Was nervous about the install on my 4000 series rack, but the brackets lined up perfectly and it took about an hour. The weight stack itself feels rock solid with zero clanking, and switching pins mid-set is way faster than messing with plates.

The stack glides so smoothly it honestly makes my old plate changes feel prehistoric. Setup took a bit of patience with the rack rails, but the resistance curve is buttery and the drop-in fit for my 5000 series was spot on.

Installed the weight stack upgrade this weekend and was surprised how smoothly it glides compared to the old setup. The selector pin feels solid and clicks into place exactly where I need it. Really glad I went with this instead of trying to rig something myself.
