Spartaks Strength KB24 Premium Weight Stacks ($4.00/lb)

The upgrade your stack deserves. The Spartaks KB24 Premium Weight Stack is built from a denser, higher-grade cast iron that delivers a noticeably smoother pull and a more consistent feel under load than standard weight plates. At 11 lbs per plate versus the regular 10 lb cast iron, the additional density means less air space, tighter tolerances, and a quieter, more controlled action through every rep.

The result is a cable system that feels more like a commercial gym machine and less like a home setup — less clank, less bounce, more consistent resistance from the first rep to the last. Sold by the pound and compatible with all KB24 Series racks, upgradable to 300 lbs per side.

• Premium Stack Upgrades — Add high-grade resistance to your KB24 weight stack in 11 lb increments, up to 300 lbs per side.
• Quieter, Smoother Training — Denser plates reduce clank and stack bounce, for a more controlled, commercial-grade cable feel.
• Long-Term Investment — Higher-grade iron holds its tolerances longer, maintaining consistent performance through years of heavy use.
