The SwitchBlade sway bar allows users the ability to fine-tune the amount of sway control the unit can provide without the need for special tools or complication. Simply grab hold of the arm, pull back slightly, and rotate it until the desired amount of resistance is achieved. Each blade arm has three positions governed by machined grooves inside the corresponding indexing head. As the swing arm is rotated and released, it settles into one of the three available locking positions—vertical, horizontal, or diagonal. The variable resistance comes from the individual arms orientation and its ability to flex like a leaf spring.
