Yokomo YOKD123 - Aluminum Lower Caster Block Set 10 degree  [YOKD123]

The Yokomo YOKD123 aluminum lower caster block set provides a fixed 10° lower caster option designed for RC-scale suspension tuning. Made from machined aluminum, the parts replace standard plastic blocks to offer a firmer mounting point for the lower suspension arm and steering knuckle interface. This set is intended as a tuning component to alter caster and steering response rather than a generic repair item.

In practice, installing a denser material lower caster block affects roll center and steering return characteristics. Use these blocks as part of a measured setup change when you need crisper steering feedback or a slightly increased self-centering effect at the front end. They are best paired with a compatible 1/10 touring or pan car chassis where lower caster blocks match the hub geometry.

Installation requires standard suspension disassembly to access the lower arm pivot and knuckle; confirm hole alignment and fastener lengths against your chassis before final tightening. Check steering travel and binding after fitment and re-evaluate toe and camber settings as small caster changes influence overall wheel alignment.
