Product review (2 stars): Waste of my time, repairing LFX25973SB
If you have the LG LFX25973SB, this spring will not fit.  It is larger than the original and mullion will not "open" to be flush with the left door, so you will HAVE TO close the left door first, every time.  It's too bad that they list this refrigerator as being 1 that this spring will fit.  I wasted a lot of time with this.
