Rear Diff Mount (Apikol) Polyurethane, B6-B7-C6 Chassis

SKU: APK-10A02151

* Required Fields


Apikol has switched to a newer, machined mount as opposed to the old style cast one. So your mount will not look exactly like the picture, it will be machined instead out of a piece of billet aluminum.

As always, JHM tests all the products we sell even if we don't make them in house. This rear diff mount is no exception and performs well. We have noticed cleaner and crisper launches, aggressive upshifts and downshifts

In typical JHM style here are 2 videos of some of the abuse we have put this mount through on our in house 2005 B6 S4.

Just got it installed today on my 04 S4, turned out to be easier to install then what it looked like. Amazing results... the factory one was fine, but the density was horrible from that spongy rubber... I am going to love this mod Review by David (Posted on 11/17/2012)
Great piece, have had it installed since Fall 09. Definitely improves driveability in all situations. Review by Brian (Posted on 4/25/2010)
I installed this on my 04 S4 in about an hour. Very easy install with well documented instructions. Easily a great mod from stock,this diff mount really tightened my driveline up in a major way.Very noticable indeed. My stock unit was like a sponge compared to this very high quality unit. Highly reccomended!! 5 Stars here. Review by brian (Posted on 3/30/2010)
I installed this on my 2004 S4 and what a difference this made! Definitely stiffened up my drive-train. The old mount was in one piece but definitely had a lot of slop. Worth every penny. Review by ray (Posted on 3/27/2010)
2005 B6 S4 - A+ Absolutely Terrific

Fantastic product, makes the shifting feel so much smoother and more positive. It's how it should've felt from the factory. Also shift feel during very aggressive driving is far more predictable.

Excellent product, must have mod.
Review by Brian (Posted on 9/15/2009)
This is a great modification if you like to shift hard and you hear the dreaded rear diff clunk. That clunk is your rear diff slamming on the bottom of the floor board!!! This mount eliminates that clunk. All without compromising NVH. I have absolutely no more NVH than I did previous to the install of this diff mount, but my rear diff never clunks on hard shifting now. Perfect - the way the car should have been released from the factory. Review by David (Posted on 11/17/2008)
