Finally got them installed. I went with the lighter duty ones (I think they are 1000lbs helpers) and I did not install the spacer. On my 4x4 that left me about 5/8" clearance to my axle so they don't affect the ride while driving empty.

Got a chance to load er up good with firewood and she only saga 2" out back now. 39" fender clearance up front and 37" out back. I have a 2" level so I'm happy with this, before my mud flaps would be close to the ground.

Hauling felt great, almost stock like. No sway or porpoising with the help of my bilstein 5100 out back.

Was I over loaded? Maybe close, my payload is 1944lbs and I would guess with me I was right around that.

Earlier I posted about how I went with airbags and quickly got rid of them. I can say I am super happy with these. I still have full articulation, and I don't have to worry about ripping bags off my truck if it goes on a hoist.

 

Looks like you have the black ones which are the 1500lb rated ones, the blue ones are the 1000lb.

I have the 1500lb ones as well, I really like that they rarely engage on normal driving and perform great under load.
