Can anyone that has used this FFR rear disc conversion kit on the 1987-1993 Ford 8.8 rear end provide advice on the choice of axles?
I’m am stepping up to 31 spline and sticking with c-clips
I haven’t found the “easy button” on this one.
I looked into Motive which are widely available here but local guys here said don’t touch them, they’re cheap for a reason.
Moser/Strange are extremely expensive to ship to my location but for quality I’m willing to pay for it.
On the Moser & Strange it seems the flange OD is too large for the FFR disc inner hub. Maybe it’s something to do with the fact it’s an ‘94 disc? Along with this it seems that the center hub bore for the “OE” fitment is 64mm as should be expected. The discs from the kit has a bore of 70mm. So I have the LMR spacer rings but was looking to possibly eliminate the need for them.
Do I order the OE fitment style axles in a 31 spline and OE length (my test fit of the kit worked very well on the old 28 spline axles so length is good) and turn down the flange on my lathe and use the LMR spacers?
Is that really the only option?
Any advice on this would be appreciated
