Product Details
This Whiteline Front Lower Radius Arm Bushing fits the 2015-2016 BMW 428i xDrive Gran Coupe 4 Series. It goes on the front of the vehicle. Chassis code: F36. Whiteline's note for this fit: Adds +/- 0.5 degrees Caster. Does not Suit xDrive Models. In the box: 2 bushings, 2 tubes, adjusting tool, an install guide, and grease. The part number is KCA473.
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.
Whiteline rates the install as difficult and lists about 3 hours. Plan on a wheel alignment afterward. To go with it on the 428i xDrive Gran Coupe 4 Series, see Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Rear Lower Trailing Arm Bushing.
Features
- Grease: Supplied with molybdenum disulfide grease for extended service life.
- Bushing compound: The elastomer formulation is chosen to shrug off oil, grease, ozone, and the elements.
- Bushing material: Made of polyurethane, which resists deflection better than soft rubber.
- Self-lubricating: Built-in grease reservoirs provide continual lubrication and reduce friction.
- Alignment adjustment: Gives an alignment shop a window of adjustment to set the wheels right.
- Install guide: Written install instructions are included with the part.
