This Arrowmax aluminium front lower 1-piece suspension holder is intended as an RC replacement for the XRAY T4'20 front assembly. Crafted from machined aluminium, it offers a single solid mounting face for the front lower arm used in front-FF 1/10 touring car configurations. The write-up concentrates on compatibility and installation details rather than claiming performance gains.
Mounting follows the T4'20 front points and uses the chassis standard hardware holes. Installation generally requires common hand tools such as hex drivers, and it is advised to reuse original screws and washers or obtain identical replacements. The component sets a stable geometry reference for the lower arm and is compatible with matching stock or aftermarket steering and arm components designed for XRAY T4'20 geometry.
Setup effect: switching to this aluminium one-piece lower mount increases the stiffness and consistency of the lower-arm attachment compared with composite parts, aiding precise adjustments and repeatable testing during setup work. Consider it a chassis-level tuning item for meticulous suspension work.
If you are tuning a T4'20 or replacing a degraded front lower mount, this aluminium one-piece holder gives a consistent mounting datum; confirm part fit and whether fixings are supplied before purchase.
