ARC A11 Lower Arm Replacement Set O-ARCP11 for ARC A11 by Factory Pro  [FP-O-ARCP11]

Overview: lower suspension arms

The Factory Pro O-ARCP11 lower suspension arms are supplied as an aftermarket replacement for the ARC A11 touring chassis. They are intended to recover correct geometry after impact or wear and to support precise suspension setup work.

Compatibility and fitment are central when choosing lower arms. This set is built for the ARC A11 platform and should align with stock mounting points and track width. Prior to fitting, check the O-ARCP11 part number against your current components and confirm ball stud and hinge-pin locations match.

Replacing the arms is straightforward for those comfortable with RC servicing: remove wheels, unbolt hub carriers and the damaged arms, move over any bearings or hardware you will reuse, and mount the new arms in the same orientation. After installation, confirm unobstructed suspension travel and check that hinge pins and inboard mounts are free of binding. Minor trimming or hinge-pin repositioning may be needed for custom setups.

In setup terms, lower arms affect roll center, camber behavior, and how the car responds to inputs. Swapping worn arms restores consistent geometry and predictable handling. Once installed, recheck alignment and toe settings, then perform a short run to verify chassis balance and handling before making further tuning changes.

This lower arm set is an RC-scale replacement intended to preserve ARC A11 suspension geometry; confirm O-ARCP11 fitment before ordering to ensure correct installation and tuning continuity.
