This pendulum wheel knuckle is an axle-end weight solution for Axial SCX10 chassis that helps lower the vehicle centre of gravity and increase tyre contact when negotiating high-tilt obstacles. The weight geometry is narrow at the pivot and wider at the bottom so the mass stays down as the crawler leans.
The unit rotates on a central bearing with a Delrin collar to allow smooth swing, and it ships with a 31mm hex adapter for broader wheel fitment. Fit data from the maker: each pendulum is 82 grams, the 31mm hex measures 25mm wider than the stock hex, wheels must have a 45mm inner diameter, and wheels need a 5mm threaded hole for the supplied screws.
Install when the goal is improved low-speed traction and balance; pair the pendulums with suitable tyres, offsets and suspension setup to tune the crawler for the local rocks and trails.
As an axle-end tuning option for Axial SCX10 rigs, this pendulum kit shifts weight low and outboard to aid traction on steep or low-profile obstacles; always check wheel internal diameter and thread compatibility before fitting.
