The GPM SCX023 pendulum wheel knuckle adapter is engineered to add controlled mass to each wheel on AXIAL SCX10 platforms, improving tyre contact patch and stability during slow-speed rock crawling. The adapter assembly incorporates a bearing and a Delrin collar to manage the added weight while maintaining smooth rotation, helping the vehicle achieve greater crawling articulation without compromising control. This part is suitable for hobbyists seeking a durable upgrade to refine suspension balance and low-speed traction.
