Overview
Restore tight, slop-free suspension and steering joints on your Arrma 1/7 or 1/8 BLX 6S vehicle with the Hot Racing Hardened #45 Steel Chrome Pivot Ball Set. CNC-machined from hardened #45 steel and finished with a smooth chrome plating, this 4-pack of 3x7.8x10.5mm pivot balls replaces the stock Arrma AR330202 pivot balls — a critical maintenance and consistency upgrade for any high-mile big-scale Arrma build.
Worn pivot balls are one of the most overlooked sources of vague steering, suspension slop, and inconsistent handling. Fresh hardened steel balls with chrome surfaces deliver tight, low-friction joints that translate directly to sharper, more predictable on-track behavior.
