Product Details

This Whiteline Front Lower Radius Arm Bushing (Double Offset) fits the 2017-2020 BMW 440i 4 Series. The chassis code on the listing is F32/F33. Application note: Adds +/- 0.5 degrees Caster. Does not Suit xDrive Models. Position: front. Whiteline part number: KCA473. Included: 2 bushings, 2 tubes, adjusting tool, an install guide, and grease.

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. Working on the same car? We also list Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Front Sway Bar Link Assembly for the 440i 4 Series.

Features

  • Grease: Supplied with molybdenum disulfide grease for extended service life.
  • Bushing material: Made of polyurethane, which resists deflection better than soft rubber.
  • Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
  • Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
  • Compliance voids: Voids molded into the bushing allow suspension articulation and soften sharp road inputs.
  • Corrosion protection: Rust protection comes from plating on the metal parts.
