The kit works. But, the draw backs are parts availability and overall strength. If you go to the eliminator kit and you snap a joint or an axle, where are you going to get a spare? Special order for the axle at least. If you're running longs, you can toss a spare stock axle/birfield assembly back in for the mean time. Cant do that after you've gone eliminator. Just think, after you replace both your working stock axles with the Longfields, you already have spares for both axles and two spare birfs. You put the eliminator kit in, you have to buy MORE parts to get spares.
Imagine yourself stuck on the side of the trail with a snapped eliminator kit and you just need that little bit of 4WD to get you back out. 25 other Toyotas pass with spare stock birfs they're willing to give/sell you, but you cant use a single one because you went with the eliminator kit.
Why even go for the eliminator kit when all it does is make finding parts harder and give you less strength? Go buy some 30 spline Longfields, axles, and hub gears.
