Air bag question

I have a 2015 DCSB Off road and I just ordered a set of Firestone ride rite air bags for it. All other suspension being the same factory installed , will I notice any more excessive rake on my truck? I plan on maintaining 40- 50 pounds of air in them and generally use the truck for highway travel, firewood hauling and minimal trailer towing.

I would like to get a set of 5100's up front with new coils eventually, but not in the near future.

 

After installing mine I keep about 12 to 15 PSI in the bags on a regular basis because I think the truck rides much better. I also have a cap now... There is a noticeable rake but I am in the process of installing the Toytec 1/4 spacer which gives a 1/2 lift to get rid of some of the rake. I know for a fact the Bilstein 5100's are a better choice but I can't justify spending 200 for front shocks and 300 for install on an alignment when I have shop installing the Toytec top spacers for 100 bucks with alignment. I know the stock shocks are not the greatest but I only have 16000 miles on them and they do the trick for what I use my truck for. I know some will crucify me for suggesting a "spacer" but I feel it is a minor change to the geometry and a viable option for conservative Taco owners. I will try to post some before and after shots if you are interested.
