Changing to 2011 Leaf Springs on my 2005

About a year ago I did the 08+ leaf spring conversion on my truck, with great results. For those of you that have questions about that, here is the install thread from when I did it:

Finally doing my 08 Leaf Spring Conversion

I've been reading some about the improved ride quality of the 2011 leaf springs. Here is an article I found about the 2011's:

First Look: 2011 Ford F-Series Super Duty - PickupTrucks.com Special Reports

In the article it sais:

The suspension has been tuned up, too. The shocks have new internal valve settings and the spring rates have been adjusted for better ride comfort. In 2008, Ford introduced its 3-plus-1 spring pack for both the diesel and gas trucks but the 2011 model SD pickups with diesel engines are setup with a new 2-plus-1 kit. Brewer said the 2-plus-1 setup reduces some of the spring binding from friction that drivers felt as a secondary impact after hitting road bumps. It also saves weight for improved fuel economy.

I've been looking for a set, and finally came across a deal on a set to try out. Found a 2011 F250 with very low miles, that had a dash fire.





Got them in today. There is definitely a weight difference. The 2011's have 3 leafs where the 2008's I have are 4-leafs each. Here are a couple of pics of the 2011 springs after UPS dropped them off today:





Will probably be the weekend before I get them switched out, but I'll update when I do.

The 08 springs need new bushings on the front end. I had to grind them down when working on getting the hangers made. Ill sell them, but shipping sucks. They are like 68" long and about 100# each!!

Well as another member (new2deisel) pointed out, the UBolt setup on the 2011's is different. The UBolts point down instead of up. Here is a picture of the new UBolt/Block setup on the 2011 springs.:





In this one you can see the plate that goes on top of the leaf springs that has the seats for the UBolts to sit in:

TX, i have mine as well but have to find time to put them in. the yellow stripe, does it go to the front or rear? the dealer doesn't know and i cant just go look at one on the lot. also, i am going to be running the king shocks with compression adjuster. have you had any luck finding results on the fox's you wanted? i know you put bilsteins in and so did i but i am not liking the ride too much. maybe with the new springs they will be better matched.
thanks
