Reviews Summary
Customers say this weight stack upgrade significantly improves their rack's functionality and stability. Many reviews mention the smooth operation and convenience of pin-selected weight changes, especially for drop sets and partner workouts. Users frequently recommend upgrading to the heavier weight stack during initial purchase rather than adding it later. Common feedback includes praise for the commercial-grade quality and solid construction. Several customers note the upgrade anchors their rack effectively, eliminating movement during pull-ups. Some mention minor issues with shipping damage to individually wrapped plates and suggest upgrading the included handles and bars for better quality.

    Extra weight helps

    Purchased the stack upgrade due to another persons review. Saying it really makes the rack sturdy and it does. I have the 30” crossmembers with 80” uprights. When I do pull ups the rack does not budge. And, I don’t have it anchored to floor or wall.

    Perfect Addition from me

    I started out looking for a functional trainer but decided that for me and my son this was the better choice. It fits our space and our needs. Went with the added weight on the stack and it went together with no issues. Solid.

    Great upgrade

    I absolutely love this upgrade for my rack. I have lots of attachments, but this has been my best addition to date.

    Weight stack upgrade

    I got it, I love it, but I don’t think I’ll ever max the stack out!
