Manufactured from high-quality elastomer or metal–elastomer composite material, this bush ensures smooth articulation of the lifter leaf spring while absorbing vibration and reducing noise. It prevents direct metal-to-metal contact between the spring and mounting pin, minimizing wear and extending component life. The bush maintains correct suspension geometry under varying load conditions, especially during lifting and lowering of auxiliary spring systems. Engineered to withstand heavy loads, continuous movement, and harsh road environments, it enhances suspension stability, improves ride comfort, and ensures reliable performance in demanding commercial vehicle applications.
