AXIAL Racing SCX10 Pendulum Wheel Knuckle Weight + 21mm Hex Adapter by GPM SCX023A  [SCX023A]

Pendulum wheel weight for SCX10

This GPM aftermarket kit adds pendulum-style wheel weights and a 21mm hex adapter for AXIAL Racing SCX10 platforms. The assembly is an RC-scale accessory that concentrates additional mass at the wheel for improved downward force and more consistent ground contact during crawling and low-speed recovery.

Design details from the source describe stainless steel rolling beads that act as the variable mass element. The complete pendulum assembly is fitted to the outer face of the wheel knuckle (front and rear outer case) and is intended to keep weight low and centered at the wheel, helping the tyre bite into loose or low-lying terrain and return the chassis toward level.

Key mechanical notes provided include an adjustable bead stack of up to eight stainless beads, each 4g, yielding a per-wheel range of roughly 44–64 grams when fully populated. The kit uses stainless steel for corrosion resistance on muddy or wet tracks, and the 21mm hex adapter increases the hub width compared with the original specification to accommodate wider fitments.

Compatibility and fitment constraints must be observed: the product requires wheels with a 45mm inner diameter and wheel thread holes of 5mm, and it is listed for use with Axial SCX10 and SCX10 II platforms and select Gmade models. Installation is to the outer knuckle cases and may require wheel and hub checks to confirm clearance and thread alignment before use.

As a tuning item, the kit is aimed at scale crawlers where adding controlled unsprung mass at the wheel helps maintain contact in technical terrain; final bead count and wheel selection affect behavior so tune beads and verify wheel ID and thread before fitting.
