The ARB is actually a torsion bar which is designed to twist along its length so it adds additional spring force to the suspension under cornering. A solid section will reduce its ability to twist, effectively making it stiffer. By having the disconnect in the middle the two sides will have a different amount of 'twist' although both sides should still be twisting so maybe it will be the same amount for both sides. I will be interested to hear how the difference caused by the disconnect affects the handling, theoretically it would give more oversteer.

If it suddenly breaks, go back to the last thing that you did before it broke and start looking there

Looking at the photo, the actual torsion bar is equal length each side, (and very short).
I imagine that the large diameter tube has a pivot axle along the centreline, an arm on each half of the tube can be pegged together, then the two piece tube becomes one solid bar.
The weld/crimp whatever marks look the same distance from the ends of each torsion bar.
Don't know why the large tubes are unequal length, must be to clear the drag link or steering damper when fitted.

Hmmm... I'll report back when it's fitted and road tested...
Last time we went 'laning with Rus from JImnyBits he was running one on his own Jimny and was very happy with it...
Yes, from what I remember of the instructions the original ARB is cut exactly in half, the tube dsconnect system is then welded over it, so in the photo the stub of one half is under the grease nipple you can see on the top...

the ARB is cut directly in the middle so one end slides into the other, so when bolted together acts the same as the original bar, as there is nowhere for the bar to go
ive tested this on both a standard jimny and modd'ed fully loaded jimny and it makes no difference in handling as it wont, ive even turned flat one way at 30 in the modded jimny ..... lots to tyre screeching as you would expect! but all is well
