GPM Axial SCX10 Pendulum Wheel Knuckle Axle Weight with 31mm Hex Adapter - SCX023B Pack  [SCX023B]

Pendulum axle weight for SCX10 crawlers

This pendulum wheel knuckle is an RC axle-end weight designed to improve low-speed traction on AXIAL SCX10 platforms by shifting unsprung mass down and outboard. The weight profile is tapered so the mass stays low as the chassis tilts, helping the tyre hold contact on steep or uneven sections.

The assembly uses a central bearing with a Delrin collar to let the pendulum swing freely and is supplied with a 31mm hex adapter to accept wider wheels. Manufacturer fit notes: each pendulum weighs 82 grams, the 31mm hex is 25mm wider than the original hex, compatible wheels need a 45mm inner diameter, and the wheel must have a 5mm threaded hole to accept the supplied fasteners.

Fit these weights when tuning for crawling stability and grip rather than speed. Adjust wheel offset, tyre selection, and suspension tuning together with the pendulum weights to reach the best balance for technical lines and boulder fields.

For axle-end mass tuning on AXIAL SCX10 crawlers this pendulum kit shifts weight low and outboard to help traction on steep obstacles; confirm the 45mm inner wheel diameter and the presence of a 5mm threaded hole before fitting.
