Swaybar Arms

Currie Antirock sway bar arms are measured by overall length. A longer arm puts more leverage on the sway bar, reducing its anti-sway effect. A shorter arm increases the anti-sway effect, but must still be long enough to follow the suspension travel. Thus, the trick is to choose sway-bar arms that are neither too short for the suspension travel nor too long for the needed degree of anti-sway. Eighteen-inch aluminum arms got the nod on the 4Runner. On the passenger’s side, the body had to be notched above the arm for bump-travel clearance.
