Product Details

This Whiteline Rear Differential Mount Bushing Kit fits the 2011-2016 BMW 550i. The kit contains 3 bushings, 3 tubes, and 3 washers. Placement: rear. Whiteline part number: KDT990.

The differential is hung from the chassis on bushings that are soft for comfort. Under hard acceleration and braking they let it rock, so power reaches the wheels a moment late and the rear end can feel loose. A firmer bushing holds the differential more steadily, which sharpens throttle response. Polyurethane resists deflection far better than the soft rubber it replaces.

Installation is rated difficult, with about 3 hours of work listed. It does not require a wheel alignment.

Features

  • Install guide: An install guide comes in the box.
  • Bushing compound: A synthetic elastomer compound resists oil, grease, ozone, and weathering.
  • Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
