Cusco 684311B21 Rear Sway Bar 21mm for Subaru Legacy GT

The Cusco 684311B21 is a 21mm rear sway bar engineered specifically for the Subaru Legacy GT (BP9 chassis) and compatible with V6 naturally aspirated models. This performance upgrade significantly reduces body roll during aggressive cornering while improving overall handling response and driver feedback.

Key Features:

• 21mm solid steel construction for enhanced torsional rigidity
• Direct bolt-on installation with all necessary mounting hardware included
• Powder-coated in signature Cusco blue for corrosion resistance and distinctive appearance
• Includes grease-free replacement bushings for reduced maintenance and longer service life
• Designed to reduce understeer and improve chassis balance under high-performance driving conditions

Cusco sway bars are engineered to provide the optimal balance between street comfort and track-ready performance. By increasing resistance to torsion, this rear sway bar helps stabilize the vehicle during cornering, reduces weight transfer, and gives drivers more confidence when pushing their vehicle's limits. The increased rear stiffness helps dial out understeer while maintaining predictable handling characteristics.
