This complete mounting solution for the rear differential features polyurethane construction, replaces all 3 factory mounts and adds the 4th mount that Hyundai forgot to give us. As we all know the stock rubber mounts are very soft. This product is a direct fit for the stock mounts and provides superior mounting for the differential housing. Polyurethane construction provides near solid mounting while providing just enough cushion to reduce parts from breaking under aggressive driving conditions. You will notice some additional noise and vibration but the trade off will be well worth it. After installing you will have better power transfer to the rear of the car during acceleration, improved throttle transition, and a much more stable rear end. All of this contributes to a better high performance driving experience.
NOTE: 4th Mount requires enlarging mounting hole on 2013+ subframe. Optional stepped drill bit available for easy installation. (+$20)

I RECENTLY BUSTED THE REAR MOUNT ON MY DIFF SO I WAS LEFT WITH NO OTHER CHOICE BUT TO GO AHEAD AND REPLACE ALL OF THEM, AFTER A LITTLE RESEARCH I DECIDED TO GO WITH THE BEYOND REDLINE KIT AS I HAD READ THE SOLID ALUMINUM MOUNTS THAT ARE AVAILABLE HAVE BEEN CRACKING PEOPLES SUBFRAMES. I THINK I MADE THE RIGHT CHOICE, MY DRIVE LINE SLACK/LASH IS ALL BUT GONE. STARTING FROM A STOP AND 1ST TO 2ND ARE SO MUCH BETTER AND MORE SOLID FEELING. THE TRADE OFF IS NOISE- BUT IT DOESNT BOTHER ME PERSONALLY AS I WANT TO COMPLETELY BUILD THIS CAR SO THE FACT THAT I CAN HEAR MY DIFF WHILE IM DECELERATING IS PRETTY COOL I THINK. ITS BEEN ON A WEEK BUT SO FAR GREAT PRODUCT, IM VERY HAPPY WITH MY PURCHASE
The difference is crazy like the title implies. It stiffens up the rear differential really well. Especially if you have a stage 2+ clutch that terrible feeling you get reversing on the 2010+ Genesis is pretty much gone. Combine this with the trans mount and you'll have a beautiful ride feeling. There is a bit of a whine noise from the diff because of the stiff bushings but it's almost unoticible especially if you have an exhaust. Overall it makes the car feel A LOT more responsive and gets rid of almost all your shakes when accelerating and decelerating. And reversing is now a dream. Also the fitment is nice and percise no issues.
