Short Lower Suspension Arms compatible with ARC A11 - O-ARCP12 by Factory Pro  [FP-O-ARCP12]

Replacement lower arms for ARC A11 chassis

The Factory Pro O-ARCP12 short lower suspension arms are offered as an aftermarket replacement for the ARC A11 1/10 touring car chassis. These arms are designed to fit the ARC A11 mounting pattern and to maintain the original suspension geometry while allowing measured tuning changes.

Installation is straightforward when working within the ARC A11’s existing mounts and fasteners. Remove the affected lower arm assemblies, transfer any needed hardware, and secure the O-ARCP12 arms in place. Consult the ARC A11 service information for correct orientation and torque values.

These short arms are intended to provide fine adjustments to roll center and front/rear steering feel, and they perform best when used as part of a coordinated setup including damper tuning and spring selection. They are a tuning tool rather than a wholesale chassis modification.

Use the Factory Pro O-ARCP12 to replace worn short lower arms on an ARC A11 or to trial small geometry changes; always confirm fitment before competitive use.
