KEY FEATURES

READY TO COMPLETE YOUR FORCE USA G20™

If you’re looking to make more strength gains and dominate every workout, then add the Force USA G20™ All-In-One Trainer Upgrade Kit to your set-up. It includes:

  • 2 x Jammer Arms that can be attached to the uprights for Bench Press, Shoulder Press and explosive work - finished with a high grade black powder coating.
  • Leg Extension / Leg Curl Attachment is made with durable high-density sweat-resistant foam to help you isolate the Quads, Glutes and Hips.
  • Convenient Dip Bars for the front of your unit will help to build strength in your Chest, Shoulders and Triceps - finished with a high grade black powder coating.

SPECIFICATIONS

*Please note: With the G20 Base (F-G20), the jammer arms are attachable to the uprights at a maximum height of 130cm. This is because the original model lacks westside hole spacing throughout the entire height of the upright. Should you have any additional inquiries regarding these limitations, please don't hesitate to get in touch with our sales team.

    Excellent Kit

    What a perfect kit for my G20 Pro!
    All attachments work very well, fit perfectly, the build is solid and sturdy. I am very happy with all 3 attachments - no shake, no wobbling. The dip bars just "freeze" under my weight and become rock solid.
    I had to scratch my head a bit deciphering the instructions, so here is the decoding table for you:
    1 stands for "P", 2 - for "Q", 3 - "R", 4 - "S", 5 - "T", 6 - "U", 7 - "V", 8 - "W", 9 - X", 0 - "O".
    So when you see "SV" in the assembly diagram, you should convert it into 47, which is the "Handle Left Welding".

    Love the jammer arms

    The jammer arms and dip handles are really good. They connect to the rack with no movement at all, it feels like they are part of the rack. I don't know if I will ever use the leg curl attachment but the pads feel very nice. This stuff takes up a lot of space when not in use. I ended up hanging the jammer arms from the hooks in the rack, they don't seem to get in the way.
    The jammer arms can be mounted at any height on the g20 pro

    Hi Greg,

    Disappointed

    I love the g20 gym and all it had to offer and was really only after the dip arm attachments but after being told i was unable to purchase them on there own i had to buy this bundle package which isn't cheap. Unfortunately as stated by another customer there is a major design flaw with the jammer arms, they can not be mounted from anywhere from notch 1-10 so for anyone of an average to tall height these lovely crafted pieces are just now an expensive paper weight :/ pretty disappointing

    Hi Shane,

    Thank you for sharing your positive feedback for the G20 however, we apologize for the inconvenience caused by the bundle package and the design flaw of the jammer arms. A member of our team will reach out to you to further assist you.

    Kind regards,

    Buyer Beware

    Whilst these are good quality attachments, well made, unfortunately the jammer arms have a major design flaw, they simply cannot be mounted high enough. The spacing suits the lower end of the G20 uprights, not the upper, so you cannot use these sitting on a bench or standing, and if you are tall, you can barely use them sitting on the floor. They are basically redundant. Very disappointed in these as they would have made a great addition.

    Hi Rhys,

    Thank you for your feedback and again our sincerest apologies for the issues with your order.

    We were unfortunately unaware of the limitations regarding version compatibility of the Jammer Arms at your time of purchase. We understand that this has been resolved with you privately and if there is anything else we can help with please do not hesitate to get in touch and we will gladly assist.

    Kind Regards,
    GAF Team
