Product Details

This Whiteline Front Lower Radius Arm Bushing fits the 2018 BMW 318i 3 Series. Placement: front. Order it as part number KCA430. Whiteline's note for this fit: Adds +/- 0.5 degrees Caster. The chassis code on the listing is F30. In the box: 2 bushings and 2 tubes.

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.

Installation is rated moderate, with about 3 hours of work listed. Get the car aligned once it is back on the ground. Working on the same car? We also list Adjustable Rear Sway Bar Link and Front Sway Bar Link Assembly for the 318i 3 Series.

Features

  • Caster: Adds caster for steadier steering and better tire contact in roll.
  • Install guide: An install guide comes in the box.
  • Material: Built from polyurethane.
  • Self-lubricating: Built-in grease reservoirs provide continual lubrication and reduce friction.
  • Bushing compound: A synthetic elastomer compound resists oil, grease, ozone, and weathering.
  • Corrosion protection: Metal parts are plated to resist rust over the long term.
