an option that everyone seems to miss and thats relatively cheap, is the way the americans go, they put the 8.8 irs dif out of a mustang, will take all the power a cossie will throw at it, give loads of ratios to choose from, do a search for xr4ti 8.8 and u will find how to do it, its the way i will go if i ever build a big power sierra

Theres only so much u can do if your after a big power proof diff because the week link is the crown wheel and pinion! You can get a gripper or a quaife but the gripper is better as its a plated diff but is a bit more hardcore!. But there still only a 7.5 inch units both will lock both wheels and give much better grip over the standard one and will be much stronger and harder to brake. But as said the week link will still be the crown wheel and pinion but u can get it shoot peened and super finished to make it stronger or if u have deep pockets get a 9inch diff
