Whiteline Front Lower Radius Arm Bushing for 2017-2018 BMW 340i GT xDrive 3 Series (F30)

For the 2017-2018 BMW 340i GT xDrive 3 Series, Whiteline makes the Front Lower Radius Arm Bushing. Trim named on the listing: xDrive 3 Series. In the box: 2 bushings, 2 tubes, adjusting tool, an install guide, and grease. Application note: Adds +/- 0.5 degrees Caster. Does not Suit xDrive Models. The chassis code on the listing is F30. It goes on the front of the vehicle. The part number is KCA473.

Caster is the forward or backward lean of the steering axis, and more positive caster generally helps stability and steering return. This control arm bushing is made to add positive caster and alter anti-dive geometry, using a bushing swap rather than a major rebuild.

Expect a difficult job of about 3 hours. An alignment is required after installation. Other Whiteline parts we list for the 340i GT: Adjustable Rear Sway Bar Link.
