Product Details
This Whiteline Front Lower Radius Arm Bushing fits the 2017-2019 BMW 430i xDrive 4 Series. This part is for the front of the vehicle. Whiteline's note for this fit: Adds +/- 0.5 degrees Caster. Does not Suit xDrive Models. The kit contains 2 bushings, 2 tubes, adjusting tool, an install guide, and grease. Whiteline part number: KCA473. It is listed for the F32/F33 chassis.
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.
Whiteline rates the install as difficult and lists about 3 hours. Plan on a wheel alignment afterward. To go with it on the 430i xDrive 4 Series, see Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Rear Lower Trailing Arm Bushing.
