Upcountry package is a 1" taller factory lift, skidplates for the front, transmission/transfer case and gas tank. Also tow hooks front, this one has a tow hitch and Limited Slip axle with 3.73 gears. I'm currently rolling on 31" tires. This has been a solid rig since I bought it used. I have added a 2" lift (about 3" over a stock ZJ) and noticed my milega has come down a bit. Not surprised. But the truck is used freequently offroad, so the clearance is needed...
First mod was the gray matter between my ears.
Synthetic oil in the crankcase, 10W30. Motor has over 156,000 miles on it and this is about as thin as I will put in. Synthetic in the transfer case. Tire pressures higher than I've been using...
Synthetics for the tranmission and differentials. Removing roofrack crossbars.
Play more with tire pressures.
Clean up/smooth underside of Jeep for aero and offroad clearance.
Front bumper, to be solid, yet help with aero if possible, just don't want to make it WORSE!
