⚠️ PRESALE INFO – READ BEFORE ORDERING
This product is available on a two-week presale. Orders placed during this time are guaranteed to be included in our next production run. After the presale ends, you can still order, but inventory is limited to the extra quantity we purchase—and availability is not guaranteed.
If you order after the presale, your item may take longer to ship depending on remaining stock levels.
⚠️ Important Note: Pricing is subject to change due to potential tariff increases on imported materials. Locking in your order during the presale not only guarantees availability—but also protects you from possible price hikes.
To secure your spot and get your gear sooner, we strongly recommend ordering during the presale window.

FEATURES
Key Features:
• Fits Exactly Like the Original – Same outer diameter. Slides into the Isolator unit just like the stock arm. No fuss.
• Length Adjustability – Slide and lock to increase the effective torque and resistance. It’s like turning up gravity.
• Compatible with Any of Our Weight Horns – Traditional single horn? Great. New dual horn? Even better.
• Rubber Bump Stop Built In – Protect your rack’s crossmember when you’re training like a savage and the weight arm makes contact.
WHY IT EXISTS
The original Isolator weight arm was designed with a 1:1 lever-to-load ratio—perfect for isolation movements like leg extensions and curls for most lifters.
But not all lifter and now that we’ve unleashed the Iso Arms for full compound movement madness, you’re gonna need more firepower for sure!
Enter: the Adjustable Weight Arm.
WHY YOU'LL PROBABLY NEED IT
Why You’ll Probably Need It
Let’s keep it real:
• Many compound movements with the Iso Arms require more weight than the short stock arm can deliver.
• Certain movements—especially presses, dips, rows—may feel biomechanically off if you don’t have the weight distance dialed in.
• You’ll likely need more load and better leverage. This solves both.
That’s why we strongly recommend:
• At minimum: get the Adjustable Weight Arm
• For optimal performance: get the Adjustable Weight Arm + Dual Weight Horn
Because while you can slide your iso sleeves down to the hinge to increase resistance, some movements just don’t feel right starting way down there. And we want your setup to feel like a machine—not a workaround.

Bundle Smart, Lift Smarter
Already picked up our Dual Weight Horn? You’re halfway there. Pair it with the Adjustable Arm for max load potential and beautiful weight distribution.
Did you get the Adjustable Multi Horn? Good news: you already have our upgraded rotational shaft, which is mandatory when using either the dual weight horns or longer weight arm.
WRAP UP
The Arm That Makes the Arms Work
If you’re going all in on the Iso Arms—or building out a leverage-based setup that actually challenges your strength—this is the no-brainer add-on.
More adjustability. More load capacity. More versatility.
Since starting length is the same as your original isolator arm you can leave this on for normal isolator movements and then when slap the ISO arms on you just pull that pin and grab the length needed with no added setup time or fuss!
The Adjustable Weight Arm isn’t just nice to have. For most lifters, it’s essential.
