The SPC Performance Rear Lower Control Arm is a direct-fit replacement designed specifically for Jeep Wrangler models from 2018 through 2024, including the Wrangler JK from 2018. Engineered to enhance the strength and articulation flexibility of your vehicle’s rear suspension, this control arm is ideal for both stock-height and lifted Wrangler setups.

Built to withstand the demands of off-road articulation, the SPC Performance Lower Control Arm ensures smooth, bind-free movement between the frame and axle. It is a perfect upgrade for Jeep enthusiasts looking to improve suspension articulation without compromising noise, vibration, or harshness (NVH) levels.

Key Features:

Designed with advanced technology and durable materials, this rear lower control arm offers several key benefits:

• Direct-fit, stock-length design for easy installation on 2018–2024 Jeep Wrangler and 2018 Wrangler JK models
• SPC’s patented xAxis sealed flex joint provides maintenance-free, bind-free articulation for improved off-road performance
• OE-style bonded rubber bushing on the frame end reduces noise, vibration, and harshness (NVH) for a quieter ride
• Corrosion-resistant coating protects against rust and environmental damage, extending component life
• Self-lubricated xAxis joint eliminates the need for regular maintenance or greasing
• Enhances suspension strength and articulation flexibility for both stock and lifted suspension setups
• Compatible with a wide range of Jeep Wrangler trims including Rubicon, Sahara, Sport, Willys, and special editions

Construction & Design:

The SPC Performance Rear Lower Control Arm is engineered with high-strength materials and advanced manufacturing techniques to ensure durability and reliability in demanding conditions. The arm features a sealed xAxis flex joint that allows for smooth, multi-axis movement without binding, which is critical during extreme off-road articulation. This joint is self-lubricating and sealed to prevent dirt and moisture intrusion, significantly reducing maintenance requirements.

At the frame end, an OE-style bonded rubber bushing is incorporated to absorb vibrations and minimize noise, preserving the comfort and refinement expected from a factory suspension component. The entire control arm is finished with a corrosion-resistant coating, providing superior protection against rust and wear caused by exposure to water, mud, and road salt.

Installation & Fitment:

This rear lower control arm is a direct replacement for the factory unit, designed to fit Jeep Wrangler models from 2018 to 2024 and the 2018 Wrangler JK without any modifications. Installation is straightforward and can typically be completed with basic hand tools. The stock-length design ensures that suspension geometry remains correct, whether your vehicle is at stock ride height or equipped with a lift kit.

Because the xAxis joint is self-lubricating and sealed, no additional maintenance or greasing is required after installation, making it a hassle-free upgrade for off-road enthusiasts and daily drivers alike.

What's Included:

• One SPC Performance Rear Lower Control Arm (stock-length)
