Front Left & Right Upper Control Arm

The purpose of these front upper control arms with integrated ball joints and bushing assemblies is to provide a critical connection between your Infiniti vehicle’s chassis and wheel assembly, maintaining proper wheel alignment during suspension movement while absorbing road impacts for enhanced stability and handling precision.

Components of the Automobile Steering Control System:

Materials: Constructed from premium aluminum for optimal strength-to-weight ratio and superior durability, engineered to withstand the stresses of daily driving and resist fatigue over extended use in various road 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 Infiniti applications.

Design: Features an integrated ball joint design that eliminates potential failure points and provides seamless movement. Pre-greased components ensure extended lifespan and smooth operation while precision-engineered bushings reduce noise, vibration, and harshness (NVH) for improved ride comfort.

Function: Serves as a critical suspension component that controls wheel motion during acceleration, braking, and cornering, maintaining proper alignment and ensuring optimal tire contact with the road surface for predictable handling and maximum traction.

Load Capacity: Engineered to withstand significant vertical and lateral forces during cornering, emergency maneuvers, and varying load conditions while maintaining precise suspension geometry for consistent handling performance.

Installation: Direct OEM replacement design (RK621600, RK621601) for straightforward installation, restoring factory suspension geometry for 2015 Infiniti Q40, 2011-2012 Infiniti G25, 2009-2013 Infiniti G37 Sedan, and 2007-2008 Infiniti G35 Sedan models.
