Installation Notes and Tips
Verify the front left position before installation and compare the original bellows to the replacement part for length, diameter, and end fit. Inspect the steering rack, tie rod area, and surrounding boots for wear or damage before reassembly. Confirm vehicle application by year, model, and position for Subaru WRX STI, WRX, and Impreza fitment.
Quality Assurance
Delphi uses OE-based dimensional and material analysis and subjects steering components to extreme temperature and corrosion testing to support consistent aftermarket fit and durability.
