    If you want to have a dumbbell set that you will never outgrow (unless you're a genetic freak) what are you waiting for? Be advised that these will void your warranty on the dumbbell handles. Looks amazing and is still fully functional, great for rows, working on pressing these beasts.

FAQs: QUICK-LOCK CUSTOM 165 LBS (74.8 KG) ADD-ON KIT

Do I need anything before using this kit?

How much weight does this add?

This kit adds 45 lbs (20 kg) to each dumbbell, bringing your total up to 165 lbs (74.8 kg) per hand.

Are the screws different from standard and long ones?

Built for Serious Strength Progression

This is the final stage in the Quick-Lock Dumbbell system, designed for lifters who have outgrown 120 lbs (54 kg). By adding 45 lbs (20 kg) per dumbbell, it allows you to continue progressive overload without needing new equipment.

Extra-Long Locking Screws for Maximum Safety

The included screws are longer and fully threaded, requiring full insertion for each adjustment. This ensures a tighter, more secure hold, critical when training at heavier weights.

Traditional Dumbbell Feel at Heavy Loads

Even at 165 lbs (74.8 kg), the system maintains the same balanced feel as a fixed dumbbell. This gives you better control, stability, and confidence during heavy presses and pulls.

Compact Heavyweight Solution

Instead of taking up space with multiple heavy dumbbells, this system keeps everything compact. You get extreme weight capacity without sacrificing floor space in your home gym.

Designed for Compatibility and Longevity

Engineered to work seamlessly with the 75 lb (34 kg) set and 120 lb (54 kg) Add-On Kit, this system builds on your existing setup. It's a long-term investment that grows with your strength. Backed by our Ironmaster lifetime warranty.

Please Note: Our Quick-Lock Adjustable Dumbbell Handles are originally engineered to support up to 120 lbs (54 kg). While this add-on kit allows you to reach 165 lbs (74.8 kg) capacity, any damage resulting from misuse, dropping, or improper handling will void the lifetime warranty on the original product.
