Anybody know if there is a quick disconnect aftermarket mod for the WK2 to enable better articulation off road? Or if there are away bars of a more moderate length allowing more wheel travel?
Unfortunately for the folks that want to use the WK2 for "hard core" off road, it has become softer than the WK which is softer than the solid axle WJ that preceded it which is softer than ... making it a heck of a challenge for rock climbers. Those of us that do a lot of highway cruising and need something that handles severe weather and can tow a decent load without breaking a sweat are not complaining.
The WK2 is not going to articulate, not enough rebound... lots of other issues and road blocks in the way. Nothing more than relatively short lift kits are available (lifts to about the same height as the QL), and a few decent tires. Useful articulation will require ripping the body off the OEM suspension and shoving something else under it, what someone may do someday. Now if you can get by with two or three wheels on the ground grabbing traction, it is not a problem... but I think the WK2 components may be too weak to take much abuse. You may find articulation may be overrated in most cases.
As fas as lockers, unlike QDs of the past, the WK2 QD rear is a true locker. The primary purpose of which is to lock the rear when the driver mashes the STR8 throttle (the transfer case also locks). Thats most of what Jeeps means when they say the system anticipates the driver. The older system needed a bit of wheel spin to limit slip, so locking quicker can slice maybe .2 seconds off the 0-60 times... Anyway its a locker that happens to also be useful in severe weather and off road (as long as you don't need much articulation). You just can't manually control it. Jeep engineers found that a front locker or ELSD provided no benefit as the processing power within the new traction control computer and brake traction control can more than make up for the front in severe weather or "mild" off road. No need for 0-60 as there is little weigh on the front when the throttle is mashed. So the WK2 4WD system may be the best ever, but its more of a road/severe weather and tow truck than a challenging trail off road truck.
The way we solved wanting to out an play on the rocks is we throw the old CJ on a trailer and use the WK2 to tow it to trailheads.
Vendors are not interested in making up different WK gears, let alone lockers for us. The old style limited slip gears are too big to fit into the front diff housing, so it would be somewhat difficult machining ($$$) to stuff in. And the rear QD already has a locker. You just can't pull the axles out of a WK2 and shove a ford axle under without a masive amount os rework. The WK2 pumpkins are solidly mounted to the frame, not floating with the axle... and the axle shafts are short... plenty of challenges.
