It replaces the factory rear differential mounting bush and can be installed at either the factory differential height or a +10mm raised position, so the same part serves both standard-height and lowered G8X cars.\u003c\/p\u003e\n\u003cp\u003eAt OEM height the polyurethane bush gives the rear differential a firmer connection to the chassis, reducing unwanted differential movement under acceleration and changing drivetrain loads with minimal added NVH. On lowered cars the +10mm position raises the rear mounting point to restore driveshaft geometry, which cuts operating angle, heat buildup and premature wear on the axle shafts and CV joints. It installs into the factory mounting location without modification, works with OEM and aftermarket axle shafts, and suits road and track use.\u003c\/p\u003e\n\u003cp\u003eThe bush is part of the MMX G8X differential mounting system.
