Whiteline Rear Sway Bar 20mm Adjustable – 2000-2004 Subaru Legacy / Outback

Rear Roll Stiffness for the BH/BE Legacy and Outback
The Whiteline BSR12XZ is a 20mm 3-point adjustable rear sway bar for the 2000-2004 Subaru Legacy and Outback (BH/BE chassis). The BH/BE Legacy GT is a capable AWD performance sedan that benefits from rear roll stiffness improvement — the 20mm BSR12XZ provides a meaningful step up from the factory rear bar with three adjustment positions for setup flexibility.

BH/BE Legacy and Outback
The BH/BE Legacy GT and Outback versions of the first-generation B platform Legacy benefit from rear anti-roll improvement. The 20mm BSR12XZ provides balanced improvement for street and mixed-use applications.

Three Positions
Middle for balanced street and spirited driving. Outer for more aggressive rear roll stiffness. Inner for a softer tune when full 20mm is more than needed.

Pair With Front Bar
Whiteline offers front sway bars for the BH/BE Legacy platform. Matched front and rear upgrades produce the most balanced improvement.

The RallySport Take

Rear anti-roll upgrade for the BH/BE Subaru Legacy and Outback. Installation is a straightforward bar swap — remove the OEM bar, install the Whiteline unit with the provided polyurethane mount bushings, connect the endlinks. Start in the middle adjustment position and move from there. Adjustable endlinks are a worthwhile companion purchase if the car has been lowered, ensuring the bar operates at zero preload at the new ride height.
