The Factory Pro 3mm Red Collar Set is a simple way to make precise spacing adjustments on your model. Each thickness is supplied in five pieces so you can experiment until the handling feels right.
Use these collars to tweak camber links, axle spacing or gearbox alignment. The bright red colour helps you identify sizes quickly when changing setups between runs.
These collars suit many standard 3mm shaft fittings and are intended for hobbyist use where repeatable spacing is helpful during setup iterations.
