MODEL: WS90
The Revolution 90kg Weight Stack Upgrade is built for those who have outgrown the standard resistance on their RFT300 Functional Trainer and want more room to progress. By adding an extra 31.5kg per side, it increases each weight tower to a full 90kg, giving you the capacity to train heavier across presses, rows, pulldowns, cable squats and functional movements. It’s ideal for strength-focused programs, progressive overload training and high-intensity sessions where increased resistance is essential for continued gains. Whether you’re working on raw strength or controlled hypertrophy, the added load allows you to challenge yourself without needing to change machines.
Each plate is made from solid steel and precision machined on all six sides to ensure a consistent fit and smooth travel along the guide rods. The matte black powder-coated finish adds durability while helping protect against wear and corrosion over time. Designed specifically for the RFT300, the upgrade integrates seamlessly with the existing system, maintaining the machine’s natural cable feel and balance. Once installed, it delivers a stable, commercial-grade training experience that supports long-term progression in both home and professional gym environments.
