PORC 4.88 gears

Have a d44 to put in the XJ and thought now would be a good time to regear, found these package deals with master install kits and gear for 179.00 per axle from performance offroad center. Anyone have any experince or is this too good of a deal. The plan is also to spool the rear and aussie up front at the same time. It is not a daily driver.

I have ordered a couple of things from them. So far they have done good to me other than it taking a couple of weeks to get my parts. They don't stock stuff in house so it all has to be drop shipped from different places. I have heard good things and bad things about there shipping methods but never anything bad about there products.
