TRX4 Pendulum Wheel Knuckle Weight Set, Brass Body TRX4023C by GPM  [TRX4023C]

Pendulum wheel weights for improved low-speed traction

This 16 pcs pendulum wheel knuckle axle weight set is an RC-scale tuning accessory created to increase downward force for TRX4 crawling. The unit uses a brass body with an alloy lid and stainless steel rolling beads that concentrate mass low on the wheel to help tyres maintain contact over small voids and soft terrain.

The kit comes with a wider 9mm hex adapter for wheels that accept the larger hex, and includes screws, shims and washers for mounting to the outer knuckle case at both front and rear. Removable stainless beads let you adjust the pendulum mass on each wheel to suit driving style and terrain.

Materials were chosen for consistent mass and corrosion resistance: brass main weight, alloy lid, and stainless steel beads and fasteners for muddy or wet use. This is a tuning part for RC crawling and should be installed and tested on model vehicles only.

Tune bead count and shim spacing to fine-tune balance and low-speed grip on TRX4 trail crawlers.
