I ran one on my 87 4runner that I did an SAS on and it is a nice kit. Are you talking about the one from randy's ring and pinion? It uses chromoly axles. The only downside is the price and they are stronger than a stock birfield but not as strong as the longfields. Nice thing about them is that it is so much cleaner than a birfield and very easy to install. Just my 2 cents
