THE NEW STANDARD IN AXLE FASTENERS HOW DOES ZIP-TORQWORK? The STEMCO Zip-Torq axle fastener is the latest innovation from STEMCO. Zip-Torq is a unitized spindle nut that uses a patented self-locking ratchet system to secure the wheel end and prevent back off. Zip-Torq consistently delivers accurate endplay between .001"–.005" using the STEMCO 2-1-1 method. ZIP-TORQ FEATURES Superior Wear Resistance Bearing contact surface is induction hardened. No washers required. Improved Threads Zip-Torq engages twice as many threads to firmly seat and lock wheel bearings securely. Infinite Locking Positions Nut and spring steel keeper mate and lock at any point on the axle spindle in .001” axial increments. Highly Visible Adjustment Marks Give mechanics precise control of nut backoff amount during installation. EASY & FAST INSTALL Installation time of the Zip-Torq is the same or faster than Pro-Torq ® , reducing time in the shop.
