IIRC, the birfield eliminator basically turns your 'yota axle into a Dana 44. They're about equal in strength, so compared to stock birfs, you're fine. However, I think the eliminator requires an odd size axle shaft, so if you break a shaft on the trail, its a bit harder to find a person who may have an extra one, if you don't. Also, I thought the eliminator kit was discontinued?
Don't quote me on this, This is off memory and recollection. I personally haven't done the research, but I know when I go SA, I'm going with the 30s
If you're going to step up to 30spline longs, I'd definitely go that way rather than the eliminator. Check out bobby Long's website, he's got some strength charts that are pretty impressive, and I know a lot of people run them with some good size tires and are very happy with them
