This 2-inch aluminum servo arm fits JR and SPM servos, delivering a precise, slop-free linkage for reliable RC control.

Constructed from durable aluminum and finished in black powder coat, it offers lasting durability and a clean, professional look. The arm features an accurate spline attachment with Spline-Loc technology to ensure a secure connection to the servo, while recessed screws lock in place at both the spline and the servo mounting screw for added resistance to loosening. The result is precise actuation and dependable performance in models that demand consistent, responsive control.
