The Eaton Detroit Truetrac (MPN 912A569) is a premier helical-gear style limited-slip differential designed to maximize wheel traction and improve handling. Unlike traditional plate-style LSDs, the Truetrac utilizes a gear-based timing system that provides smooth, automatic torque bias without the need for wearable clutch packs or special friction modifiers. This maintenance-free design ensures quiet operation in both forward and reverse, making it an ideal traction solution for daily drivers and weekend trail enthusiasts alike.
