The glide on this thing is buttery smooth, honestly feels like a commercial gym upgrade for my rack. I paired it with the 4000 series and the pin drops are so much quieter than loading plates every set.

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.
