    I've had the standard set of Ironmaster dumbbells for just over a year and couldn't be happier… until the day I needed extra weight! I ordered the 120 lbs add on kit and waited in excitement for them to arrive. 2 days later they were there ready to be lifted. Let me say this, the packaging is very, very good. But I soon had it off and I was ready to roll. The add on kit is basically 4 longer locking screws and (more importantly) 4 larger weight plates. Everything was perfect and now I can't wait until I need the 165 lbs add on kit. It might be a while though!

    I just recently purchased the add-on kit for the dumbbells. They are the same excellent quality as the starter set. Don't be fooled into buying cheaper alternatives, these will last forever!

    Perfect addition to the 75 pound dumbbell pair. If you're going to be doing bench press this is an awesome option to have. I don't believe that I'll need to go higher in weight but if you do they have a 165 pound add-on kit which is pretty amazing. I love my extension kit and use it on my leg developer which hooks on to my super bench perfect for fast change outs while doing leg extensions and leg curls. I love the products and absolutely recommend them to anyone wanting to build a gym.

FAQs: QUICK-LOCK ADD-ON KIT 120 LBS (54.4 KG)

Do I need the Quick-Lock Dumbbells Set to use this kit?

Can I adjust weights gradually or is it all-or-nothing?

You can fully customise your weight by combining existing plates with the add-on plates for gradual progression.

Are the heavier dumbbells still compact?

Yes, even at 120 lbs (54.4 kg), each dumbbell remains compact at approximately 18.25" (47 cm) in length.

Massive Strength Upgrade

This kit adds 45 lbs (20 kg) per dumbbell, bringing your total up to 120 lbs (54 kg) each. It allows you to continue progressing without needing a completely new set of weights. Ideal for serious lifters pushing beyond intermediate limits.

Patented Quick-Lock System

The longer locking screws secure plates with just a quick quarter to three-quarter turn. Weight changes are fast, simple, and reliable so you can stay focused on your workout. No tools, no hassle.

Precision Interlocking Plates

Each plate is precision-cast and hand-machined to interlock seamlessly. This design prevents shifting or disengagement during use, giving you a stable and controlled lifting experience even at maximum weight.

Compact Yet Heavy-Duty Design

Despite the added weight, the system remains compact and balanced. The square plate design allows comfortable thigh support when setting up lifts, while maintaining full range of motion during exercises.
