Air Bag Sizing

My 55 Chrysler is very heavy in the front due to the Hemi. I am running Slam Specl. 6" bag right now because of the size required no modification to spring bucket. Well its time to modify. The small bags just dont lift well, I need to be at full 175 lbs in tanks and its a very stiff ride. Can use some help on how to get better lift with low pressure and hopefully a better ride.

 

Call the airbag company!

 

I believe the full size truck guys are using the RE7's in the front.
