OE-Style Suspension Control Arm Assembly

The Suspensia X18CJ1599 is a suspension control arm and ball joint assembly built for direct OE fit and OE appearance. It is engineered for the rear left upper rearward position on select Genesis and Hyundai models, with fitment that matches the listed applications.

  • Direct OE fit and OE look for straightforward replacement.
  • Machined ball joint mounting type with a threaded stud.
  • Rubber bushings and dust boot included for a complete assembly.
  • Black bushings and boot for a factory-style appearance.
  • Locking nut included; castle nut and cotter pin are not included.

Fitment Details

Fits 2017-2020 Genesis G80, rear left upper rearward. Fits 2015-2016 Hyundai Genesis, rear left upper rearward. This part number is X18CJ1599, and it cross-references Delphi TC6934 for the same application.

What It Helps Address

  • Excessive play in the suspension linkage.
  • Clunking or looseness from a worn ball joint.
  • Degraded ride control from worn bushings.
  • Uneven suspension geometry at the rear corner.

Installation Notes

Verify the rear left upper rearward position and confirm stud thread size M14 before installation. The assembly uses a threaded ball joint stud and includes a locking nut, while the castle nut and cotter pin are not included. Confirm the vehicle application against the listed fitment before ordering.
