Front Sway Bar Bush Kit Fits Holden Astra Ah 04-On 21mm (DR) SK551 – Transgold
Improve front-end stability, sharpen steering response and eliminate suspension noise in your Holden Astra AH (2004-On) with the Transgold SK551 Front Sway Bar Bush Kit, designed for vehicles equipped with a 21mm internal diameter front sway bar. These bushes secure the sway bar firmly to the chassis, allowing it to properly control body roll and keep the Astra stable and composed during cornering, braking and everyday commuting.
Factory sway bar bushes wear out over time due to heat, age, road grime, potholes and constant suspension movement. When worn, they can cause clunking over bumps, increased body roll, vague steering feedback, poor front-end tracking and a general loss of handling precision. The Transgold SK551 kit replaces these worn bushes with high-quality, OEM-grade rubber components designed for durability, vibration absorption and long service life. Installing this kit restores proper sway bar preload, improves balance and brings back the confident, predictable handling the Astra AH is known for.
Manufactured to strict OEM fitment specifications, this bush kit installs as a direct bolt-on replacement, fitting securely into the factory brackets without any modification required. Whether your Astra AH is daily driven, well-used, or a first car being kept in good condition, Transgold suspension components deliver accurate fitment, reliable performance and long-lasting durability trusted across Australia.
