So I want to put a Ford 8.8 under my truck. There are a ton of advantages to these Explorer standbys over a typical 9 inch in many of the earlier cars. The Jeep boys love them for their strength over the Dana 44’s.
They have:
- limited slip differentials
- Are beefy with 3.25 diameter tubes and 31 spline axles(arguably so are 9’s)
- Have a great after market parts selection
- And best of all can be found with disc brakes.
The down falls are:
- The use c clip axles (this can be eliminated if you want/need)
- Have tubes that aren’t welded to the third member… but they can be welded
International trucks have a 1.75″ rear spring which is thin by today’s standards. So the options were to make some funky new spring fit with some customization…. or…. find someone who could make perches. I looked all over on the Internet and didn’t find a 1.75″ wide 3.25″ diameter perch (imagine that). However, a guy on http://www.oldihc.org named Spreader had the perfect solution! It turns out the guys (Kert) at http://www.diy4x.com could make me a set…. luckily all of their tool dies just fit and they turned out great. Check them for your perch needs. Pictures below.
