And I just bought the Fenfab stiffy diffy...
How much better is this?

 

[Cruising68]

I've got a Diffy Stiffy not installed yet. But I also have a subframe on order. I'd say this one definitely looks beefier than the Fenfab. It also doesn't look like it has slots on the diff plate. I worry the slots in the diffy stiffy could allow movement under duress. If I were choosing one today instead of a subframe I think it would be this one.

I've made my opinions on the Diffy Stiffy well known on this forum. https://www.explorerst.org/threads/...oom-from-emergency-auto-brake.2148/post-36529

This is a definite step up and yet...
Read the post as to why I find the concept at fault, and then look at this design- BTW, I'm seeing just these pics, so perhaps I'm missing something, but ask yourself these questions. Is it truly limiting z-plane travel? Will a single bolt in the differential cover that's offset to the force be enough? Why Is the rotating motion of the differential in the same plane as the rotation of the 'isolator'? When I look at this design, I see something that would be very good at busting the diff casing around the single bolt during wheel hop.

I can't really say to be honest
The AWR option does not require drilling , it's a direct bolt on
We've also have had test units installed on a few customer ST's that drag race every weekend
It's always great to have options
We've been working with AWR Racing out of California since 2006, their mounts are highly regarded on many platforms. We have a few more parts to release with AWR for the Explorer so stay tuned!

That's my one fear about both products. They are depending on cover bolts and aluminum structure around them that were not likely designed for the stresses that the bolts on top of the diff were designed for. Again though just makes me question why the heck they dropped one of the bolts for the performance model. And also the reason I am forking over to make it correct....at least in my mind

there are 2 diff bolts holding the mount in place

I'm one of the guys that have been testing this AWR brace.

4 weeks of testing at the drag strip prior to public release. 2 test n tune days and 2 legitimate index drag races.

ZFG 93 octane tuned. Whipple intercooled. At least 20 passes down the strip, and uncounted passes in "Mexico" in between. Hard brake boost launching, WOT. No issues.

I doubt you'll see anyone say definitively that one or the other is "better". They both aid in supporting the differential and this brace just gives us, the end users...options.

I'll tell you what sold me on it. Simply put, AWR specializes in engine and chassis mount/support items, meaning they're experts in the field of finding and implementing solutions for these critical type areas. Brett and Fenfab are AMAZING in their own right, and that is unquestionable and undisputed. I have several Fenfab products installed (I even have a diffy stiffy in my garage) on my ST as well and this post should not serve as a negative connotation toward Brett or Fenfab.

I say all of this while NOT being an expert in vehicle dynamics or engineering. I'm just a daily driver and end user. It's up to us as individuals to find solutions that we feel work best for us and our intended use.

what socket/size are those diff bolts? just external torx?

 

[Crisisballer17]

Yes Etorx. It's either E16 or E18, I cannot remember exactly but, I can get you the right answer when I get home from work and check it.

Inverted E18 is the correct size

My initial thoughts on seeing this mount was that it was a huge step in the right direction, but with a single differential mounting point (bolt) where the line of force would be directed towards the thin side of the differential casting, it looked suspect. I looked at all the pictures on your site Ron and couldn't see where the second differential mounting bolt is located. That being said, if it's on the differential on the RH side placed inline with the diff casting in the line of force (thicker up-down), then I'd say this mount looks like money well spent and certainly cheaper than buying the subframe.

If you don't mind me asking, What did the subframe run ya?

here's a pic of the diff plate from another angle

$1400 delivered. Supposedly on it's way. Need to source the bolt and there may be an insulator in there. Assuming I can get those from my local dealer without getting too ripped off.

 

[ron@whooshmotorsports]

Will this fit a 2021 Platinum Explorer 3.0L V6 AWD?

yes it does

Thanks for the pic, that's a part that I would buy myself- if I didn't have a 2020!

Is the included hardware stainless steel?

 

[ron@whooshmotorsports]

of course!

 

[Blown F-150]

Ordered. Hope to get the proper subframe from the dealer for a “permanent” fix, but this seems like a viable stop gap.
