Do you already have an Ironmaster Quick-Lock Adjustable Dumbbell Set in your home gym? If you want to make it work even harder for you, so you can lift heavier and add more exercises into your sessions, this add-on kit is the solution.
Ironmaster is one of the oldest and best-loved home gym equipment manufacturers. We’re trusted by customers ranging from Pro bodybuilders to guys kitting out tiny home gyms in their garage.
This add-on kit adds 45 lbs (20.4 kg) to each dumbbell for a maximum of 120 lbs (54.4 kg). You can put the “big” plates on the handles first or add them after the original weight plates. Also included with the Ironmaster Quick-Lock Adjustable Dumbbell Add-on Kit are four longer locking screws that accommodate the extra plates.
This is an indispensable add-on for heavy weight trainers, professional athletes and beginners advancing into their programmes.
“This is an essential addition to the standard dumbbell kit. The dumbbells are excellent. Tough, good grip, no fear of break in case of a drop, fast change of weights. Best design at the best price. The seller is fast, friendly and very helpful.” – Chris
Why the QLDB 120 lbs Add-On Kit?
Our quick-lock adjustable dumbbells are a flagship product. They’re everything we stand for as a brand. Uncompromising quality. Strength and durability. No-nonsense, beautiful kit. Equipment which works as hard as you do.
If you’re a QLDB owner, you know what we’re talking about. But what happens when you want more from your equipment?
Increase your potential
Choosing the Ironmaster Quick-Lock Adjustable Dumbbell Add-on Kit for your home gym means you can expand your dumbbell weight up to 120 lbs (54.4 kg) per dumbbell, in 2.5 lbs (1.1 kg) increments. This makes more sense than buying racks of fixed dumbbells that cost more and take up too much valuable space!
Unbeatable Quality
This high-quality add-on kit is made from steel and iron, with no plastic parts or small bits of metal. The high-grade steel handles are chrome plated, and each weight plate is precision cast and hand machined.
World’s Strongest Adjustable Dumbbells?
Are the Quick-Lock Adjustable Dumbbells the world’s strongest adjustable dumbbells? It may be a bold claim, but we back it up by providing a lifetime warranty. This is commercial-quality kit for your home gym. We’ve thrown everything at these dumbbells, and they still work!
This is equipment designed and developed by guys who love training. And it’s used by some of the strongest athletes in the world.
“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.” – Jake

With this add-on, you can add some serious weight to your Ironmaster Adjustable Dumbbells. Drop the weight at the end of your set, if that’s your style. Our dumbbells are so strong and durable that they can withstand impact. No rattling plates or wobbling parts. And the locking system is solid.
Load them up, lift them, and set yourself up for your first rep.

I just purchased the add-on plates to take each dumbbell up to 120lb and I’m just as happy with this purchase as I am with the original 75lb kit. The larger plates do make it quicker to stack up to moderate and heavier weights.

LOVE the 120# Add-On Kit for QLDBs. I’ve been waiting forever because of the COVID issues but it was worth it – this made my year! Worked out last night – now I have a complete weight range for anything. Since I have two pairs of the QLDs – I can make one go past 50 and the other pair go lighter. Have extra 5# to make it work. Amazing product – this is top-gym on-par excellence for the money. Love the ruggedness and feel. You guys rock – I can’t say enough great things about you!

It just adds more flexibility to the rest of my product. I am thinking of adding some more dumbbells to make setup quicker though. I might have an extra set to just have these heavier weights already attached so I don’t have to worry about moving them on and off so much.

The Ironmaster dumbbells are an excellent addition to any home gym. Good grip and easy change of weights. Valley Fitness were quick to respond to any questions and resolve any issues I had.

Damn these are good!
Once these bad boys are added onto the regular iron masters, you have weights going from 34-54kgs!
Super solid, super heavy and a very worthy investment.

I have their adjustable dumbbells. The design is genius. They feel like actual dumbbells you use at the gym, yet adjustable. There are no cheap plastic parts and are solid as a rock. I highly recommend them to all my friends who are in the market for adjustable dumbbells.

Perfect addition
Perfect addition to the 75 pound dumbbell pair. If you’re going to be doing benchpress 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 165 pound ad on kit to 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. Love the products and absolutely recommend them to anyone wanting to build a gym.

Check your ego
This is probably the max most men will ever need! Like the 75 sets, these have a high build quality and are very durable and accurate. Perfectly made to allow you to add more weight with less hassle or stripping down to just the handles. If you plan to get strong these are a nice addition.

Hit the Lottery…
After entering several Ironmaster Lotteries, I finally hit the jackpot. The 120 pound add-on kit completes my home gym. This is a great product, and now it’s now super easy to get between 75 and 120 pounds for some heavier benching or some Kroc Rows. They feel great, and they are durable. I’ve dropped mine a few times after a set (onto a rubber mat), and they are rock solid. The best part is being able to have what amounts to a full set of dumbbells in a compact space. Changing weight is still very easy. But I have two sets of handles for even quicker drop sets… which is really nice. This is a must have.

Add on Kit to 120 LBS For Quick- Lock Dummbells
I Absolutely love the Add on kit for my Ironmaster Dummbell set. I now have the ability to go from a set of 5 lbs-120 lbs set of dummbells. So simple and so much space saving for my basement gym. Highly recommend for those that need extra weight to add to their training regime.

Not just for Dumbbells
The Quick-lock family of products is really well thought out and a great space and money saver. These are high quality products and I never worry about dropping them too hard. The add on kit increased the dumbbell weight to as much as I will ever need. But it also increased the kettlebell weight (due to the longer locking screws). Great overall system.

Quality materials
These weights match up to each other very well and are well made. I can definitely foresee these screws and weights lasting a long time

Excellent quality as expected
Like all Ironmaster products, these deliver on high quality.
My dumbells now are heavy enough for everything I can handle, no complaints!

Yup, these do the thing. Pretty awesome being able to have 120lb DBs to grow into while so many other adjustable DB companies cap you around 90lbs. They’re also super secure and have 0 rattle while you move them.

Makes life easier
The 22.5lb plates make loading up the kettlebells so much easier. Also love doing farmer carries with the dumbbells and heavy handle kit with these. Quality product as always. Thanks.

More Dumbbell Weight Than Gyms Near Me
The original 75 pounds per dumbbell got the job done, but I always knew I would get the expansion kit when it was more available. It makes loading weight for 55 pounds and above so much easier. Putting on the big 22.5 pound weights saves time and it’s quicker to go up from there. Going between 75-120 pounds for presses, RDLs, etc., opens more progression and feels sturdy when using the heavier weights. Most gyms near me only have dumbbells up to 100 pounds so being able to go above that is so convention. Will definitely have to get the 165 expansion kit one day.
