This is great option to add weight or another thing I have done is use it to jump between weight stack amounts. Adding weight overall to the stack is the main use for it. This is the original which is 6 inches long 2 inch diameter and is 8mm. Be sure to check if you have 8mm or 10mm stacks before you order.

This works great for me to stretch calves. After tearing achilles this is even more important for me.

Well made and good quality. I love the length as it works great for exercises like face pulls. American made by belt fed for rep.

This is inexpensive from amazon but works well for my purpose. I am putting 10 and 15 pound rogue dumbbell bumpers on it for the purpose of using with my loadable ez curl bar and this makes for great storage for that under my ez curl rack.

These are cool and super useful for me to get half jumps on my machines. I feel you do need two so you can get actual half jumps on the 10lb weight stack plates.

If you need extra carabiners these work well. I have some rep ones that are very similar and I have some rogue ones that feel very heavy duty but again bang for the buck these are good.

These are cool and do what they are supposed to do. If you like the idea of drop sets these work well for your weight stack machines.

So I felt these were necessary upgrade to really give you enough weight for the bowflex revolution. Pretty pricey upgrade. Overall this worked well and gives you up to 600lbs for leg press. You can see the storage worked well as a place for all the "weight plates" to live.
