Description
Quick-Lock Dumbbell - 120 lb Add on Kit includes the following:
- 4 each 22.5 lb plates
- 4 each long locking screws
Promotes Progression
Hardcore weightlifters, be prepared to meet your match! If you want to push your arm strength to its limit, take that leap of weight from 75lbs all the way to 120lbs on each dumbbell by adding 22.5 lb compact plates on each side of the handle.
- 60% increase. This add-on kit increases your load by a whopping 60 percent.
- Adjustability. You don't have to go up to 120lbs right away; you can mix and match your add-on plates with the original weights according to your capacity for gradual progress and so as not to shock your system.
- Compact design. Our dumbbells and add-on plates pack weight, not bulk. They do not limit your range of motion so you can get the most out of your workout.
Safe, Speedy and User-Friendly
Adjusting the weights on our dumbbells is easy and completely fool-proof. All our weight plates-including the ones in this add-on kit- won't fall off once you have locked them in place with the locking screws. Experience safety, comfort and convenience even as you challenge your body's breaking point.
- Strong and secure screws. The locking screws will not loosen while you are doing your workout with our patented Quick-Lock design.
- Quick screw-in and screw-out. Remove the screws with just a quarter to 3/4 turn so you can add or subtract plates and tightly screw them on in under 30 seconds.
- Interlocking plates. All our weight plates are hand-machined and designed to interlock so they don't automatically disengage when you take off the screws.
- Flat screw heads. The wide and flat surface of the screw heads hold the plates securely in place and won't hurt when you rest the dumbbells on your legs.
- Square weight plates. Likewise, our signature square-shaped plates allow you to rest them on your thighs comfortably in preparation for hoisting them up to lift position.
Contents and Product Inclusions
This Add-on Kit augments our already-powerful Quick-Lock adjustable dumbbell system with longer locking screws and heavy-duty weight plates that might even outlast your generation. They install quickly and conveniently so you can begin lifting in no time. It comes with:
- Four (4) each 22.5 lb weight plates that are precision cast and hand machined
- Four (4) each longer locking screws to accommodate load expansion
- Lifetime warranty for the original owner, for private use
You can put the "big" plates on the handles first (recommended) then you add or subtract the smaller plates to make smaller weight changes up and down. Very simple to use and works just like the standard plates and locking screws. The longer locking screws allow dumbbell sizes of 70-120lbs. The standard Quick-Lock dumbbell stand (sold separately or with the 75 lb set) will hold the full 120 lb dumbbells. Even with this serious amount of weight, the dumbbells are still compact. The dumbbells are just 18.25" long overall at the full 120 lbs.
The QLDB Stand will hold the pair of 120's and has storage on the lower shelf to hold the kit when not in use.
There is an option to build this kit with all 5 lb plates (18) instead of the four 22.5 lb plates. If you are interested in ordering this way, please contact our sales office.
Note: This is only an Add-on Kit. This requires the Ironmaster Quick-Lock Adjustable Dumbbell Handle Set or Dumbbell Handles from the Quick-Lock Adjustable Dumbbell 75 lb or 45 lb Sets to attach to. The image of the full set on the stand is for illustration purposes only.

Excellent quality and fast shipping. Thank you.

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.
Brad Lindstrom (WYOMING) | March 2nd, 2022
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.

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.
Kent (MO) | October 2nd, 2021
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.
William (Ca) | July 8th, 2021
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.

LOVE the 120# Add-On Kit for QLDs
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!

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.

Great add-on kit for the greatest adjustable dumbbells on the planet. Rock solid. Infinite star rating.
Matt (Monroe, WA) | December 12th, 2016
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. - From Amazon
Matt (Monroe, WA) | November 3rd, 2016
Five Stars. Works as advertised, same quality as base pieces. - From Amazon
Matt (Monroe, WA) | October 14th, 2016
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. - From Amazon
Reviewer | July 22nd, 2016
Nice Addition Just like Brad's review, I have had issues with the larger 22.5lb plates. They work consistently if I always put them on nearest the handle, so switching these in or out takes extra time. The extra weight is nice, but I find myself avoiding them due to the extra time it takes to set them up.
Matt (Monroe, WA) | January 8th, 2016
Such a nice addition to my 75 lb set. This set is so stable when you're putting up over 100lbs...which is essential for peace of mind and safety. Highly recommend this product. Definitely not cheap but well worth every penny. You get what you pay for...QUALITY! - From Amazon

Good concept poor execution in my experience For me, I have been using these 8-9 years and have almost always had problems getting the 150 add on kit to lock up as well as the 75 only kit. Inconsistencies with the hand ground plates seem to be the issues. some are more square than others. The company did send a new 150 add on set when notified so excellent service however, the 150 add on has just always been a guessing game as to whether or not they will lock up sufficiently without having to move around other plates.

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!
Kellen | August 24th, 2015
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.
Matt (Monroe, WA) | May 28th, 2015
Once upon a time, I became frustrated with my workout equipment and decided to purchase something that I knew was quality, would work very well, and last. That day - I went for a package deal from Ironmaster which included the 75lb Dumbbells & stand, super bench, dip & crunch attachments. Since then, I've used the equipment countless times, and have had zero substantive issues. Sure, the paint has chipped a little here & there - but I didn't buy 'em to look purty!
Getting stronger means pulling out the digital wallet to buy the upgrade kit. Spending another $200+ on an expansion kit might seem excessive, but if you've used Ironmaster gear - you know exactly what you're getting. Big, heavy, quality. In Ironmaster we trust.
If I ever grow out of these, I'll just workout with the neighbor's smart car. - From Amazon

Great add on to your dumbbells. I bought this add on for my Ironmaster dumbbells and love it. Great if you want heavy weights to build your big guns.
This add on attachment like all Iron master products is solid, well built and will last forever. - From Amazon
