Whoa! I feel something burning!!! <img src="/forums/images/graemlins/butwiggle.gif" alt="" /> Did someone mention "lockers"?!? <img src="/forums/images/graemlins/notooth.gif" alt="" />

Here are the options that I know of for the Sportage...

Front differential:

Any differential spec'd for the Mazda Miata ('94-05) and RX7 ('86-91, 2nd gen/non-turbo with the big axles - 26 splines X 27mm). This includes any Mazda or aftermarket differentials (Kaiser, Quaife, Kaiser (as noted) and the OBX Racing helical/torsen-type sold on eBay. They all use 7" ring gears. So they only work in the front - THEY WILL NOT WORK IN THE REAR AXLE!!!! So don't even bother trying... <img src="/forums/images/graemlins/shiner.gif" alt="" />

Rear differential:

The options are very limited. You can go with a clutch-type LSD from a donor-Sportage or see if you can find one of the discontinued-LSDs from Eaton (check out eBay).

Kaiser does not make a locker for the rear axle. I had some dialogue with them on the topic, trying to get them to prototype a 7.5" ring gear mount (their diffs bolt the carrier ends onto a cylindrical housing, so it would only be a matter of replacing the 7" mounting flange). Unfortunately, they did not have any Kia lockers in stock and will not be producing them until they had 10 units pre-ordered. To sum it up, they weren't really interested.

The only other option, which I believe is the best if you're going to be 4-wheelin, is the Lock Right-style locker from Track Finder. Hadtomer has one in his ride and has posted some impressive demo videos of it in action. However, he lives in Israel and was able to source the part from South Korea. Nobody in the U.S. has one (that I know of). And nobody has had any luck communicating with the known-contacts in Israel, or South Korea, for that matter. I've been actively-working on solving that problem. I have found a seller on eBay that is based in South Korea. I have worked out a deal with him to buy the part for $600 USD. I'm just waiting for six Benjamins to accumulate in my pocket so I can execute the purchase. That should happen before the end of February. I will absolutely let everyone know how it works out (both the purchase-process and the install of the Track Finder locker, assuming the deal goes through without a hitch). Once I have the part, I will also pass on the contact info for the seller. I'm holding off on that because I don't want anyone to jump on it and get screwed ("Hey! You said this guy was reliable!!!" <img src="/forums/images/graemlins/scared.gif" alt="" />)... not because I want to be the first kid on my block with a rear locker.

Anyhoo, I know people are going to grumble at the thought of $600 USD for a locker that can be purchased in Korea for $410 USD, which is on-par with the price for a Lock Right-brand locker sold in the U.S. However, as stated before, nobody has been able to get one shipped into the U.S. And I'm willing to pay the extra $$$ to get the best-option differential for my rig. On that note, a new Eaton LSD sells for $599 USD on eBay and the Kaiser lockers for the front axle sell for over $700 USD. Kaiser is not an option for the rear diff. Also, clutch-LSDs require synthetic diff oil (not a major issue) and clutches wear out... and you can't find replacement clutch packs for them (major issue). You might find a used clutch-LSD on a donor-Sportage for less. But the clutch pack has miles on it. How many miles are left??? Who knows - but I sure as <img src="/forums/images/graemlins/ignore.gif" alt="" /> don't want to find out on a remote trail... <img src="/forums/images/graemlins/zombie.gif" alt="" /> <img src="/forums/images/graemlins/zombie.gif" alt="" /> <img src="/forums/images/graemlins/zombie.gif" alt="" /> Yeah, so it's go big <img src="/forums/images/graemlins/evil.gif" alt="" />... or go home... <img src="/forums/images/graemlins/baby.gif" alt="" />
