Hey Guys....and gals. My '03 Expy has open differentials and I'm very interested in upgrading to either a Eaton Truetrac limited slip or a locker. I've done a bit of research and I'm discovering that not many or anyone offers something for the 9.75 IRS rear end. Evidently the rear drive axles are the type that have a circular spring clip that sits at the end of the shaft which then locks the shaft into place when the clip reaches a slot inside the side gear. Unlike the shafts that have a ring clip that gets inserted at the end of the shaft once the shaft is installed into the differential. ARB supposedly issued a news release saying they offered a locker for the 9.75" 34 spline but come to find out that it's not compatible with the IRS. I talked to an ARB tech rep and he said the side gears would need to get machined for it to work.
For the front, I think it's an 8.8" same as the F150 but not positive. If it is, there'd be more offerings.
Anyone do any upgrades?
Thanks!
Bob
