^^ Heads up check the orientation on those Super Pro bushing.. You will want them flipped so flat side matches the diff cover bolts.. The cuped side faces the spare tire compartment..

Either that or I could turn the shaft around. 3 bolt tranny and diff flanges are the same anyway.
Though call.. That may mean more shaft cutting... Which I don't like..

Fun day a head.. Happy modding!!!

both sides of the bushings are
cupped. These are the HIgh Hp version that use spacers on the diff side.
there wouldn’t be any cutting required if I just turn the shaft around, I don’t know, maybe the cv end should really be on the tranny end though, either way it should be fine, bending the linkage isn’t a huge deal.

yeah, I bought these when I had my 2013 years ago and Mike told me recently that they were the High HP version. I don’t really know that there are other versions.

Yes the normal street version look like these on the backside, closer to OEM.

When did you swap in the OS Giken unit into your donor diff.. ?
What was the donor diff out of??

Where you able to pop out the axles all on your own ?? I couldn't do it all by myself.

ahh I see.

I took the one off the car and doing the swap on that.
Yeah the axles popped out pretty easily with a pry bar.

2014 diff I guess doesn’t need to be opened up to fit the OS Giken diff?







This is the snap ring tool I used. Got it through Amazon for like 60 bucks.

Nice. Tons of room there to fit the diff in the housing. Wish it were that easy on an '08!

Well shoot. That makes me hopeful that my 13 is an easy install!

Does anyone know when the diff changed? Is there a part # on your 14 that I can cross reference on my 13?

@Jwconeil The IS F's from 2010 to 2014 came with 3 different Torsen LSD full carrier part numbers..
Your 2013 will be the same found on @JT2MA71 2014.


41110 CARRIER ASSY, DIFFERENTIAL, REAR

1) 41110-53290
*FGR=47:16=2.937
(08/2009 - 09/2011) = MY 2010

2) 41110-53291 *FGR=47:16=2.937
(10/2011 - 04/2012) = MY 2011 - 2012

3) 41110-53292 *FGR=47:16=2.937
(05/2012 - 07/2014) = MY 2012 - 2014
