VTS Rack Attachment

The VTS (Versa Trolley System) is Bulletproof Fitness Equipment’s rack-mounted trolley that converts a squat rack’s uprights into a Smith-machine-and-cable-station in place of a dedicated standalone unit. Each trolley rides on eight UHMW rollers with high-grade bearings on all four sides of the upright, so it tracks smoothly under any load configuration and works whether you clamp on a barbell for connected Smith-style pressing or run each side independently with ISO handles for unilateral work. A proprietary hex-port system accepts a growing lineup of Bulletproof accessories — single handles, weight horns, foot plates, shoulder pads — so the same core unit can be reconfigured for pressing, pulling, leg press, and hack squat movements. It fits 3x3, 2x3, and 2x2 uprights on either 1” or 5/8” hole spacing, and accommodates most 7’ Olympic barbells (28-30mm standard bars up to 50mm thick bars). Installation requires sliding the trolley over the top of disassembled rack posts rather than clamping on, and reviewers across three independent YouTube channels describe a genuine multi-week process of dialing in each roller’s tension to the specific rack before the unit tracks smoothly. Once tuned, it’s frequently compared favorably to a dedicated Smith machine, though the tradeoff is cost: the trolley pair alone runs $899-999, and a full setup with ISO handles and weight horns reaches $1,150-1,200+.
