    The Quick-Lock Dumbbell Add on Kit is made to bring your workouts up to several notches higher by adding 45 lbs to each dumbbell to bring them up to 120 lbs each. Includes four longer locking screws and four 22.5 lb weight plates. This is not the full set of dumbbells – only an add on kit. The image on the stand with a full set is for illustration purposes only.


    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.

    1. 60% increase. This add-on kit increases your load by a whopping 60 percent.
    2. 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.
    3. 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.

    1. Strong and secure screws. The locking screws will not loosen while you are doing your workout with our patented Quick-Lock design.
    2. 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.
    3. 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.
    4. 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.
    5. 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:

    1. Four (4) each 22.5 lb weight plates that are precision cast and hand machined
    2. Four (4) each longer locking screws to accommodate load expansion
    3. 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 19" 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.

    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

    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.

    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!

    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.

    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
