As far as longevity with the 4 liter / manual combo, my '94 XJ (Small Bodied Cherokee) is coming close to 300K. I put a clutch in it around 225 K. If you want comfort, and speed, don't even think about a Jeep. The new JK is the most stable platform Jeep has ever had. I helped my friend mildly build his Rubi with 35's, and the stock gears. It feels rock solid in way off camber situations, and during climbs. The articulation is pretty impressive for a basicly stock setup. Leaf springs on a trail rig? puhhleeze..... Give me coils, and long arms any day. They drive it from Southern Illinois, to Moab UT twice a year, and have done most of the trails out there. They actually have some video of them with Dan Mick. Pretty cool stuff.
