you guys have read my mind, and i dont think there is much on the market for SJ axles...
i thought about using line locks, or there are trailer line locks that exist, that operate electrically, that way you dont have to run hydraulic lines up through your cab
50$ each is what i hear they run for
and i think if i stomp the brake nice and hard, flick the switch to lock the pressure on that wheel, and release, it would work very well

The solinoids your talking about work very well. I installed one on a fork lift and it worked well. Flick a toggle switch and hit your brake pedal to set it. To release turn it off and hit your pedal again. The only problem is for inspection you need a mechanical braking system; aka: parking brake.

why hit the brake again after you release the pressure?
and in my case it would sorta be used as a parking brake if theyre designed to hold pressures for long periods of time, but for most im guessing they would use this along with their mechanical parking brake

oh, and is 50$ cdn pretty accurate for the price of one?

i like this post!! someone reply some more
zuks are cheap, therefore mods should be cheap and innovative, not bought out of catalogs and installed by a hightech offroad shop, atleast half the fun is building

Line Locks aren't that expensive, they are normally used on race cars to lock the front wheels to do a burn out to get the rear tires hot.  Here is Jegs selection

I've been eyeballing the racing line locks as an alternative to the Pork-barrell unit which works very well I might add.  Just very expensive!!
