Haven't gone that route yet, still need to get a good measurement on level ground in garage.. plan on putting on the dual steering stabilizer end of next week, so will be getting truck into garage to get a good set of numbers. I may just leave it at the current rake since it does not look too bad. Once I get the rear wheel well liners, it will make it less noticeable as well

I think you can use the SRW 2X4 air bag kit from AirLift if you lower the SRW 4x4. The way the lower part of the bags mount is different between the 2x4 and 4x4 kit.

I have the 4x4 AirLift 5000 installed and hope to use the Ford parts to lower the rear (6C3Z-5598-A spacers, and BC3Z-5705-C u-bolts). And then just replace the lower part of the AirLift bags (I spoke with AirLift and have ID'd the parts to change). Now I just need some time to get this done.

Whats the 5er length, height, weight, and hitch pin weight?

Please correct me if I am wrong but this makes no sense to me.
Wouldn't the distance stay the same since you are changing the height below the tang?

Sooner in TN - I also originally installed the 1.5" PMF blocks with bump stop but without the airbag support. 1000 miles from home I hit a dip in the road and bent the bump stop tang on the PMF block. It's not strong enough to support the airbag. I ended up removing them and going with the PMF blocks with airbag supports.

Thanks. Looks like the PMF support isnt just connect to the block, but has a price that sits on the axle?

If you run the firestone bags you dont have to worry about the tang. The bag ride on the spring and the bump stop stays factory.

1.5" PMF blocks

I think that’s just for 2wd that mount on springs? When I look at the firestone bags for 4wd, they include a tang saddle

Yeh that might be. I have the plain jane B&W rail system installed, hence the reason for the airbags
