Quadratec Leaf Packs - Difference?

I noticed in my Summer issue of the catalog that they have changed the way they list the springs. They now have a HD 5 1/2" Arch, HD 6 1/8", and a 7" arch. On there site they list standard, HD, and HD (LK). All of them say they are 4 leaf packs. The thing is is that the part #'s are goofy. In the catalog they show the smaller arch as a 56010.10 and it goes up to a .12 # for the 7" arch. But on the site it shows the "standard" spring as the .12 #?
Does anyone have any experience ordering these packs sence they changed the way they list them. I called them and the idiot kid in the call center couldn't really awnser my questions.
Thanks!

My guess would be that they are standard, tow package, and Up Country.....but I'm sure if I'm wrong, I'll get corrected immediately....

i noticed the same thing you did and just never got around to calling them!

I dunno what the deal is?

I purchased the HD off the site and they raised the rear 1" to 1.5" over stock.
