OK- lets sort things out:

1. My rear locker - from trackfinder- is a FULLY LOCKING DIFF - it is not air operated, not electric- its an automatic kind. if you go to wikipedia- its the first kind:

http://en.wikipedia.org/wiki/Locking_differential

Automatic lockers lock and unlock automatically with no direct input from the driver. Some automatic locking differential designs ensure that engine power is always transmitted to both wheels, regardless of traction conditions, and will "unlock" only when one wheel is required to spin faster than the other during cornering. They will never allow either wheel to spin slower than the differential carrier or axle as a whole, but will permit a wheel to be over-driven faster than the carrier speed. The most common example of this type would be the famous "Detroit Locker," also known as the "Detroit No-Spin," which replaces the entire differential carrier assembly. Others, sometimes referred to as "lunchbox lockers," employ the stock differential carrier and replace only the internal spider gears and shafts with interlocking plates. Both types of automatic lockers will allow for a degree of differential wheel speed while turning corners in conditions of equal traction, but will otherwise lock both axle shafts together when traction conditions demand it.
Pros: Automatic action, no driver interaction necessary, no stopping for (dis-) engagement necessary
Cons: Increased tire wear and noticeable impact on driving behavior. During cornering, the automatic locker is characterized by heavy understeer which transitions instantly to power oversteer when traction is exceeded.
Some other automatic lockers operate as an open differential until wheelspin is encountered and then they lockup. This style generally uses an internal governor to sense a difference in wheel speeds. An example of this would be GM's "Gov-Lok."

2 - modifications ARE available for the sportage - but do not come cheap - if i were living down under- id be very happy with what local firms have to offer - lots of stuff on my rig came from OZ- my LOVELLS coil springs - my old man emu rear tracking arms for instance. right now im saving for some extractors - also from OZ (pricey shipment...).

3 - whatever you cant get down under - you can get from korea -

diff locks - trackfinder

front extended forks ? got them too

4 - cant get the part? get creative !!! no rear springs for big flex? get some tj springs. no re locating the rear panhard mount? do it yourself -

5 - yes - i will admit that modifications for my kia are far mor expensive than modifications for a suzuki - but the kia is kind of special...i like it. people with wranglers are always surprised on the trail - and i LOVE IT!! so im willing to spend more on my hobby.
