Hey everyone i'm kind of new to this site and i'm probably gonna hit alot of topics that have been hammered. But i'm currently deployed to Iraq and don't have alot of time on the internet. I have a 2002 QC 4.7. And I want to run an electric fan and want to know the best one people have found or used. Also I want to run a LSD and swap gears. This is the info my girlfriend gave me from my glove box. I need some help understanding it. I also think it has a factory LSD and i've heard about the headaches with the C clips so can you swap a factory LSD for an aftermarket?

DJM: Axle front 205 MM HD DMD: Axle ratio 3.55 DRD: Axle rear corporate 9 DSA: Axle anti spin differe Torque converter- lock Transfer case

Also I am planning on running atleast 22's in the summer possibly 24's can someone help me out with a good gear ratio to go to. Pictures of my truck are posted here. http://www.cardomain.com/ride/2973632
Thanks in advance for your help
