Detailed Product Description

The Delphi TC3085 suspension control arm and ball joint assembly is crafted from aluminum using a combination of casting and forging processes to ensure a balance of strength and reduced weight. This assembly is designed specifically for the front right lower forward position on Mercedes-Benz E-Class models including the E250, E350, E400, and E550. The control arm features a single mounting hole with a diameter of 14.6mm, facilitating secure attachment to the vehicle's suspension system.

The ball joint stud is threaded, measuring 14mm in diameter and 70mm in length, providing a precise fit and reliable connection to the steering knuckle. Natural rubber bushings are used to absorb road vibrations and reduce noise, contributing to a smoother ride quality. This assembly is a standard replacement grade part, intended to restore original suspension performance without requiring additional modifications or adjustments.
