The VTS (Versa Trolley System) is a revolutionary rack attachment pair that transforms your squat rack or CrossFit rig into a versatile, multi-function training hub. Dubbed the "rack smith machine unit," it seamlessly accommodates your own barbell with a proprietary clamp system featuring UHMW rollers that protect against scratches and provide smooth movement.

With patented hex port system attachments, the VTS opens unlimited possibilities—from specialized barbells and single handles for iso-lateral movements to 3D adjustable handles, foot plates, and shoulder pad units. Installation is done by sliding the unit over the top of the rack posts, and the system uses safety latches to secure your barbell in place.

Quadrilateral Roller System

Eight UHMW rollers with high-grade bearings on all four sides allow smooth tracking under any load configuration, enabling unilateral single-handle movements and maximum versatility.

Hex Port Ecosystem

Proprietary hex ports allow attachment of multiple accessories including weight horns, handles, and future attachments. Many hex port accessories also work with other Bulletproof Fitness units, maximizing value and minimizing storage space.

Adjustable Roller Fit

Each roller has horizontal set screws for precise adjustment to your rack, ensuring a snug fit that minimizes play and uneven barbell paths during lifts.

Hardened Iron Hooks with Grip

Laser-cut hooks made of hardened iron feature rubber strips to protect your barbell and provide secure grip during latching and unlatching.

The VTS delivers versatility, stability, and smooth movement—transforming any compatible rack into a space-saving, cost-effective training facility.

Features
  • Eight UHMW Rollers with Bearings: Each VTS trolley features eight proprietary UHMW rollers with high-grade bearings on all four sides of the upright, enabling smooth travel under load and precise tracking for iso-lateral movements.
  • Quadrilateral Roller Design: Unlike traditional two-sided roller systems, the VTS is the first rack trolley with rollers on all four sides, allowing any combination of load and force to work smoothly without binding.

  • Wide Barbell Latch Design: Maximizes contact area to apply even pressure across your barbell, eliminating uneven barbell paths and ensuring stable lifting mechanics.
  • Front Latch Pin Safety Feature: A threaded pin adds rigidity to the barbell latch by bridging both sides, and acts as a hook stop to prevent over-rotation while serving as a safety catch during re-racking.
  • Horizontal Set Screw Adjustability: Each roller includes set screws for perfect rack fit adjustment, ensuring minimal play and adapting to your specific upright dimensions.
  • Hardened Iron Hooks with Rubber Grip: Laser-cut hooks provide maximum strength while rubber strips protect your barbell and add grip during latch engagement.

Product FAQs

What's the difference between VTS and VTS Lite?

The VTS weighs 24 lbs per side and features rollers on all four sides of your uprights, providing superior smoothness for iso-lateral movements and heavy unilateral work. The VTS Lite weighs 15 lbs per side with rollers on front and back only, making it ideal for smith machine movements and lighter exercises. Choose VTS for maximum versatility and control, or VTS Lite for a lighter, more affordable option focused on standard lifts.

Which hook option should I choose—front hole or hitch pin?

The front hole hook fits into hitch pin holes on your upright (1", 3/4", or 5/8") and offers multiple latching points for flexibility. Most customers prefer this for versatility. The hitch pin hook wraps around a horizontal hitch pin and is better if you experience muscle imbalances or injuries affecting bar levelness, as it provides a secure catch even if the bar tracks off-center. If your uprights have 5/8" holes and you struggle with imbalances, the hitch pin hook may be your best choice.

What size VTS do I need?

The VTS comes in three sizes: 3x3, 2x3, and 2x2, matching the width and depth of your rack uprights. Measure your uprights—the first number is width (2" or 3") and the second is depth (2" or 3"). The VTS is designed for 7' Olympic barbells and has been tested with a maximum 43" inside width for racks. Choose the size that matches your upright dimensions for proper fit and adjustment.

Will the VTS work with my barbell?

The VTS works with most standard 28-30mm Olympic barbells and 50mm thick barbells. Popular confirmed compatible bars include Rogue Ohio Power Bar, Rep Colorado Bar, Titan Fitness Safety Squat Bar, Texas Power Bar, Rogue Operator Bar, and many others. Bars that do NOT work include Rogue Transformer Bar, EliteFTS Multi-Grip Bars, Kabuki Kadillac Bar, and Rogue CB4. Check the full compatibility list on the product page, and note that compatibility may vary based on barbell design, coatings, and manufacturing tolerances. When in doubt, verify your specific barbell model before purchase.

Can the VTS be used on racks with functional trainers?

Yes, the VTS can work on some racks with functional trainers. On Rep setups, mounting the VTS with the barbell latch facing back and positioned above the functional trainer trolley provides adequate clearance. However, clearance varies by rack model. We recommend checking our dimension images and comparing your specific rack's functional trainer placement before purchase. Contact us if you need help confirming compatibility with your setup.

How is the VTS installed?

The VTS must be installed by sliding the unit over the top of your rack posts. This is different from the VTS Lite, which can be installed around the uprights. Installation must be done carefully to ensure the unit sits evenly and the rollers are properly adjusted using the horizontal set screws for a snug fit. Once installed, your rack must be firmly mounted in place to prevent tipping based on weight and angle of pull.

What safety precautions should I follow with the VTS?

The VTS must be used with safety stops such as set hitch pins to prevent injury. The unit is not designed to be dropped, as doing so can result in damage to rollers and hardware and may void warranty. The system is designed with the assumption that your rack is firmly mounted and secured in place. Always ensure your rack cannot tip based on the weight and angle of pull you're using. Purchase of the VTS assumes you have read and understand all risks associated with its use.

What attachments and accessories work with the VTS?

The VTS features a patented hex port system allowing attachment of numerous accessories including ISO Handles, weight horns, a specialized VTS feather barbell, 3D adjustable handles, foot plates, shoulder pad units for leg press and hack squats, and more. Many hex port accessories also work with other Bulletproof Fitness units like the Isolator, saving money and minimizing storage space. Check the VTS accessories section for the full range of compatible attachments available.

    Awesome!

    I've had the VTS (VTS, Feather Barbell, ISO Handles, Weight Horns, and Hitch Pin & Hole Hooks) for over a month now. I absolutely love it! I have it attached to my Rogue Monster Lite RML-90Slim Rack and it works perfectly for my needs. I have limited space, and a dicked up shoulder, and this allows me to do so many movements I was unable to do without it. I use it for every workout. As noted in several reviews, it does take some time to get it all dialed in, but once completed it all runs smoothly. There are several YouTube videos to assist you…..watch them! The customer service is amazing. You actually talk/text directly with the owners and their response is prompt. Nicole is the best! I completely recommend this product. I’m looking forward to more attachments. Thank you!
