This aftermarket kit fits pendulum-style wheel weights plus a 21mm hex adapter designed for Axial SCX10 platforms. The assembly concentrates extra mass at the wheel to increase downward force and help maintain contact during slow, technical crawling and recovery moves.
The variable-mass element uses stainless steel rolling beads that run freely inside the pendulum housing. The complete unit mounts to the outer face of the wheel knuckle (front and rear outer case), keeping added weight low and close to the wheel to encourage tyre bite into loose surfaces and help the chassis settle back toward level.
Key mechanical data includes an adjustable bead stack of up to eight stainless beads at 4g each, providing roughly 44 to 64 grams per wheel when fully populated. The hardware is stainless for better corrosion resistance on wet or muddy runs, and the included 21mm hex adapter expands hub width to suit wider wheel fitments.
Observe compatibility and fitment limits: the kit requires wheels with a 45mm inner diameter and wheel thread holes of 5mm. It is listed for use with Axial SCX10 and SCX10 II platforms and select Gmade models. Installation mounts to the outer knuckle cases and may need wheel and hub clearance checks before final fitting.
As a tuning accessory, the kit is aimed at scale crawlers where controlled unsprung mass at the wheel helps retain contact on technical terrain; experiment with bead count and confirm wheel ID and thread alignment before use.
