The RetroArms CNC Anti-Rotation Bushings (3mm) are designed to provide maximum durability and gear stability in high-performance AEG builds. Precision CNC-machined from solid steel, these bushings feature an anti-rotation design that prevents unwanted movement inside the gearbox shell — ensuring consistent gear alignment and long-term reliability under heavy stress or high-RPS setups.
Ideal for techs who want rock-solid support for their gear axles, especially in setups with high-speed motors or high-torque spring loads.
