555 Lower Control Arm

The 555 (Sankei 555) lower control arm line offers OE-style replacement suspension control arms for restoring factory ride, handling and alignment. The lower control arm links the steering knuckle or wheel hub to the vehicle's frame or subframe. It lets the wheel move up and down with the road while holding its position. Worn bushings, ball joints or bent arms can cause clunking noises, vague steering, uneven tire wear and poor alignment.

Key Features:

• OE-style replacement design: Built as a direct replacement for the original control arm.
• Japanese OE supplier heritage: Sankei 555 is known as a Japanese original equipment supplier and is widely used as an aftermarket upgrade over generic parts.
• Durable construction: Made from steel or aluminum, depending on the part, and built for long-term service.
• Restores suspension geometry: Helps bring back stable handling, steering response and ride comfort.
• Convenient assemblies: Many applications come as complete arms with the ball joint and bushings already installed, which simplifies installation. Check the individual part listing for the exact configuration.

Replacing a worn lower control arm helps eliminate suspension noise and restores confident handling. Choose the specific part number for your application to get the correct position and configuration. Replace worn control arms, and have the alignment checked after installation.
