The price looks awesome, BUT buyer beware of what you are getting. I just ordered a pair of LBJ's and outer tie-rod ends from Toyota and the OEM LBJ's are $89 each and the OTR's are $48 each, so for OEM that is $275 for just those 4 components.
With all the reading about LBJ failures and such, I would be leery of complete kit that cost less than just the two LBJ's. I may be a bit of a parts snob and I will admit that I am partial to OEM on most of the things I replace, but at that price, all I will say it the quality of the components is going to have to be relatively low. I mean even the cheapest LBJ I found at NAPA was $61, so for 2 would be $120.
If you want to give it a try, that is your option, but I would not use it on my rig. Just my $0.02
Also, Toyota stopped selling the Upper ball joints individually, they only sell the complete knuckle now. It had to do with the liability of trying to press the joints in and out correctly. If they are installed incorrectly in can cause improper stresses on the joint and knuckle, potential for bad JU JU.
