This machined upper Y-arm is made to fit the Axial SCX-10 Honcho chassis and is supplied in black. It replaces the factory plastic arm with an alloy component intended to stabilise suspension geometry and deliver a secure mounting point for the upper link.
Fitment uses the stock SCX-10 Honcho upper suspension mounts and the original hardware. Simple fit checks include pivot alignment, proper ball stud or pin seating, and confirming there is no binding through the full travel. Standard hex drivers and common hand tools are normally all that are needed.
The arm is a chassis-level upgrade that preserves the suspension layout while improving the solidity of the mounting reference for camber, caster and roll centre adjustments. Install it to aid repeatable tuning when preparing for trail or scale crawl outings.
