AXIAL Racing SCX10 Brass Pendulum Wheel Knuckle Axle Weight with 21mm Hex Adapter by GPM SCX023X  [SCX023X]

Pendulum wheel axle weight for SCX10 crawlers

This is an RC-scale pendulum wheel axle weight designed to add low‑mounted mass at each wheel to improve traction and stability during slow rock crawling. The assembly uses a brass pendulum shape that is narrower at the top and wider at the bottom to keep mass downward, and a bearing with a Delrin collar to allow free pendulum motion across different steering and suspension angles.

Key fit and functional notes: the pendulum plus 21mm hex assembly is intended for installation on the outer drive portal so the chassis center of gravity remains low, the 21mm widened hex increases wheel offset versus the original by 16mm, and a single pendulum plus hex measures 136 grams. This part requires wheels with an inner diameter of 45mm and a wheel thread hole of 5mm to mount correctly.

The product package includes the hardware needed for installation: 21mm hex adapter (2 pcs), stainless steel pin 2x10 (2 pcs), 5mm spring steel shims (2 pcs), 5mm metal washers (2 pcs), and 19mm stainless steel hex socket screws (2 pcs), and a central bearing with Delrin collar.

Use this GPM pendulum weight when you need lower CG and extra wheel bite on slow, steep, or uneven terrain; confirm wheel inner diameter and thread size before purchase.
