Strength Shop Adjustable Dumbbell Extension Kits
Increase the Weight. Keep the System.
The Strength Shop Extension Kits allow you to upgrade your existing Adjustable Dumbbells to a higher weight range — without replacing the handles or starting from scratch.
Each kit includes precisely the components required to reach the next configuration. The adjustment mechanism, balance, and feel remain exactly the same: only the maximum capacity increases.
