The tie rod end rubber is a vital replacement part for classic Citroën models like the 11CV, 15CV, and HY. This rubber component provides cushioning and vibration isolation between the tie rod ends and the suspension, essential for a smooth and controlled driving experience. Over the years, the rubber can dry out and crack, making replacement necessary to maintain vehicle performance. Specifically designed to match the original specifications of these iconic classic cars, the tie rod end rubber helps preserve the original driving experience and vehicle stability.
