ISOLATOR Cam

Isolator Cam Core Product

What used to be just another hex port on your Isolator now has a serious glow-up. The Bulletproof Isolator Cam transforms your setup into the first-ever universal cam system for rack attachments—giving you both form and function in one welded masterpiece.

Instead of a plain port, the Isolator Cam features a welded, laser-cut cam on the outside—leaving the inside open for your ISO arms or other attachments. The result? More versatility, more functionality, and a far better-looking setup.

What Will This Cam Actually Feel Like?

Cable ratios and felt load are not the same thing. What you actually feel depends on leverage: the distance from the cam’s rotation point to the end of the cam, compared to the distance from that same rotation point to where your leg pad, curl arm, or attachment is positioned.

Because the regular Isolator Cam is just under half the length of the lever arm, many common setups will feel lighter than people expect if they are only thinking about cable ratios.

Bottom line: if you buy the regular cam by itself, most leg movements will feel around half of the loaded weight, while preacher curls and other higher arm positions will feel heavier.

Function That Looks This Good Should Be Illegal

Most cams look like they were cut from farm equipment. Ours? Precision laser-cut for both performance and aesthetics. It’s lighter, stronger, and actually adds to your rack’s visual appeal.

But looks aside, this cam delivers a true cam-based resistance profile, eliminating the linear drag of lever-weight systems. Translation: resistance that matches your strength curve for smoother, smarter movement.

How Felt Load Really Works

Most of the industry talks about cable ratios or overall system ratios. That can be useful, but it still doesn’t tell you what the movement will actually feel like on the Isolator.

What matters most is felt load — and that is determined by leverage. Specifically:

• Distance from the rotation point to the end of the cam
• Distance from the rotation point to where your pad or attachment is positioned on the arm

If your pad is positioned farther out toward the end of the arm, the lever arm is longer, so the movement feels lighter. If your attachment sits higher up on the arm, closer to the rotation point, the lever is shorter, so the movement feels heavier.

That’s why the same cam can feel very different depending on your height, your setup, and the exercise you’re doing.

Regular Cam vs. Crossbow Cam

The Crossbow Cam is significantly larger than the regular cam, which gives it just over 2× the felt load. That makes it the better option for users who want heavier resistance directly from the cam.

The regular cam, on the other hand, offers a different advantage: it is smaller, lighter, easier to move, and more aesthetic. For many users, that compact design is a huge benefit—especially if they want to reposition the Isolator often.

So the decision is simple:

• Choose the Regular Cam if you want a cleaner, lighter, more compact setup and understand that many movements will feel lighter.
• Choose the Crossbow Cam if you want substantially more felt load directly from the cam itself.

Want More Resistance?

If you know you will overpower the regular cam on certain movements, you still have options.

You can increase effective resistance by using a floating pulley for a 1:2 setup, which doubles felt load. Or, if you want more direct resistance from the cam itself, step up to the Crossbow Cam.

Want to double resistance or play with ratios? Pair it with a floating pulley or connect it to:

• Bulletproof VTS (Versa Trolley System)
• Single Weight Horn Trolley Side Facing Pulley
• Your own cable or Voltra setup (DIY friendly)

Compact engineering, full-scale performance.

Isolator Guide Pulley Bracket Optional Add-On

Mounts to the bolts that connect your Isolator’s front and rear carriage. Positions two pulleys above or below the cam to keep your cable perfectly tangential — ensuring immediate, consistent resistance from rep one.

Bonus: forms a forgiving “cable cage” that can help guide the cable back into alignment if it’s slightly off-axis—but this can increase cable wear over time.

If the cable is way off from tangential alignment, the bracket won’t be able to correct it (and it won’t work as intended).

The World’s First Universal Cam System

Pair it with your Isolator and a Single Weight Horn Trolley Side Facing Pulley on a single upright to create a compact, full-function gym tower capable of:

• Reverse hypers
• Pullovers
• Leg extensions & curls
• Preacher curls & tricep extensions

Run 1:1 or 1:2 resistance setups depending on load source and pulley routing. Modular. Adaptable. Completely Bulletproof.

Specs & Highlights

• Compatibility: Bulletproof Isolator; works with VTS or Single Weight Horn Trolley Side Facing Pulley; adaptable to third-party cable/Voltra setups
• Design: Precision laser-cut steel with welded cam arm; open inner port retains accessory use
• Resistance: True cam-based profile that matches strength curves
• Felt Load: Typically around 50% on leg extensions/curls; heavier on higher arm positions like preacher curls
• Add-On: Guide Pulley Bracket for perfect cable tracking (recommended)
• Finish: Premium black powder coat with laser detailing

Why It Works

Standard lever arms create linear resistance. The Isolator Cam introduces a rotating cam profile that better aligns with human strength curves — heavier where you’re strong, lighter where you’re not.

Add the Guide Pulley Bracket to keep the cable tangent to the cam from the first millimeter of movement for perfectly smooth loading.
