Product Details
This Whiteline Front Lower Radius Arm Bushing fits the 2014-2016 BMW 428i xDrive 4 Series. Application note: Adds +/- 0.5 degrees Caster. Does not Suit xDrive Models. Placement: front. It is listed for the F32/F33 chassis. You receive 2 bushings, 2 tubes, adjusting tool, an install guide, and grease. Part number KCA473.
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.
Expect a difficult job of about 3 hours. Plan on a wheel alignment afterward. To go with it on the 428i xDrive 4 Series, see Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Rear Lower Trailing Arm Bushing.
Features
- Install guide: Instructions for fitting are packed in the box.
- Alignment adjustment: Adds adjustment so the alignment can be optimized.
- Self-lubricating: Built-in grease reservoirs provide continual lubrication and reduce friction.
- Bushing compound: The bushing material stands up to oil, grease, ozone, and weather.
- Bushing material: The bushing material is polyurethane, a firmer choice than rubber.
- Corrosion protection: A protective plating covers the metal components to guard against corrosion.
