The HUDY 107623 Arm Reamer Replacement Tip suits 1/10 scale RC cars and provides a 3.0mm diameter with a 120mm length for accurate reaming of plastic suspension arm holes. It helps eliminate tight spots that cause binding during cornering.
Fine, hand-ground micro scurfies on the pin trim plastic cleanly so the arm bore is resized without stressing the part. That careful finish keeps pivots free and helps maintain predictable handling lap after lap.
