Product Details
Whiteline built the Front Lower Radius Arm Bushing (Double Offset) for the 2017-2020 BMW 430i 4 Series. Order it as part number KCA473. The kit contains 2 bushings, 2 tubes, adjusting tool, an install guide, and grease. Chassis code: F32/F33. Placement: front. 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.
Expect a difficult job of about 3 hours. Plan on a wheel alignment afterward. Other Whiteline parts we list for the 430i 4 Series: Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Front Sway Bar Link Assembly.
Features
- Bushing material: Made of polyurethane, which resists deflection better than soft rubber.
- Install guide: Whiteline packs an install guide with it.
- Compliance voids: Molded voids give the bushing room to flex where it needs to.
- Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
- Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
- Corrosion protection: Metal parts are plated to resist rust over the long term.
