Product Details

This Whiteline Adjustable Rear Sway Bar Link fits the 2016-2020 BMW 420i 4 Series. The part number is KLC174. In the box: 2 links. Application note: Adjustable Extra Heavy Duty. This part is for the rear of the vehicle.

Links are small parts with a large effect on how a car leans in a corner. They sit between the bar and the suspension and decide how quickly and how evenly the bar's resistance reaches the tire, and this rear link is built to keep that connection firm. Its adjustable body lets you set the length with the car on the ground, so the bar is not twisted against its own mounts before the car even moves.

Whiteline rates the install as moderate and lists about 1 hour. No alignment is needed afterward. Other Whiteline parts we list for the 420i 4 Series: Front Sway Bar Link Assembly and Front Lower Radius Arm Bushing.

Features

  • Preload-free setup: The link can be set to length on the vehicle to remove bar preload.
  • Ball joints: Heavy duty steel ball joint ends pivot freely through a wide range, which helps fitment.
  • Hardware: Hardware supplied: locking nuts and washers.
  • Install guide: An install guide comes in the box.
  • Rigid design: Taking the flex out of the connection makes the car react faster to steering input.
  • Anodized alloy: Anodized alloy parts resist corrosion and wear and look good doing it.
