Fitted to the 2023-2025 Nissan Z: the Whiteline Front Lower Inner Rear Control Arm Bushing Kit. Whiteline part number: W56441. Placement: front. The kit contains 2 bushings, 2 tubes, and grease. The chassis code on the listing is RZ34.
A control arm bushing is the pivot where the arm joins the chassis or the wheel carrier. Factory rubber is chosen for quiet and comfort, so it squashes under braking, acceleration, and cornering and lets the arm move more than it should. A firmer replacement keeps the arm where it belongs, which steadies the alignment and gives the car a more consistent feel. The polyurethane used here deflects much less than the original rubber under the same load.
Whiteline rates the install as moderate and lists about 3 hours. Get the car aligned once it is back on the ground. To go with it on the Nissan Z, see Adjustable Rear Sway Bar Link, Front and Rear Sway Bar Kit, and Rear Upper Inner Control Arm Bushing.
