Model tuners will find the Factory Pro FP-M-AC3020BK 3mm x 2.0t black collars handy for repeatable spacing tasks. The 10 collars deliver uniform gaps and alignment that support reliable handling and component longevity.
These collars are versatile across chassis and suspension tasks. Fit them to control arm pivots, servo linkages, or bearing spacers to retain position and fine tune geometry. The black finish adds modest corrosion protection and a neat appearance.
The set matches many standard RC shafts and assemblies. With a 3mm internal diameter and 2.0t thickness, the collars provide a compact spacer solution that keeps parts stable without introducing excess bulk.
