Product Details

This Whiteline Adjustable Rear Sway Bar Link fits the 2019-2025 BMW Z4. It goes on the rear of the vehicle. Application note: Adjustable Extra Heavy Duty. In the box: 2 links. The part number is KLC174.

A sway bar link is the short rod that ties each end of the rear sway bar to the suspension. Whenever the body leans, the link carries that motion into the bar, so any slop, flex, or wear in it is slop in the whole roll-control system. Because the length is adjustable, the link can be set on the car so the bar sits relaxed at rest, which matters most after a change in ride height.

Installation is rated moderate, with about 1 hour of work listed. No alignment is needed afterward. To go with it on the BMW Z4, see Adjustable Sway Bar Vehicle Link Kit, Front Sway Bar Link Kit, and Rear Differential Bushing Kit.

Features

  • Construction: Made from strong, light alloy.
  • Preload-free setup: Length adjustment on the car lets you take preload out of the bar.
  • Install guide: Whiteline packs an install guide with it.
  • Rigid design: Built to remove the flex found in factory parts, so inputs reach the bar sooner.
  • Anodized alloy: The alloy carries an anodized finish for durability.
  • Hardware: Supplied with locking nuts and washers.
