Gibbon Arms Cable Crossover Rack Attachment

We'll be straight with you. Every lever arm moves in an arc, so you feel less than the full weight of the plates loaded. The fix is length, and the Mammoth's lever runs 39" to 48.75", one of the longest you can buy. A longer lever means a flatter arc and less forward pull.

In our recommended setup you feel about 80% of the load, and up to about 90% with the horn moved closer to you. Most lever belt squats top out around 60%. A standalone machine costs $2,000+ and eats floor space. The Mammoth hangs on your rack. See the full felt load breakdown.

Yes, and watch it before you start. It covers the belt squat and the kickstand. The bolts are big, so have a large wrench or socket set handy.

One tip owners have flagged: don't skip the big washer that goes under the weight horn.

It fits 2x2, 2x3, and 3x3 uprights with either 5/8" or 1" holes. Just pick your hole size at checkout. The one thing to check is that your upright has holes on the side, since that's where the Mammoth mounts.

No side holes? The Wall-Mount Accessory gives you a dedicated belt squat station without tying up your rack. And if it still doesn't work out, you're covered by our 365-day no-drama returns.

Yes. The arm has about 10" of length adjustment, the horn moves, and you can mount it at different heights on your rack. Mount height matters most, especially for shorter lifters who need to clear the kickstand. Our mount height guide walks you through it.

Sharing with someone a lot taller or shorter than you? Dial in a setup for each of you, then switch mount height and arm length between users.

The Mammoth is rated to 900lbs, so the frame isn't your limit. Plate space on a single horn is. Add the Dual Mounted Weight Horns for more room, and they double as handles mid-rep.

Worth knowing: dual horns sit farther back, so felt load drops to about 65%. That's great for big numbers, but run the math before you chase a plate count.

The lever arm has a lifetime warranty, and the whole unit is rated to 900lbs. Check that your hardware is snug after the first few sessions.

The belt comes free with every Mammoth. It's padded so it doesn't dig into your hips, and it has 3 sets of D-rings on each side for a small, medium, or large fit. It's covered by a 1-year warranty, and plenty of owners use it for weighted dips too.

Yes. It sits at an angle when it's down, and a spring-loaded lever locks it firmly in place. It's 17" tall, so you start every rep standing and set the weight back down when you're done.

You can, and plenty of people start there. Here's what you get with the Mammoth: a 900lb rating, a kickstand so you start standing, a long adjustable lever, a lifetime warranty on the arm, and a padded belt. It mounts and comes off in seconds. No lumber runs, no guessing if it'll hold.

The horn takes Olympic plates and gives you 14" of loadable space. Iron or thin plates fit the most weight and give your knees the most clearance. Thick bumpers work, but they fill the horn fast and can crowd your stance. Standard 1" plates won't fit.

No rack? The Wall-Mount Accessory turns any solid wall into a belt squat station. Mount it into studs, never just drywall.

Can't drill? Owners also run the Mammoth on squat stands and yokes, as long as the uprights have side holes in 5/8" or 1".

Lookalikes can copy the shape, not the lever. The Mammoth's 39" to 48.75" arm is what gets you up to about 90% felt load. You also get a lifetime warranty on the arm, a real support team behind it, and hundreds of owner reviews. Garage Gym Reviews named it the best budget belt squat for a reason.
