The CJ was produced for a long time. The different number after it does not reflect the components like the new JK does (Sahara, Rubicon, and X). The number is simply just the model name. I do believe.
The tranny in manual Cherokees suck. Hard to find parts for, and the auto is stronger as well
There is only one real true off-road jeep in their new line-up. The JK. 2 or 4 door, still same truck, the 4 door just has a little longer wheelbase. Actually, my parents just bought a new Liberty, and although it is a Jeep, it will see more pavement than dirt, and might I add, it's fuckin' nice, lol. Most of Jeeps vehicles aren't real off-road vehicles though. Mind you, ever since they added an SUV to their line-up (the Cherokee), there has only been one real true off-road vehicle, but the cherokee is kick ass if modded properly, and also goes pretty good in the bush stock. And the Compass is gross. Even if it is a Jeep, I hate it.
Your buddy is kinda a little stupid (no offence) for putting a supercharger on the 4 banger in the YJ. The 4 bangers in Jeeps were/are shit. It is no better on gas, and, less torque (biggie for wheelin) and less HP. My personal opinion, I would have just bought another YJ with the 4.0L. And even if he supercharged the 4.0L I6, by the time he's done with it, it would have cost the same to just drop in a small block.
One more thing, is the ARB locker for the front or rear? Is it the ARB air locker? If so, get it if it is for the front, it's always great to have a selectable locker in the front (one is in my future too), but, if it is going in the rear, don't get it. Get a Detroit Locker. Much stronger for the rear end sinch that's where most of your power is going.
And, since I've moved out and going to College now, my Dad has a bit more money he can spend, he's looking at buying a jeep specifically for wheelin'. I'm so stoked if he does, ooo I can't wait!
I'm glad you don't hate Jeeps, if you did, I would have to hate Toyota's. There are two brands of vehicles I hate though. 1) Suzuki (Samurai's and Sidekicks). Have you ever tried to keep up with one on a trail? Impossible 'cause they're so damn small. 2) Fords, 'cause, well, they're Fords. Haha
