Whiteline 22mm Front Sway Bar Mount Bushing Kit – 2002-2007 Subaru WRX (Sedan & Wagon) / 2004-2007 Subaru STI / 2003-2007 Subaru Impreza (Non-Turbo)

Whiteline 22mm Front Sway Bar Mount Bushing Kit – 2002-2007 Subaru WRX (Sedan & Wagon)

The Standard Front Bar Diameter Mount Bushing for the GD WRX
22mm is the most common front sway bar diameter on the GD WRX platform — matching both many OEM configurations and Whiteline’s popular 22mm adjustable front bars. This polyurethane mount bushing replaces worn rubber mounts and keeps the front sway bar firmly located under cornering loads, delivering the full anti-roll performance of whatever bar you’re running.

DETAILS

• 22mm front sway bar mount bushing for 2002-2007 Subaru WRX (sedan and wagon)
• Whiteline polyurethane compound
• Knurled inner bore for grease retention
• Direct-fit to OEM front mount bracket
• Limited Lifetime Warranty

The Most Common GD WRX Front Bar Size
22mm is the diameter of the Whiteline BSF33Z, BSF33, and related front sway bar options for the GD WRX. It’s also a common OEM size. Whether you’re refreshing factory mounts or installing a Whiteline 22mm bar, this is the correct bushing.

Knurled ID — Quiet for the Life of the Install
The knurled inner bore physically holds grease between the bar and bushing surface. This is why properly installed Whiteline bushings don’t develop the squeak that plain polyurethane bushings often do — the grease doesn’t migrate out.

Check Your Bar Size First
Measure or confirm your front sway bar diameter before ordering. The most common size on the GD WRX is 22mm, but not universal. This bushing is sized to match 22mm bars only.

Why Choose Whiteline

Whiteline has been engineering suspension components from their facility in Australia since 1979. Every product in their catalog is developed with a clear goal: measurable improvement in handling, stability, and tyre contact. Whiteline’s polyurethane bushings, sway bars, control arms, and alignment correction kits are engineered using finite element analysis and validated on track before they reach the market. Their components are direct-fit, bolt-on solutions designed for enthusiasts who want real performance gains without fabrication or custom work.

The RallySport Take

If your GD WRX front sway bar is 22mm and the mount bushings are original rubber, these are worth replacing. Improved bar location makes a subtle but real difference in front end response. 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.
