M4-2.0 Ultra/Standard Weight Stack Upgrade Kit
Designed exclusively for existing M4-2.0 Ultra/Standard owners who wish to upgrade their unit to the Elite version,this Weight Upgrade Kit elevates your rack into a more powerful, flexible, and fully refined training system. Built specifically for the M4-2.0 Ultra/Standard frame and pulley path, this kit is not compatible with any other racks or trainers.
Dual-Stage Resistance, One Seamless System
This upgrade combines a 130 lb selectorized weight stack with a stainless steel add-on weight holder, giving you both precision control and heavy-load potential in one clean setup.
- 130 lb Weight Stack (10 lb increments)
Featuring 13 plates at 10 lb per increment, the stack allows fast, accurate resistance changes with a simple pin—ideal for functional training, isolation work, and progressive overload. - Weight Holder
Each side supports up to 155 lb of additional plates, unlocking higher resistance for heavy pulls, presses, and lower-body movements when you’re ready to push beyond the stack. Built to grow with you, this setup accommodates users from beginner to advanced fitness levels.
Once you experience stack-based training, going back to constant plate swapping simply doesn’t make sense.
4 PACKAGES INCLUDED:
-
- 26 × 10 lb Weight stack plates (260 lb total)
- 2 × Weight holders
- 2 × Weight selector pins and Insert lifting rods
- 1 × Installation Manual
