The Arrowmax AM-MAX2-018 upper arm mount is crafted from brass as a direct replacement for the Yokomo B-MAX2 plastic component. It adds mass where it matters and beefs up the arm pivot for greater resistance to wear and flex. The component weighs 26 grams and is commonly used to refine front-end stability during competitive runs.
Adding brass increases rotational inertia at the arm, helping the car resist sudden load transfers and keeping the tyres more settled on corner entry. The Arrowmax unit brings a straightforward way to tune the Yokomo B-MAX2 without altering fundamental geometry.
