TrueDrive RH28150021 Rear Upper Control Arm OEM Replacement 551002G000

The TrueDrive RH28150021 is a direct-fit aftermarket rear upper control arm designed as an OEM replacement for the Hyundai Elantra and Kia Optima/Magentis. This rear lateral arm is engineered to restore proper rear suspension geometry, ensuring correct wheel alignment, stable handling, and a smooth, controlled ride.

This arm serves as a non-adjustable upper rearward lateral link in the rear multi-link suspension system, anchoring the rear hub/knuckle to the subframe and maintaining proper camber and toe characteristics. It is a symmetrical design, meaning the same part serves both the driver and passenger sides.

Key Features:

• Direct OEM replacement — replaces OE part number 55100-2G000
• Includes bushings pre-installed for ready-to-install convenience
• Non-adjustable design matches original equipment specifications
• Symmetrical construction fits both left (driver) and right (passenger) rear positions
• Engineered to restore factory suspension geometry and ride quality
• Compatible with both Hyundai and Kia platforms sharing the same architecture

This control arm is the ideal solution for worn, cracked, or damaged OEM rear lateral arms showing symptoms such as rear wheel misalignment, uneven tire wear, or clunking noises from the rear suspension.
