Product Details
Fitted to the 2014-2016 BMW 428i 4 Series (F32/F33): the Whiteline Front Lower Radius Arm Bushing (Double Offset). Position: front. Whiteline part number: KCA473. Included: 2 bushings, 2 tubes, adjusting tool, an install guide, and grease. Application note: 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. Get the car aligned once it is back on the ground. To go with it on the 428i 4 Series, see Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Front Sway Bar Link Assembly.
Features
- Bushing material: Polyurethane bushings flex far less than rubber ones.
- Install guide: Instructions for fitting are packed in the box.
- Corrosion protection: Rust protection comes from plating on the metal parts.
- Self-lubricating: Built-in grease reservoirs provide continual lubrication and reduce friction.
- Compliance voids: Voids molded into the bushing allow suspension articulation and soften sharp road inputs.
- Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
