Weonefit Front Lower Control Arm Kit for 2013–2017 Ford Fusion / 2013–2018 Lincoln MKZ — Pair with Ball Joints & Rust-Resistant St

Weonefit front lower control arm assemblies K623000 and K623001 are direct-fit suspension replacements engineered to restore proper wheel control and ride stability for 2013–2017 Ford Fusion and 2013–2018 Lincoln MKZ models.

These front lower control arm kits (replacement for OEM numbers K623000, K623001 and corresponding DG9Z/GS7Z variants) are built from high-strength steel tubing, feature solid plate mounting brackets and a rust-resistant finish to deliver long service life. Each kit includes both driver and passenger side assemblies, preassembled with ball joints and bushings so you can replace worn arms quickly and get the vehicle back to predictable steering and reduced vibration.

How will this control arm kit affect steering and ride comfort?

Replacing worn or damaged lower control arms helps the suspension keep the wheel aligned under load, which reduces steering wander and cabin vibration. With precise wheel control restored, the vehicle tracks more predictably and drivers often notice improved comfort over rough surfaces.

• Restores correct wheel geometry to reduce uneven tire wear.
• Limits excessive vibration transmitted to the chassis.
• Improves steering response and straight-line tracking.

What signs indicate I need these front lower control arms?

Common symptoms of failing control arms include clunking noises from the front suspension, unpredictable steering, and rapid or uneven tire wear. If you observe any of these warning signs or notice a loose feel in the front end, replacing both left and right assemblies is recommended for balanced handling.

• Clunking or knocking from the front suspension during bumps.
• Steering wander or reduced directional stability.
• Uneven tire wear across the front tires.
• Noticeable vibration in the steering wheel or floorboard.
