Hey guys

I have an xh ute and wanting to do a big power barra setup and all the blah blah blah that goes with it ,however since ive owned the car I would love to do a triangulated four link Setup in the rear. I have the nouse and tools to do the four link but what diff options do I have?? Obviously 9 inch housing comes to mind but is there any other diffs I could use that wouldnt rob as many ponies from the rear tyres? And of course the weight of the 9 inch is over the top

Thanks
