As far as A-Trac goes, doesn't it only work when 4lo is engaged?
That is correct...
In H4 you have TRAC and that is awesome in high range... A-TRAC is the Low Range traction control and it does brake harder any loose tire for über traction control, like lockers provide.
To the OP: If you are going for front and rear lockers, then make sure they are selectable so you can turn them off for steering. The A-TRAC automatically locks/ unlocks loose tires so steering isn't affected, but because of that it makes quite a bit of noise when operating (only when there is slippage, not all the time it is activated).
As much of a fan of A-TRAC that I am, I see no reason (at all) for doing this if it were possible. The after-market lockers you say you are going to get, will get you everywhere.
You could have saved a fortune buying an Off Road as it has the rear locker and A-TRAC. But, if you had to have the longer bed and didn't want the bed extender, I see why the Sport... But surely not for the fake hood scoop and colored bumpers?
If you succeed in installing the A-TRAC, then there is no need for the after-market lockers. A-TRAC provides the traction of lockers, but it makes noise... and isn't "smooth", which seems to bother some here who have front lockers.
I kind of think changing your differentials will be easier than adding A-TRAC to a Sport... But, I would be curious to follow you on this. Maybe search to find if anyone in Japan or anywhere has done it already?
