Whiteline Rear Differential Mount Insert Bushing Kit for Select BMW 1991-2000 (318i/325i/328i/M3) - KDT969

Fits select 1991-2000 BMW 3-Series and M3 (318i, 318is, 318ti, 323Ci, 323i, 323is, 325i, 325is, 325iX, 328Ci, 328i, 328is, and M3).

The Whiteline KDT969 Rear Differential Mount Insert Bushing Kit is engineered to fill the voids of the factory differential mounting bushings. By reducing excessive movement of the differential housing, this kit improves power delivery and provides a more connected drivetrain feel under acceleration and gear changes. These inserts are designed for the enthusiast looking to tighten up the rear end without the harshness of a complete solid bushing swap.

Constructed from a high-grade synthetic elastomer, these inserts offer superior resistance to oil, grease, ozone, and extreme weather conditions. The metal components feature a protective plating that acts as a durable skin, outperforming standard paint to resist corrosion in harsh undercar environments. Precision-placed dampening voids are integrated into the design to manage NVH (noise, vibration, and harshness), ensuring that performance gains do not come at the cost of drivability.
