Manufactured from 80A durometer grey polyurethane with a black anodized 6061-T6 aluminum sleeve, the bushing provides a more controlled connection between the rear differential and chassis while reducing unwanted differential movement under load.\u003c\/p\u003e \u003cp\u003eDesigned as a direct-fit replacement for the factory rear bushing, MMR55-1603 installs into the existing differential mounting location without cutting, drilling, or permanent modification. The firmer polyurethane construction provides increased differential control while maintaining a minimal increase in noise, vibration, and harshness (NVH), making it suitable for both street and track-driven F8X and G8X applications.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSecond Rear Differential Mounting Point:\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eA second MMR55-1603 bushing can be used when adding an MMX Dual Differential Mount, which adds a second rear differential mounting point.
