More weight than I need, which is a good thing!
I do use over 100 pounds on a couple lifts, so an expansion was needed to the base set. I also have the heavy handles so 135 lbs for each dumbbell is more than enough if you put everything on at once. Great addition. Very sturdy with the longer quick lock screws.

Great Upgrade
Seamless upgrade to a great product.

Versatile add on
Adds a ton of versatility to the already amazing base adjustable dumbell set. Now I can do heavy rows and quickly adjust the weight for presses.

The best
No need for an entire collection of dumbells after purchasing the add on kit. High quality solid thread engagement. Compact design does not limit range of motion especially at the top of the rep. These will not come apart mid rep and feel solid. I have hit failure and dropped them to the floor with no worries. My only regret was not purchasing the add on years ago as 75lbs dumbells was really limiting my workouts.

Great addition to the 75lbs dumbbells
If you have the 75lbs dumbbells and are strong enough, getting this add on kit is a no brainer. Having to change out the locking screws depending on how much weight you have on is slightly inconvenient but that is such a small inconvenience to pay for having adjustable dumbbells that look and feel right.

great addition for more weight
This is a great addition for those wanting more than 75lbs. From incline bench to shoulder shrugs to hanging squats (note holding the dumbbells to the side takes lots of hand strength at heavier weights) Easy to add weights and works with several other bars and the kettle bell. If the 75's aren't enough for what you want to do then get this set or the heavy handle add on weight set or both. You likely wont need anything else dumbbell related ever again.

super kit d'ajout
Translated: this kit is great for those who are limited in space and not too much of a concern for those who sometimes work in bi-sets or tri-sets because it is still quite quick to change the load without wasting too much time for chain training. Original: il est génial ce kit pour ceux qui sont restreint en espace et pas trop d'inquiétude pour ceux qui travail parfois en bi-sets ou en tri-sets car c'est quand même assez rapide de changer la charge sans trop perdre de temps pour enchainer les entrainements

Great Addition to My Gym!
Great addition to my workout! I've just started to go heavier than 75 lbs on a few exercises - actually went up to 95 pounds today doing hanging squats. The add on plates make the dumbells seem even more sturdy. Great having a pair of dumbells that go up to 120 pounds and only take up the space of two dumbells.

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.

Add on lot to 120#
This kit is Great! Easy to use and I have more weight to play with,

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.

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!

Moar Powah
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.

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.

120lbs add on kit
Excellent quality and fast shipping. Thank you.

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.

Quality product
Quality product, although prices have gotten out of control. These are without a doubt the best adjustable dumbbells on the market today. I wish they were made here, but you can’t have everything I guess. The powder coat holds up well. The guys at Ironmaster were even able to accommodate my request to have 5# plates shipped instead of the 22.5# bricks. Good company, quality product. I did have to enter 4 or 5 lotteries, but it finally happened! So be patient.

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.

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.

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.

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.

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!

Great add-on Bought these the same time I bought the regular dumb bell package. One of the 45's didn't fit quite right and snug due to a factory defect and Iron Master immediately shipped me another one out. (Kudos to the customer service too!) Can't very well deduct a star for that. "Stuff" happens sometimes, the important thing is they remedied it with no hassles like the pros they are. These are very durable. The best!

So Simple! I cannot believe no one has ever thought of these Quick Lock Dumbbells. The whole system for changing the weights is so simple. The plates are thin and easily stack. The rack is easy to assemble, sturdy, and convenient for organizing everything. I looked at the other adjustable dumbbell systems and they were too complicated and not durable. These Quick Lock Dumbbells are robust and reliable.

So glad we added these to our weights. It has made it easier to add weight to the kettlebells. Mostly I didn't like having to move the locks from the dumbbells to the kettlebells then back.

These are a lifesaver, so I can increase to higher amounts
