For ARC A11: Short Lower Suspension Arms Upgrade O-ARCP12 by Factory Pro  [FP-O-ARCP12]

Aftermarket short lower arms built for ARC A11

The O-ARCP12 short lower suspension arm set from Factory Pro is supplied as an aftermarket replacement for the ARC A11 1/10 touring chassis. The parts are intended to be a direct-fit option that preserves mounting geometry while enabling small setup adjustments.

Fitting the arms uses the ARC A11’s original mounting points and fasteners. Typical installation involves removing the wheel and lower arm, then installing the O-ARCP12 units in the same orientation as the originals. Follow ARC A11 documentation or retailer instructions for torque and alignment guidance.

These short lower arms are primarily a tuning element to influence roll center and steering characteristics. Combine their use with damper and spring changes to dial in handling improvements; do not expect dramatic changes from one isolated part swap.

Select the Factory Pro O-ARCP12 set when replacing worn short lower arms on an ARC A11 or when experimenting with subtle geometry changes; always check fit before track use.
