The Ford Racing harmonic damper for 302/351 applications controls crank twisting across the rev range to reduce valve-train vibration and minimize timing scatter. Available in iron and steel constructions, this damper meets SFI 18-1 approval and is balanced to specified ounce-inertia values, offering a durable option for engines that need improved crank damping and more consistent timing behavior.
