I got an Eaton LSD for my 26 spline '96 Kia for 450 about 3 years ago. The truth is that it works really nice. I don't know how many splines in the front diff, but a limited slip for the front would really add a lot of traction to the very capable Sportage. I've been thinking about bikini doors and bikini rear latch, that would really take a lot of weight off the truck. My only worry is safety on the HY and noise from high speeds. But it would really add to the off road capability.
