A TorqueArm is a longitudinal rear suspension link that controls axle wind-up under acceleration and braking by transferring torque reaction loads through a single rigid arm extending forward from the rear axle to a chassis mount. Griggs Racing engineered the TorqueArm system for Mustang applications to eliminate the geometry compromises of traditional four-link and three-link rear suspensions, providing predictable launch behavior, reduced wheel hop, and consistent rear-axle location under all driving conditions.
