Control Arm Inner Adjuster Bolt

The Mazda Miata shaft kit, part number NA80-28-66ZD, is a genuine OEM component engineered as a direct replacement for factory suspension hardware. It functions as a lower control arm adjustment bolt, providing the necessary precision for suspension alignment and control arm positioning. This kit replaces previous part numbers na802866zb and na802866zc. Designed specifically for 1990-1997 and 1999-2005 Mazda Miata models, this component ensures factory-spec fitment and durability. As a genuine Mazda part, it is backed by the manufacturer's limited warranty. Due to the critical nature of suspension geometry, VIN-based verification is recommended prior to installation to confirm exact compatibility with your specific vehicle configuration.
