The 3Racing SAK-A573A Aluminum Spur Gear Mount is engineered to deliver stable spur alignment on the Sakura Advance 21 chassis. Its aluminium construction reduces deformation under load, helping maintain accurate gear mesh through aggressive acceleration and braking.
Aluminium offers predictable stiffness and repeatable mounting points, which are important when tuning gear engagement for racing. The mount reduces drivetrain flex that can otherwise alter mesh under cornering loads.
Designed to match the Sakura Advance 21 mounting pattern, the part ensures consistent positioning of the spur gear relative to the pinion. This consistency simplifies setup adjustments and supports lap-to-lap repeatability.
