XRAY RX8 Rear Lower Inner Pivot Pin for Upgrades - Arrowmax AM-RX8-357210  [AM-RX8-357210]

RX8 rear lower inner pivot shaft replacement

This Arrowmax replacement pivot pin is an RC-scale rear lower inner shaft made for the XRAY RX8 chassis, built from spring steel with a titanium nitride finish to lower surface friction and resist wear. It sits at the suspension inner pivot where smooth, repeatable articulation matters for consistent handling.

The part serves as a direct spare or aftermarket upgrade for RX8 owners who prefer a low-friction pivot without modifying suspension geometry. Installation reuses the chassis retainers and lower arm interfaces, so basic removal and a fit check are all that are required before running. After fitting, confirm the pin seats correctly and that there is minimal lateral play.

Tuning note: swapping worn pins for a titanium nitride coated spring steel unit reduces contact wear at the inner pivot, helping preserve trim and steering feel across multiple runs while simplifying routine suspension maintenance.
