On quadratec.com what is the difference between the 2 heavy duty leaf springs? What does (LK) mean?

84-01 Heavy Duty 4 leaf
84-01 Heavy Duty (LK) 4 leaf

I believe the HD is 7" arch and will net you 1" over stock height. I believe the regular duty is 5-1/2" arch and light duty is 4-1/2" arch. Don't quote me on that. I have a saggy 99 cherokee and just purchased the HDs with new poly bushings and u-bolts. I have hit everything with justice brothers for the last few days and I was able to break loose the front bolts which made me happy! The springs aren't here yet. I also purchased OME shocks that I plan to throw on at same time. If you search you will find tons of information. I encourage searching so you don't make a rush decision. Many times after I post I search older threads and either answer my own questions or decide to take another route. Good luck.
