Maximize Your Subaru's Rear Sway Bar Performance with Whiteline

The Whiteline KBR21-20 Heavy Duty Rear Sway Bar Mounting Saddle Kit is engineered to deliver superior performance and durability for your Subaru. Factory sway bar mounts are often a weak point, especially when paired with performance sway bars or subjected to aggressive driving. This kit replaces those stock components with robust, forged alloy versions designed to eliminate flex and ensure your sway bar functions exactly as intended.

Key Benefits of the Whiteline KBR21-20 Kit:

  • Eliminate Mount Flex: Prevents the twisting and distortion of stock mounts, ensuring consistent sway bar performance.
  • Increased Rigidity: Forged alloy construction provides exceptional strength and durability, handling the demands of performance driving.
  • Improved Handling Response: Experience sharper turn-in and a more connected feel to the road by ensuring direct transfer of forces from the sway bar.
  • Reduced Body Roll: Effectively combats body roll during cornering, providing a more stable and confident driving experience.
  • Direct Replacement: Designed as a direct fit for easy installation, replacing the original equipment with a significant performance upgrade.

Extensive Vehicle Compatibility:

This versatile kit fits a wide array of Subaru and Saab models, including:

  • Subaru Impreza: 1993-2007 (Base, Brighton, L, LS, LX, Outback, Outback Sport, RS, TS, WRX, WRX STI)
  • Subaru Legacy: 1990-1999 (GT, GT Limited, L, Limited, LS, LSi, Outback, Outback Limited, Outdoor, Postal, Sport, Sun Sport, SUS)
  • Saab 9-2X: 2005-2006 (Linear, Aero, 2.5i)
