Upgrade for ARC A11 Rear Short Lower Arm - O-ARCP12R by Factory Pro  [FP-O-ARCP12R]

Short lower arm for rear tuning

The Factory Pro O-ARCP12R short rear lower suspension arm is an aftermarket component crafted for the ARC A11 chassis to provide a shorter rear lower arm alternative.

It is supplied as one piece, designed to be a drop-in change at the rear lower suspension point to restore geometry or to explore setup variations with a shorter arm. Compatibility is limited to ARC A11 models; confirm your chassis code before fitting. Installation requires standard disassembly of the rear lower arm retention pins and linkage hardware, swapping the arm, and verifying alignment and roll-center differences. From a tuning perspective, the shorter arm influences roll behavior and can shift rear traction and steering balance; approach changes in small increments.

Key notes:

• Includes 1 pcs, short variant of rear lower arm.
• Made for ARC A11 chassis compatibility only.
• Designed for RC car maintenance and tuning purposes.
