{"type":"firestarter.listing","listing":{"id":"lst_RR3scH6h","product_name":"Hydra / Manticore Lat Pulldown Plate Loaded to Selectorized Upgrade Kit","category":null,"description":"Tired of loading and unloading plates every time you switch exercises? Upgrade your 84” or 90” Hydra or Manticore Lat Pulldown/Low Row Rack Attachment to a sleek, selectorized system with this Upgrade Kit. With a 210lb weight stack, you’ll get silky-smooth reps, whether building a back as wide as a barn door or chasing that perfect lat spread. And since this upgrade integrates directly into your existing rack attachment, buying a whole new setup is unnecessary, saving you time &amp; effort.The upgrade process? Surprisingly simple. Choose the height that matches your Lat Pull/Low Row height (84\" or 90\"). Then, swap out your old plate-loaded system for the new weight stack components, and boom — you’re the proud owner of a selectorized lat pulldown/low row station!This means no more fumbling with weight plates (besides change plates, but we know you're up to the task) — just pop the pin in and lift. Welcome to the future, friend.IMPORTANT: This upgrade is only compatible with the 84” &amp; 90” Plate Loaded Hydra/Manticore Lat Pulldown &amp; Low Row Rack Attachment that mounts onto the Rear Base Stabilizer with a channel bracket and has height adjustment holes at the top of the guide rods instead of the bottom. If you’re still unsure, email us your quote/invoice, and we'll confirm its compatibility.","images":["https://cdn.shopify.com/s/files/1/0654/3346/9125/files/UPGRD-HYDMTC-LA-RA-PRNT-carousel-primary-1.jpg?v=1764591929","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/UPGRD-HYDMTC-LA-RA-PRNT-carousel-primary.jpg?v=1764591929"],"price":844.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:45.490Z"},"share_url":"https://firestarter.network/l/lst_RR3scH6h","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
