Upgrade the Traxxas TRX4 Trail Crawler with GPM aluminum pendulum wheel knuckle axle weights to improve footing on slopes and in soft ground. The extra mass helps the tyres bite into the surface for steadier climbs.
The design uses stainless steel rolling beads to add 42 grams per wheel, lowering the centre of mass and improving adhesion. Stainless elements resist corrosion, so the weights perform well after wet or muddy runs.
The pendulum arrangement applies a steady downward force as wheels articulate, aiding low-speed crawling. The included 6mm hex adapter is 1mm wider than standard to increase wheel stability and control.
