Description
Geometry is the feature you can't bolt on.
Every bend in a cable costs you — friction on every rep, wear over every year. Two things set that cost: how small the pulley is, and how far the cable has to wrap around it.
We engineered the Mutant Arms head to minimize both. The 70mm 1:1 pulley sits above the cable line, so the cable barely deflects to pass over it — a glancing bend, not a hairpin. Designs that hang their 1:1 pulley below the cable force a full 180° reversal at double tension, on every rep, at the single highest-stress point in the system.
Bigger pulleys. Shallower bends. Both by design. That's why the pull feels smooth on day one — and why it still feels smooth in year five.
Docked by design
The 1:1 pulley lives in a dedicated dock on the head — the position that gives it its shallow wrap angle. Switching modes takes seconds: clip to the bracket for 1:1, clip to the cable end for 2:1. The pulley returns to its seat, the geometry resets, and every rep starts from exactly the same place. One system, patent-pending, engineered as a whole.
The head that follows your pull
Cable geometry only works if the head stays pointed at your hands. Every articulating arm head is bottom-heavy — pull horizontally or overhead, and it wants to rotate away from the line of pull. When that happens, the cable stops riding the pulley grooves and starts grinding the flanges. More friction. Faster wear. A pull that suddenly feels rough.
The T-shaped magnetic counterweight fixes what other designs ignore. Snap it on for horizontal and overhead work and the head stays balanced, aligned with cable travel through the whole rep. Pull it off when you don't need it. No tools. No threads. No compromise in the geometry you paid for.
A dock that guides itself home
The 1:1 pulley seats into an engineering-grade ABS housing shaped to do three jobs. Its geometry self-locates the pulley — it finds its seat by feel, every time, no fiddling mid-workout. The ABS absorbs the docking contact, so the steel head stays unmarked through thousands of mode switches. And it keeps weight off the end of the arm, where every gram matters each time you reposition.
We could have machined it from metal. It would have been heavier, harder on the hardware, and worse at the job. We chose better instead of heavier.
DETAILS
The patent-pending upgrade that turns your MAXUM rack into a full-motion training system.
Your Maxum rack is already a powerhouse. The Mutant Arms make it unstoppable. Engineered as a direct upgrade for the X Series and SX2, they bring full horizontal and vertical articulation to your cable system — plus a dedicated 1:1 attachment point that delivers true, pound-for-pound resistance.
Articulate in every direction
Horizontal and vertical movement lets you position the pulleys exactly where each exercise demands. Go wide for chest flys and cable crossovers, bring the arms together for lat pulldowns and seated rows, or angle them up and down for presses, pulls, and everything in between.
True 1:1 cable ratio
The additional attachment point delivers a genuine 1:1 ratio, so the weight you load is the weight you feel.
Balanced articulation when you need it
The included T-shaped counterweight offsets the rotating end of the arm for horizontal and bottom-up cable pulls — think seated rows, cable curls, and upright pulls — where gravity won’t keep pulleys in line on its own. For top-down movements, it lifts off in seconds, so you only carry the counterweight when it’s earning its keep.
Unlock more exercises
With a wider range of cable angles than any arm we’ve built before, the Mutant Arms open up dozens of new movement patterns — from overhead presses and low rows to rotational and rehab work your old arms couldn’t touch.
Everything you need, in the box
Each upgrade ships with a complete matched cable set, so you’re not scavenging parts from your current setup. Install, re-rig, and train.
Built to Maxum standards
Heavy-duty steel construction and precision pulleys, finished to match the rest of your rack seamlessly.
