If your lift is low enough you can use them. I almost did, but in my block the groove in the lifter would have been about .055 or .060 from the bottom of the bore and I didn't want to take a chance that the lifter could catch the bottom of the lifter bore.
I was going to use them to save weight, but when I weighed them the Dumbbells were only a gram or two lighter than a regular lifter.
