I purchased a Jag irs because it was supposed to have a Dana 44 center section,which in 4x4's I've never had a problem. I can't say the same for the 8.8 differential. If I had the bucks,I'd probably get the 9in. center section,but I don't plan on finding one for a 150 bucks like the Jag. It's all a matter of choice and economics, good luck with whatever you use.
