This upper A arm mount is made for Yokomo R12 and GT series RC models. Constructed from graphite resin, the item is stiffer than the original component, helping to refine steering trace and support crisper turn-in without modifying suspension geometry.
Fitment and role: the part replaces the front suspension's stock upper arm locating point and integrates with the existing suspension links and uprights on compatible R12 and GT chassis. As a targeted chassis tune, it boosts local rigidity around the upper arm joint so steering inputs are transferred with reduced flex, improving transient steering consistency.
Installation notes: designed to substitute the original upper arm mount. You will need to partially disassemble the front suspension to fit the part; common hex drivers for your chassis will do the job. After fitting, re-check alignment and steering freeplay to confirm the expected steering changes.
