Kyosho W0145GM Aluminum Collar 3x7x1mm (6)

Kyosho W0145GM is a six-pack of genuine aluminum collars measuring 3mm inner diameter, 7mm outer diameter, and 1mm thick. These anodized aluminum spacers are machined to precise thickness, making them the clean way to fine-tune spacing anywhere a 3mm screw or stud passes through the chassis. At 1mm thick, this size is ideal for subtle adjustments: shimming ball studs to tweak camber link angle, spacing servo horns, setting small gaps at suspension mounts, or dressing screw heads with a finished look.

Kyosho lists these as general-purpose hardware, and they see common use across the Ultima RB5, RB6, and SC along with the Lazer ZX-5, while working equally well on any vehicle that uses metric 3mm hardware. Aluminum resists crushing far better than plastic spacers, so once you set a measurement it stays set run after run. Package includes six collars in the 3x7x1mm size, an easy add to keep your hardware drawer complete.
