I have a 02 tahoe that has the 5.3 and had the autoride system on the rear but the compressor went so I just installed some load leveler shocks since I tow a good bit. My concerns are that I just hauled a 2400LBS tractor and double axle trailer that weighs around 1500lbs. The hoe sat real low in the rear and it concerns me cause I have a jeep that I will be towing to trails and it weighs 4500lbs plus the trailer weight. What can be done to help with towing capacity like z71 springs and/or lift? I just would like it to sit more level. Thanks for the input.
