Buy Control Arm (Rear Lower), KK (52125322AE)

The Control Arm (Rear Lower), KK (52125322AE) is a key suspension component

engineered for vehicles such as the Jeep Liberty (KK: 2008–2012) hand Dodge Nitro (2007–

2011). Manufactured as an OEM Mopar part, it meets strict factory standards for strength,

durability, and fitment precision. Its role in the rear suspension system is crucial: it supports

the rear axle, helps manage wheel movement, and hcontributes to ride stability, handling balance, and overall vehicle safety.

Positioned on the lower portion of the rear suspension, the 52125322AE control arm connects

the vehicle’s frame or subframe to the rear wheel hub assembly. This connection provides a

controlled pivot point for the rear wheel as it moves over varying road surfaces. By guiding

vertical and lateral movement, this control arm ensures consistent tire contact with the road,

which enhances traction, smoothness over bumps and dips, and predictable handling through curves and during acceleration or braking.

Constructed from high‑strength stamped steel

Constructed from high‑strength stamped steel and featuring integrated bushings, the rear lower control arm is designed to withstand continuous load and impact stresses. The durable metal construction provides structural rigidity, while the bushings absorb vibration and shocks transmitted from the road surface, reducing noise and harshness felt inside the cabin. The overall design helps prevent premature wear on suspension and drivetrain components.

Part number 52125322AE replaces earlier iterations such as 52125322AC and 52125322AD, incorporating incremental improvements for increased longevity and performance. It is typically sold individually, though in practice both rear lower control arms are often replaced in pairs to maintain balanced suspension geometry and handling consistency.

Over time, the rear lower control arm and its bushings can wear due to continuous motion, exposure to road debris, moisture, and temperature fluctuations. Common symptoms of wear include clunking or popping noises from the rear suspension, uneven tire wear, instability during acceleration or braking, and a loose or wandering feel while driving. Ignoring these signs can accelerate wear on other suspension elements and compromise vehicle safety.

Installation of the 52125322AE generally requires basic suspension tools, proper torque settings, and a post‑replacement wheel alignment to ensure correct rear suspension geometry.

Overall, the Control Arm (Rear Lower), KK (52125322AE) is an essential component that enhances ride comfort, improves handling precision, and supports long‑term suspension durability in compatible Jeep and Dodge vehicles.
