Overview
Get the most out of your Hot Racing +4mm Steel Drive Stub Axle Set (HRASXTF39W04) with the matching Hot Racing Brass Axle Weights. CNC-machined from solid brass billet, this 4-pack adds 5 grams of unsprung weight at each wheel position — a total of 20 grams of low-CG mass that further improves stability, climbing, and overall crawler composure on the Axial SCX24.
Adding weight at the wheel/axle level is one of the most effective tuning moves you can make on a scale crawler. Combined with the +4mm wide-track stance, these brass weights take the SCX24's technical capability to the next level.
