This kit provides an RC-scale pendulum wheel knuckle axle weight solution made for TRAXXAS TRX4 Trail Crawler setups. Brass weight bodies with removable stainless steel rolling beads add concentrated mass close to each wheel to help tyres keep downward force during slow, technical crawling and when crossing rutted or soft surfaces.
The components mount to the wheel knuckle and, where applicable, the portal outer drive to raise both static and dynamic wheel-end weight. The rolling beads can be taken out to fine tune pendulum mass per wheel, and the included hardware list covers the stainless fasteners and hex wideners required for common TRX4 hex sizes.
Installation tips: position the pendulum assembly on the knuckle or portal flange to suit your wheel and hex arrangement, fit the supplied hex wideners to match your wheel hex, and secure using the provided stainless screws and shaft parts. After fitting, verify free wheel rotation and confirm the added mass clears suspension components and bodywork through full articulation.
A hardware-level tuning option for TRX4 crawlers where extra wheel-end mass is needed to improve low-speed traction and stability on technical lines; use the removable beads and wideners to match wheel setup and handling goals.
