Product Details
Made to fit the 2013-2018 BMW 320i xDrive 3 Series (F30/F31), the Front Lower Radius Arm Bushing from Whiteline. You receive 2 bushings, 2 tubes, adjusting tool, an install guide, and grease. Placement: front. The part number is KCA473. Whiteline's note for this fit: Adds +/- 0.5 degrees Caster. Does not Suit xDrive Models.
This kit does more than replace rubber. Its offset design moves the pivot point of the lower control arm to add positive caster and change how the front end resists dive under braking, which improves straight-line stability and turn-in feel.
Installation is rated difficult, with about 3 hours of work listed. An alignment is required after installation. Other Whiteline parts we list for the 320i xDrive 3 Series: Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Rear Lower Trailing Arm Bushing.
Features
- Grease: Moly grease is supplied to prolong the life of the parts.
- Caster: Caster is optimized for stable steering and good contact through roll.

- Install guide: Step-by-step installation instructions come with it.
- Compliance voids: Voids molded into the bushing allow suspension articulation and soften sharp road inputs.
- Alignment adjustment: Adds adjustment so the alignment can be optimized.
