Factory Pro O-ARCP12F ARC A11 Short Front Lower Arm  [FP-O-ARCP12F]

Product details and fit notes

This Factory Pro aftermarket lower suspension arm is an RC-scale replacement made for the ARC A11 front lower arm location and sold as one piece. The short-profile form factor is intended for hobbyists adjusting geometry to refine handling on 1/10 touring RC cars.

Installation on ARC A11 chassis is straightforward because the arm aligns with factory mounting points and normally does not require chassis modification. Verify pivot freedom and correct ball joint orientation during fitting, ensure full suspension travel is free of binding, and keep the original hardware unless an alternate mounting method is needed.

Used for tuning, the shorter lower arm produces subtle shifts in front geometry that affect roll center and initial turn-in. Introduce it incrementally: swap one side first or perform controlled tests to measure its effect along with spring and damper changes.
