That design can't pull the washers through like other designs have.   The support is in the direction of load.

Thanks guys.  Mazda had the diff stub axles aligned ~1/2" forward of the hubs.  We're basically attempting to mimic the position of the OEM diff as closely as we can.  We talked about pros/cons of the sandwich style rear mount and decided that it was more important to maintain geometry and use of the OEM rear bushing than minor downsides associated with requiring users to remove the cover once.  We don't think we have cause for leak concern as you'll basically just butter up both sides of the sandwich with high temp gasket maker.  The welding that occurs on this piece is far enough outboard that deformation should not be an issue.

This also may give folks greater flexibility if they want to run different aftermarket covers.  It'll drive us to a bigger box for shipping so that might change but that's about it for obvious downsides that we can tell. 

Question for the forum...  Since we don't have any welding required should we powdercoat these for folks?

Could this be used with a Cobra diff with some sort of spacers?

The front mounts use a different spread. But you could buy a case for pretty cheap. Just swap the internals over.

Rear mounting should be fine (albeit you'll need to cut the cobra cover or get a new one).  Front mount might be challenging.  It might not be terrible, but I know the spacing of the front mounts is different so spacers won't be trivial either.  I seem to recall that the halfshaft splines at the tripod bearing were different between Cobra and Explorer but if you have some Cobra bits handy we can verify that since I know what the Explorer is.

Short version: anything can be made to work with enough fab, just depends if you want to undertake it. 
My advice: sell your Cobra parts at a profit and then run Explorer.

Definitely interested.  4.10 gears are too short for me - the ratios on the 8.8 are way more reasonable.  Is this going to be like the FC kit and the only part of the halfshaft included is the axle bar itself?  Or is it everything except the outer, Mazda CV?  I wasn't clear about that after reading the first post.

There are a few diffs for sale on ebay, but nothing I saw with halfshafts.  Seems like buying local is going to be cheaper.

Is the driveshaft for the FD diff longer than the one needed for the 8.8?  Might be cheaper/faster to have a local place weld on a new flange to mate with the 8.8.

That's what I thought.  Just needed confirmation.   :)


And this sounds great.  How is there no welding required?

It attaches with bolts to factory holes, hence no welding.   :secret:   

Note, these are welded parts, but all welding is done before it gets to you (unlike our FC kit where you have to weld a piece or pieces to the subframe).

Ahhhhh there it is. Makes sense now. You could try partnering with Jose on in musing power flex bushings in with the whole thing. Just a thought.

Powder coating them would sweet.

Will the drive-shaft need to be longer or shorter?
