Product Details
This Whiteline Rear Differential Mount Bushing fits the 2017-2020 BMW 430i xDrive 4 Series. Whiteline part number: KDT919. Included: 5 bushings, 3 tubes, 3 washers, an install guide, and grease. Placement: rear.
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.
Whiteline rates the install as difficult and lists about 4 hours. An alignment is required after installation. Other Whiteline parts we list for the 430i xDrive 4 Series: Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Rear Lower Trailing Arm Bushing.
Features
- Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
- Install guide: Step-by-step installation instructions come with it.
- Corrosion protection: The hardware is plated to stand up to road conditions.
- Self-lubricating: Built-in grease reservoirs provide continual lubrication and reduce friction.
- Bushing material: Polyurethane bushings flex far less than rubber ones.
- Grease: Molybdenum disulfide grease is included to help the parts last.
