Description

The Cusco 21mm Rear Sway Bar is a direct-fit upgrade for the 2022-2026 Subaru WRX (VB chassis). At 21mm in diameter, it is larger than the factory 19mm bar and delivers roughly 33% more roll stiffness for sharper cornering, better balance, and improved stability.

  • Solid 21mm steel bar - approximately 33% stiffer than the OEM 19mm bar
  • Finished in Cusco's signature blue powdercoat
  • Non-adjustable design with welded end mounts and welded collars
  • Includes bushings and detailed installation instructions - a great do-it-yourself project
  • Part Number: 6A9 311 B21
