The MAXUM XST is a premium Smith machine trolley attachment engineered for smoother, safer, and more efficient barbell guidance. Compatible with all 3×3” racks with 1” holes and outside widths ranging from 47” to 49”, the XST delivers true plug-and-play versatility. A precision locking pin mechanism engages and disengages with a simple bar rotation, while the trolley rides directly on the uprights for stable, controlled movement. Integrated ISO handles open up powerful unilateral push/pull variations and grip options—perfect for building balanced strength.

Why the MAXUM XST Stands Out

• Locking pin system — rotate the bar to lock/unlock for fast, reliable operation.
• Compatible with all 3×3” racks with 1” holes and designed for outside widths between 47” and 49”.
• ISO handles enable unilateral presses, rows, and varied grips for balanced development.
• Trolley rides on the uprights for stable, controlled bar travel.
• Heavy-duty build stands up to intense, long-term use.

• Perform squats, presses, rows, and accessory work with guided bar stability.
