Detailed Product Description

This Dorman suspension control arm (part number 520-243) is designed to restore the suspension system on Ford Taurus and Mercury Sable models. Made from high-quality steel, the control arm features a coated black finish that helps resist rust and wear over time. The included rubber bushing, with an inside diameter of 14.3 mm and an outside diameter of 39.6 mm, is engineered to absorb vibrations and reduce noise, contributing to a smoother ride. The control arm measures 262.5 mm in length, matching OEM specifications to maintain proper suspension geometry and vehicle handling.

The control arm’s construction combines casting and forging processes to provide strength and durability under normal driving conditions. It includes a welded ball joint mounting type with a threaded stud, although the ball joint itself is not included. This part does not come with mounting hardware or grease fittings, so those components must be sourced separately if needed.
