Team Z Motorsports offers an Upper Torque Box Replacement Kit designed to replace your worn or damaged factory torque boxes on all 1979–2004 Mustangs. Built for strength, adjustability, and reliability, this version features multiple laser-cut pickup points, allowing you to fine-tune your upper control arm angle for better traction and launch control. Each adjustment hole is precisely spaced ¾ inch apart per row, providing clear, repeatable geometry changes for both street and strip applications.While our slotted torque box design offers micro-fine 0.125” incremental adjustments and remains the premium upgrade option, this multi-hole version delivers outstanding performance and value. When paired with Team Z’s Lower Torque Boxes and Fab 9 Housing, the system offers more adjustability than most 4-link setups on the market.Each kit is built from lightweight 4130 Chromoly steel, TIG welded, and assembled in-house for unmatched strength and quality. ARB tabs come pre-mounted for anti-roll bar use, and Grade 8 hardware is included. Optional upgrades include your choice of Team Z ARB systems. Proudly made in Detroit, Michigan — built by racers, for racers. Additional Notes Designed to work with conventional-length upper control arms Not compatible with Team Z relocated upper control arm kits.
