Description
Heavy Handle Plate Kit features:
- New innovative design to add more weight to the Quick-Lock Dumbbells.
- Kit comes with four 7.5 lb add on plates and hardware.
- This kit adds 15 lbs to each Quick-Lock Dumbbell handle. Works with all our dumbbell weight sizes.
- Increases empty handle weight from 5 lbs to 20 lbs to give a new range of weight.
- Does not add any extra size to the dumbbell, only more weight.
- Solid cast iron powder coated construction with precision machining.
- Note: The old Ironmaster Fat grip adapters will not fit with this kit in use but most rubber fat grips are shorter in length and will fit well. Inside grip space with the HH plates installed is about 5.18"
Expands Load Capacity, Not the Size
Designed to expand the capacity of your QLDB, these four additional handle plates bolt on the inside of the dumbbells against the backing plates, adding 15lbs to each dumbbell.
- Two pieces of 7.5lb-plates fit around the handles on the inside of each dumbbell, resulting in a total of 20lbs starting weight.
- Adds 15lbs to each Quick-Lock adjustable dumbbell making your 5-45 lb dumbbell set weigh 20-60 lbs. The 5-75 lb set becomes 20-90 lbs and your 5-120 lbs is amplified to 20-135 lbs.
- The new weight range this creates can be perfectly suited for many Ironmaster trainers who rarely go below 20 lbs anyway.
- Since these plates are placed on the inside of the dumbbell handles, your dumbbell will not increase in size, only the weight.
Spacious and Improves Weight Balance
Despite adding these heavy plates between the two backing plates on your dumbbell handle, there's still enough space on the handle for you to grip comfortably. You can also expect a better weight balance because these plates are placed closer to the dumbbell's center of gravity.
- Leaves a 5-inch grip space for holding the dumbbell.
- Better weight balance is established as the center becomes heavier.
Safe, Secure and Well-Crafted
The heavy handle plates stay in place by means of strong large screws that hold them together around the handles. Manufactured from powder-coated and precision-machined cast iron, you can be sure these plates will last a lifetime.
- The plates will not move or get dislodged once they are securely attached to the handles.
- The two halves of the plates are securely clamped and tightened around the handles using the two heavy-duty machine bolts and will never move.
- The plates are precision-machined from solid cast iron with black powder coating finish.
The 2 piece plates fit on the insides of the dumbbell handles like this. 20 lbs as pictured.
*The two halves clamp down on the round handle very securely and will not twist or move
once the two large machine bolts are tightened.*
5-45 lb dumbbell becomes 20-60 lbs as pictured.
5-75 lb dumbbell becomes 20-90 lbs as pictured.
5-120 lb dumbbell becomes 20-135 lbs as pictured.
Still plenty of grip room with more than 5" space. In fact, the dumbbells become better balanced with the weight closer to the center!
Note: Fat Grip Adapters won't fit around the handle once the Heavy Handle Plates are attached.

Ironmaster's team quickly resolved my issue with one of the Heavy Handle plate not tightening in place securely. To resolve this issue they sent me replacement plates that they tested with a return label for returning the one that I had an issue with.
The Heavy Handle Plate Kit feel evenly distributed, stable, and comfortable in my hands. I haven’t experienced any slipping of the heavy handle plates, even during my sweaty intensive workouts. The plate mechanism is smooth and doesn't take long to add/remove if needed.

The heavy handle kit is a great way to tack on some additional weight. Starting at 20 lbs is not a concern as I rarely do anything with less than 20. The plates fit securely inside the handles, with no rattling or movement. There is still ample size to get a grip on the dumbbell and doesn’t impede your hands at all. Another great item by IronMaster. I should have purchased these dumbbells years ago; they’ve become the most used items in my home gym.

Truly makes the adjustable dumbbells super easy to balance, while also making weight adjustments with less plates. Super satisfied 10/10
Doug (Maryland) | January 8th, 2025
This weight expansion kit feels a little pricey for the weight added (even on sale), but after maxing out my decade-old 75lb dumbbells, it was a sorely needed upgrade. I was concerned it would make the grip area a little cramped, but there's plenty of space for my hands. And as others have mentioned, it actually feels better with more weight closer to the center.

I got (2) sets since I’ve got (2) sets of the dumbbells.
Tom (Colorado) | August 2nd, 2024
A truly great product. Easily and securely adds weight to the dumbbell set. It also makes the dumbbell more secure since the grip length is reduced some. Still plenty of room for even the largest hands. A must purchase.
Tracy (VA) | July 1st, 2024
Makes the dumb bells starting weight right at the perfect place. You can't go wrong with this upgrade! Gives you a more narrow grip for comfort as well for smaller hands.
Grant (OH) | May 7th, 2024
Another truly great product from Ironmaster. This is a must-have: the way this kit reduces the overall size of the dumbbells is excellent for keeping the weight (and your grip) more centered at any poundage. More centered = less need to stabilize during movements = more strength, which is essential for getting the most out of your training. Install is fairly easy.

I echo the sentiments of most reviewers. The heavy handle kit is a nice upgrade, since it increases the weight while leaving the footprint the same. Narrowing the grip helps to center the dumbbell in the hands. I have pretty big hands which still fit comfortably in the narrowed grip. The added weight has the unanticipated benefit of challenging my grip more during DB rows.
My only critique is $159 pretty expensive for 30 lbs of iron. I'll get $159 worth of utility out of the purchase, so I'll keep the 5 star review.

