Dannopower Donating Members 421 Member For: 20y 6d Gender: Male Location: Canberra ACT Posted 19/02/06 01:10 PM Share Posted 19/02/06 01:10 PM well, my Auto is being rebuilt as we sit here, the next weak link will more than likely be the diff. If I can bust the Planetary's in the auto then the diff shouldnt be a challenge for me! What is the best way to upgrade? Do the internals of the ute diff match the sedan?Anyone blew up a ute diff? Or any XR6T diff for that matter! Link to comment https://www.fordxr6turbo.com/forum/topic/23508-diffs-how-to-toughen-em/ Share on other sites More sharing options...

I run way over 300rwkw and have done for 18 months. I have broken the auto 4 times but never the diff and that includes drag race launching stalled up at Calder and Heathcote. I think you will be ok in the diff department. Link to comment https://www.fordxr6turbo.com/forum/topic/23508-diffs-how-to-toughen-em/#findComment-350763 Share on other sites More sharing options...

I've got over 300 rwkw and no dramas using street tyres.I was always considering a tough 9" rear if it ever let go....But probably not essential to do immediately.That's good feedback deano.... I have been holding off using stickier rubber at the strip, but with positive feedback like that, looks like that might change.I haven't heard of any ute diffs in XR6 "T"'s blown yet....Are there any?tom Link to comment https://www.fordxr6turbo.com/forum/topic/23508-diffs-how-to-toughen-em/#findComment-350773 Share on other sites More sharing options...

LukeCheers Luke.Seems my diff will be fine! As for my trans its an 10/04 build, but the planetarys are being replaced anyway, since I broke 2 teeth off them completely. My doughnut coupling is ok, have checked already.So the CV's in the driveshaft will be the next to go I guess!

It seems the diffs on the Utes are a lot stronger, then sedans?But saying that, my mate has gone through three diffs in his XR8, but there must have been a bad batch of them? If your diff hasn’t blown yet, I would say it would be fine!micksta Link to comment https://www.fordxr6turbo.com/forum/topic/23508-diffs-how-to-toughen-em/#findComment-351038 Share on other sites More sharing options...
kawerx TerriGhia Donating Members 206 Member For: 19y 4m 21d Posted 20/02/06 10:19 AM Share Posted 20/02/06 10:19 AM I believe if you have 3.45 ratio its the older diff set up. if you have 3.46 ratio its the newer stronger diff.I think the internals are a little bigger.kaaz make a tuff diff centre that is popular in motorsport like curciut racing.
