Leaf Spring Recall and My Leveling Kit

Hello,
I have a question that I can not seem to get a straight answer for. I recently did a levling kit on my 2005 DC TRD off road. It is a spacer front and block rear lift. I went by the dealership yesterday to ask about getting the new leafs (which they said they have in stock). I asked if there would be a difference in the rake and he said he didn't know but didn't think it would be much. I have read that the Leafs are softer and may sag.
What advise to do you all have. Will I notice a difference or am I better off just leaving the original springs (I don't seem to have any problems with them)

I appreciate the help and advice!

 

I got new springs when they did my frame 2mos. ago, the new springs were flat to almost frowning in front of the axle with just an ARE cap on the bed, also road like shit, felt like every bump was on the bumpstops, ended up having to put AAL on to get the rearend to sit right and ride right.

If your good with what you have, I wouldn't change a thing

 

My 2010 rear springs were shot, when I got the replacements. I saw no real improvement in ride or height and minimal improvement in load capacity.
Putting in a Wheelers aal, fixed all 3. My suggestion would be to replace the potentially dangerous 11 year old springs with the free new pack and spend a few bucks for the aal.
