Cusco 21mm Rear Sway Bar for 2005-2009 Subaru Legacy (684 311 B21)
$274.50 $305.00
$274.50 $305.00

Fits 2005-2009 Subaru Legacy (2.5i, 3.0 R, GT, GT Limited, and GT spec.B).

The Cusco rear sway bar is a core suspension upgrade designed to reduce body roll and improve cornering stability without sacrificing daily ride quality. By increasing the torsional rigidity of the rear suspension, this 21mm bar keeps the chassis flatter through high-speed turns, providing more predictable handling and improved tire contact patches.

Each bar is manufactured from high-strength spring steel and finished in Cusco's signature blue powder coat for long-term corrosion resistance. This component is designed as a direct replacement for the factory unit and bolts into the original mounting points for a straightforward installation.
