On E36 drift cars, the factory front differential mounting bolt is a common failure point. Repeated shock loads can bend or break the bolt, particularly when worn differential bushings allow excessive movement.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOur 14mm Front Differential Bolt Upgrade addresses this weak point by replacing the smaller factory bolt with a larger M14 bolt. Combined with our rigid UHMW front differential bushing, the upgrade reduces differential movement and provides a stronger mounting connection under load.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe kit uses an OEM BMW grade 10.9 mounting bolt and our precision-machined UHMW bushing.
