GPM TRAXXAS TRX4 Pendulum Knuckle Axle Weight Set TRX4023XL - Chassis Option  [TRX4023XL]

Overview of pendulum wheel weights

This pendulum-style wheel knuckle axle weight set is made for TRAXXAS TRX4 Trail Crawler vehicles. Brass bodies combined with stainless steel rolling beads concentrate mass at the wheel, helping tyres maintain downward pressure during slow technical crawls and when negotiating uneven, low obstacles.

The kit is designed to mount at the wheel knuckle and, where applicable, on portal outer drives to boost both static and dynamic wheel-end weight. The beads can be removed for incremental mass adjustment, and the package includes the stainless fasteners and hex wideners needed for typical TRX4 wheel hex configurations.

Fitting advice: align the pendulum to the knuckle or portal flange according to your wheel and hex arrangement, install the correct hex widener to match your wheel hex, and secure the assembly with the supplied stainless screws and shafts. After installation, check for free rotation and ensure the added mass does not make contact at full suspension travel.

A practical tuning accessory for TRX4 crawlers where added wheel-end mass is required to improve low-speed traction and steadiness; use the removable beads and wideners to dial in handling preferences.
