{"type":"firestarter.listing","listing":{"id":"lst_thJ40wUA","product_name":"Half Rack Conversion Kits","category":null,"description":"Your squat stand was a great first date. This is the glow-up.The Squat Stand to Half Rack Conversion Kit upgrades your setup with rear uprights and crossmembers—giving you more stability, more storage, and way more ways to train, without eating up extra space.Re-racking heavy lifts feels more solid. Attachments hit different. And your rack? Way less “minimalist,” way more “do-it-all.”Load it up with plate storage, add cables, run bands, or train front and back at the same time. The Hydra ecosystem is built to grow with you—so you’re never boxed in.Why replace the whole rack when you can just… make it better?Like all Hydra and Manticore gear, this upgrade is fully modular. Today it’s a half rack. Tomorrow, who knows—full rack, cable tower, lifting empire.Built from 3” x 3”, 11-gauge steel with 5/8” to 1\" holes (depending on your mythical beast rack of choice), it plays nice with a massive range of attachments.Built like a tank (because it is). Same heavy-duty steel, same durable powder coat, same confidence under heavy weight.","images":["https://cdn.shopify.com/s/files/1/0654/3346/9125/files/hdr-hlf-rck-conv-set-01.jpg?v=1773745581","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/mtc-hlf-rck-conv-set-01.jpg?v=1773745581"],"price":339.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:45.239Z"},"share_url":"https://firestarter.network/l/lst_thJ40wUA","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