The largest benefit to the heavy handle kit is decreasing the overall handle length. Solid construction. Extra weight was not really the reason I bought this as I already had bought the expansion kit. This add on is not for everyone, but the better grip and balance is noticeable.
Pat Lynch (Mass) | March 19th, 2024
This kit eliminates the width of the grip but adds on 15# from the get go. A must have in my opinion. Typical ironmaster quality throughout.
Mark (Indy) | March 5th, 2024
The heavy handle set is a must have. Not only does it give you 90lbs to work with but they also make the grip width perfect. Buy them, you’ll be glad you did.
Dan Mcdonald (Minnesota) | February 26th, 2024
I bought the iron master dumbbells awhile ago and the 70# max had run its limit. I bought the heavy handle kit and was exactly what I needed. Dumbbells handle great and the extra weight is balanced perfect. Would recommend. Easy install fast shipping.
Jay Rock (Florida) | February 21st, 2024
Great addition to DBs. Makes the handle a bit shorter more compact easier to center hands. No regrets in this purchase
John (Texas) | January 15th, 2024
Really improves the balance of the dumbbells, if you think the longer handles of the IM dumbbells is awkward I highly recommend.
Shane (Victoria, BC) | December 6th, 2023
I purchased directly from IM as it was cheaper than anywhere else in Canada. Shipping was fast! Product is excellent. Brings balance to the DB's that is much appreciated. Looking at the cost to weight ratio it is hard to justify, but when you consider the other benefits it is a no-brainer.

Ironmaster adjustable dumbells are the most solid, durable, highest quality adjustable DB ever created. The fact that these dbs can go up to 185lbs with the heavy handles in a home gym is insane. After adding the heavy handles, the total feel of the db do feel heavier. 100lbs without the heavy handles and 100lbs with the heavy handles feels different. The db feels more balanced, centered and denser. Overall it certainly feels heavier but whatever. weight is just a number. The heavier feel feels better.
In terms of the amount of space lost from the handle, I think it's significant but guys with much wider hands may not like the lost space. This is a must buy for anyone that owns these adjustable dbs. Price is very reasonable too

I've had my IM dumbbells for a long time, so I am very accustomed to the feel and function of this product. But as we all know, the handle is long and fully loaded the dumbbell length is also long. The folks over at IM keep innovating and bringing great products to market, and the heavy handle kit really delivers, imo. It shortens the handle length and makes the dumbbell more compact. If you're a long time IM dumbbell user, this kit takes some getting used to. At lower weights, it feels amazing. But as you progress towards heavier weights, it takes time to accustom yourself to the decreased handle length, because it does substantially affect the dynamics of how the dumbbell balances during the concentric/eccentric phases of the lifting cycle. Give yourself time to adjust, and in my experience with the kit added the IM dumbbells become an overall better, more enjoyable experience.

Like all good tools, a bit pricey but worth it.
Ironmaster dumbbells are the bomb, and these extra weights give them extra firepower.
Nicely machined and great fit.

The addition of the heavy handles have been well worth it. Not only do they allow you to add extra weight. They balance out the dumbbell very well. Highly recommend. Leave plenty of room for hands as well. No issue there.
Jonathon Lucas | March 22nd, 2023
I've had the Ironmaster adjustable dumbbells for quite a while, and the one thing that always bothered me was doing bench with them. Just due to how far out the weight was when going heavy, it made stabilizing them quite difficult (for me).
After adding on the heavy handle kit, the weight is significantly more closer to center, the dumbbells feel a lot more balanced and easy to control, and feels just miles better.
10/10, best upgrade

This is an affordable first step to increasing your weight set and is a must with the 75lb set.
Dalton | March 1st, 2023
Received the heavy handle kit the other day. Thank you for shipping it out to me so quickly. The kit gives the dumbbells a completely different feel, and I love the aesthetics. It's a huge win for both Ironmaster and those of us who have the dumbbells. The kit solidifies IM dumbbells as a permanent part of my workout routine. Have a great week!
Dan Tocci (NJ) | February 13th, 2023
Iv'e read all the reviews and can't say it any better, these plates are the perfect addition to my 75lb DB set. Thank you for making them available!
Ryan (Hercules, CA) | January 16th, 2023
These are a must if you have the DBs because they greatly improve the balance and feel in addition to upping the total weight.
There is still plenty of space for your hands, but I would rather have the plates be 5 lbs each so the minimum DB weight is 15 lbs rather then 20 lbs. Gaining that flexibility is more valuable to me because I also have the 120 lb add-on kit.

Super easy to install they give the handles a closer grip. Ironmaster products are the best. Thank you ironmaster for your good customer service and products.
Eric (Los Angeles) | December 27th, 2022
This plate kit really improves the dumbells overall. As long as you're ok losing the 5-15 lb range, it's a great upgrade. It improves the balance of the dumbells, reduces the number of plates needed, and increases the maximum weight.
Matt (Auburn, AL) | December 26th, 2022
Must have for your Ironmaster dumbbells. Better balance and feels like standard dumbbells.
jason | December 19th, 2022
almost perfect. If they want a better product they can round the inside edges a bit. It may not be an issue for smaller hands and smaller people but my wrists touch the edges if I bend them just a little when using these (hands are centered inside the open space). It's not going to stop me from using them, they are a pretty awesome addition for some extra weight. My set currently goes to 135 and that is enough for now. I don't use gloves when lifting but that will fix any potential issue with my wrists touching the edges of these when lifting. I would recommend these to anyone that can lift over 30 lbs. Silver lining is I can just train myself to keep my hands aligned better so still a win.
Dennis (Massachusetts) | September 9th, 2022
Excellent kit. I prefer the width of the handle with this addition. I put the bolt heads to line up with the arrow making it even easier to see the release side. That extra 15lb max/90lb dumbbells is great. You also don't have to add as many 5lb plates since you're starting at 20lb. You do lose the lower weights is the one downside.
