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.
Standard 10.9 Steel: Equivalent to the OEM fastener strength
Upgraded 12.9 Steel: Heavy duty cap screw fastener with higher tensile strength
Upgraded 4340 Chromoly: Custom made 12 point fastener with the highest tensile strength
Standard style 4th mount installs without modifications on most 2010-2012 model year vehicles. 2013-2106 vehicles will need the hole in the frame opened up by a small amount. Optional stepped drill bit is available to make this installation process easy. Optional reinforced 4th mount includes custom machined steel inserts that are used to sandwich the thin sheet metal sub-frame and adds substantial strength to the mounting location.
