GRK Lightweight Knuckle Stopper, 4mm thick [Shibata] R31S140

(GRK5RYH) This is a 4mm diameter aluminum knuckle stopper used in the GRK5-R HRP full kit . It was developed to further increase the maximum steering angle.

*Except for the reduced diameter of 4mm, the specifications are the same as the (R31S332) GRK Lightweight Knuckle Stopper.

*Because the safety margin has been reduced compared to conventional knuckle stoppers, depending on the specifications of the vehicle, there is a possibility that the joint may lock up due to reverse articulation during full counter-steering. In that case, please refrain from using it to protect the servo.
