Instant Power Switch: Weights Changed in 10 Seconds Flat
This is the ultimate tool for beating inertia. Instead of fumbling with heavy plates, you just pull the pin and pick your weight. That’s it! We’re talking about 10-second weight swaps that let you maintain killer momentum for drop sets and keep your head fully in the training flow state. By taking the chore out of lifting, we lower the mental barrier to the floor. You’ll find it easier than ever to show up, skip the excuses, and build the consistent, confident fitness habit you’ve always wanted.

PRODUCT OVERVIEW
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
