I am currently running AAL's on my 4WD '96 T. I needed to increase my load capacity and compensate for limp OEM leaf springs. The AAL's lifted the rear about an inch and gave me additional 500 lbs. of payload. The ride is just a little stiffer. I have sice added Air-Lift springs because the AAL's could not handle 2000 pounds in the bed alone. I hope to someday replace the AAL's and the OEM springs with a HD leaf pack, I will retain the Air-Lift springs - they are sweet.
