Mopar XJ Stroker
Last year at Moab, Mopar teased us with a 4.7-liter I-6 in an otherwise stock Cherokee XJ. The story was the powerplant would undergo durability testing and might be available later on. This year, the Mopar team is back with the proven engine in the same 2001 XJ, now extensively modified. Word is that a bolt-in long block is now available through Mopar Performance and that the parts include roller rockers, hypereutectic pistons, and oversize valves. Which means any of the vehicles originally offered with the 4.0 six--XJ, TJ, YJ, and others--can be hot rodded with the new long-stroke powerplant, which yields 290 pound-feet of torque at 4000 rpm.
The XJ now offers a completely different level of capability, with a four-inch coil spring lift, tube doors, and custom rock rails. Mopar XJ front and rear bumpers provide protection and add clearance; The front bumper houses a Warn winch. Tires are 33-inch Goodyear M/Ts on AEV wheels.
