #9080-series Extreme HD upgrade kits and fit Maxx-duty drivshafts with 6 mm axles.
Installation is a direct replacement for the stock hubs on supported Traxxas chassis, using the provided 17mm hex interface; basic hand tools are sufficient for fitment. In tuning terms the 5mm widen provides a small but effective change to lateral stability and cornering balance, useful when fitting wider tires or adjusting handling for different surfaces.

If your setup uses wider tires or you are fitting an Extreme HD driveline, these hubs provide a durable 7075 alloy option to widen track and maintain a secure 17mm interface, while keeping installation straightforward for routine chassis tuning.
