Rear Upper Control Arm

The purpose of the rear upper control arm is to provide critical geometry control of the suspension system, maintaining proper camber and toe alignment while absorbing road impacts, ensuring vehicle stability, and delivering precise handling characteristics during all driving conditions.

Components of the Automobile Steering Control System:

Materials: Constructed from premium high carbon steel for exceptional strength-to-weight ratio and enhanced durability, engineered to resist deformation and fatigue over extended use in demanding driving conditions.

Safety: Manufactured in strict compliance with IATF 16949 and ISO 9001 quality standards to ensure consistent safety, reliability, and performance that meets or exceeds OEM specifications for multiple vehicle applications.

Design: Features curved arm geometry precisely engineered to maintain optimal suspension geometry throughout suspension travel. Integrated high-performance bushings reduce noise, vibration, and harshness (NVH) while improving overall ride comfort and handling precision.

Function: Serves as a critical link between the vehicle chassis and wheel assembly, controlling the camber angle of the wheels during suspension compression and rebound, ensuring consistent tire contact with the road surface for optimal handling and braking performance.

Load Capacity: Engineered to withstand significant torsional and lateral forces during aggressive cornering, emergency maneuvers, and varying load conditions while maintaining precise suspension geometry.

Lubrication: Pre-greased with high-performance automotive lubricant to ensure smooth articulation of all moving components, minimizing friction, preventing premature wear, and extending service life without requiring additional maintenance.

Installation: Direct OEM replacement design (RK641942) enables straightforward installation with precise fitment across multiple vehicle platforms, restoring factory suspension geometry for 2006 Lincoln Zephyr, 2007-2012 Lincoln MKZ, 2006-2012 Ford Fusion, 2006-2011 Mercury Milan, and 2003-2008 Mazda 6 models.
