TRAXXAS TRX4 Pendulum Wheel Knuckle Weight with 23mm Hex Adapter TRX4023XX by GPM  [TRX4023XX]

Brass pendulum wheel weight upgrade for TRX4

This pendulum wheel weight set is made for TRAXXAS TRX4 trail crawlers to add mass at the wheel end and lower the effective centre of gravity for better low-speed traction. The brass pendulum narrows toward the top and broadens at the base, running on a bearing with a Delrin collar so the weight stays oriented downward across a wide range of wheel articulation. The design helps the crawler regain contact on uneven ground and maintain grip at large crawl angles.

Fitment is aimed at the outer drive portal and requires wheels with a 45mm inner bore and a 5mm threaded hole. The included 23mm hex adapter increases the offset versus the stock hex to position the pendulum correctly. Each pendulum plus hex assembly weighs 133 grams and the 12 pcs set is intended as an aftermarket wheel hub upgrade for RC crawlers only.

Use these brass pendulum weights when you need extra wheel-end mass to stabilise slow-speed crawling and improve grip on steep, rough sections; check wheel bore and thread compatibility before installation.
