Bells Of Steel Hydra Four Post Power Rack - Prebuilt (3" x 3", ⅝" Holes) - 4-PST-HDR-PREBLT

The 4 Post Power Rack is to home gyms, what maple syrup is to Canada: world-renowned, and the sign of impeccable taste. *chef's kiss*

It outlasts heavy squats, handles big bench presses and withstands chin-ups with 8 kids hanging onto your waist - just bolt it down before you go trying for that new chin-up PR. The uprights measure true 3" x 3" which is EXACTLY 76.2mm x 76.2mm, instead of the typical 75mm x 75mm uprights of other brands' imported racks.

By matching the same tubing specs as many of our American competitors, you can mix and match attachments freely without needing to stick to one brand - hello, open ecosystem! Built with modular components, so you can expand later with Hydra components or divide it into two smaller Hydra racks to accommodate a new home gym space or team workouts with your swolemate.

What our Experts Think

• A flagship “buy once, build forever” rack platform. The Hydra Four Post Power Rack is built on a true 3" × 3" steel frame with ⅝" holes, designed for heavy barbell training, attachments, and long-term expansion in serious home gyms.
• Designed for maximum stability in a 4-post footprint. The rear uprights and crossmembers create a rigid structure that handles squats, bench press, and pull-ups with minimal sway, even under heavy loads.
• Fully modular ecosystem advantage. This rack is part of a larger Hydra system, meaning it can be expanded with lat pulldowns, cable towers, storage, and specialty attachments over time instead of being replaced later.
• Commercial-level strength rating. Engineered for roughly ~1,000 lb capacity with heavy-gauge steel construction, making it suitable for advanced lifters and progressive overload training cycles.
• Attachment-friendly standardization. The 3" × 3", ⅝" hole spacing allows broad compatibility within the Hydra ecosystem and other matching-spec attachments, giving it strong long-term flexibility.
• Includes full rack essentials out of the box. Typically shipped with J-cups, safeties, pull-up bar, and structural crossmembers so it functions as a complete training station immediately.
• Best suited for: serious home gym owners, strength athletes, and users who want a permanent training hub that can evolve into a full gym system over time.
