Adjustable Sway Bar Link (Single) - E30 M3, E36 M3, E46, Z4

This single swaybar link is adjustable to eliminate preload on the front sway bar in E30 M3, E36 M3, E46, and Z4 models. Preload is tension on the bar when the car is at rest on the ground. Ideally, the bar should be neutral with zero tension on both ends (no twist in the bar at rest). Preload comes from inconsistent side-side ride height (such as with coil overs), a bent swaybar, a bent strut housing, or a chassis with bent or skewed frame rails. The handling is affected with a preloaded sway bar so removing that tension will give you more consistent handling and response. Preloading can also lead to premature failure of the link ball joints.

To remove preload you only need an adjustable link on one side of the car. Install your stock swaybar link on one side, lower the car to the ground, adjust the Turner link to meet the swaybar hole on the other side, and tighten everything up. Never install both sway bar links with the tires off the ground. Our link is made from a stock HD swaybar link with an easily adjusted hex rod in the middle.

One link or two? Technically, the remove preload only one link is required. However, there may be cases where having two links is better. Having an adjustable link on both sides of the car will allow you to better position the front sway bar for clearance or when a different racing style coil over is used.
