I just picked up my Suburban Its a 95, 2 wd, 2500, 5.7 mtr, 4L80E trans. Its a no frills truck first bought by the New York Power Authority, they had it for 10 years. Total miles are 64,000. New tires (firestones) and new battery. Paint is very good , just a little rust on the bottom of the barn doors. I'm going to change the serpentine belt. Flush the antifreeze, and replace all the hoses. I'm going to get the trans flushed and install a deep pan and a shift kit. I plan to use synthetic fluid in the engine, trans and rear gears. I'm going to tow my race car trailer (26 ft enclosed)with this. Do I need to do anything to the suspension? I be using a weight distributing hitch and anti sway control. Any other suggestions???
