I'm tossing around the idea of adding a leaf to my truck. I've looked around online and their are several brands and options. I'm looking for reviews from people who have actually added a leaf, or have ridden in a truck with one. My current setup has a 2.5" A/S level, and the front sits just slightly higher.

 

I am removing mine shortly to add airbags. THe AAL does exactly what it supoosed to, but makes the ride a lil stiffer. I came across a smoking deal on airbags so i jumped on them.

 

Did you notice more rear wheel hop over bumps, or it was more jarring, when you added it, due to it being stiffer?

 

I have the long AAL and did not notice much of a difference in the ride after install. I do have a fiberglass cover weighing things down back there so that could make a difference. But it does not ride bad at all.

 

I see you have the superlift AAL, I don't see a long version made by them, you must have the short leaf?

 

No mine is the long. Got it from 4 wheel parts on clearance so maybe they were discontinued? But all of them are basically the same other than the length.

 

OK, good information! I have just read that the shorter leaf gives a stiffer ride than the longer leaf. Maybe some others will chime in as well. Thanks!

 

Yeah the short ones are supposed to be stiffer. However I think they are a bit easier on the install.

 

I installed a long aal in my truck and i cant feel difference

 

Had both 2" aal did not like! stiff ride, wash board over bumps, pain in a$$ to install! Air bags love nice ride, no more body roll, easy to install!

 

I installed the pro comp add a leafs in my truck a found the rise a little stiffer but not much and gave the truck 2.5" of lift and its not that had to install, just get new u bolts made if you install the leafs

 

i didnt really notice any difference really with my AS AAL. Wasnt really that difficult to install either, first side was the learning side and then you fly through the second side. Pretty cheap too...

 

I am in the same boat with a 2" AS leveling kit on a 2009 4x4 KR SCREW. With the rear only 1/2" lower, I don't want to replace my factory lift block with 3" lift block because that will put a 1.5" rake back in. If I wanted a rake, I wouldn't have leveled the truck. I know of two low-cost options.

1. Put in a 1" lift block on top of the stock block. This will give a 1/2" rake. Some will say that this is not safe, some will say it is. I have looked at it and determined that it is not a problem. I wouldn't stack 3" blocks, but a 1" on top of the stock 1.5" seems fine to me.

2. Put a short (6") piece of 1/2" thick spring steel on the bottom of the spring pack - bolted to the pack just like another spring (no one makes a 1/2" lift block as far as I can tell). Similar to the add a leaf except it won't affect the ride or load capability - it will go below the factory helper instead of above it. AS is shipping these to me right now with the longer bolts needed to bolt them to the pack. ($30). This should make my truck sit dead level.

I know that some won't understand why one may bother to add only 1/2", but I just want a level truck.

Since I mentioned load capacity - a quick thought here. Neither rear air-bags nor add-a-leaf kits will add load capacity to my truck. The ford 9.75" rear is factory rated at 4000 lbs (engineers will say it can handle 4500 lbs). The rear of my truck weighs 2800 lbs with just me in it, leaving 1700 lbs of load capacity (650 lbs over GVWR). The stock springs seem fine with this load - I think the axle tubes are the weak link in the chain, not the springs.
