Yes, there is more wheelhop because of the shackle flip compared to a spring lift due to the fact that the springs have a softer rate.
No matter what, it is less than a lift block.
I noticed a miniscule difference with wheelhop with open differentials because the one tire would just spin.
Now that I have a locker I have wicked wheelhop, which I'd still have with a spring lift. The ride is the same in the rear which is nice. I'm talking about the kind of wheelhop that makes the whole truck shudder, cleans the [bleep] off the seat, and leaves chatter marks on the asphalt.
