This 7075 aluminum steering servo arm is intended as an aftermarket replacement for the Axial 1/6 SCX6 Jeep and is sold under model JR-SCX607-BK. It reduces flex compared with stock plastic arms and is aimed at hobbyists upgrading components for better steering control.
Installation is straightforward: align the spline interface on the servo, fit the arm in the correct orientation, and secure with the existing mounting screw. Confirm fit and included items with the seller before final installation.
