• Fully adjustable design for precise suspension geometry and alignment tuning
• Premium rubber bushings pre-installed at both ends to minimize NVH (noise, vibration, harshness)
• CNC-bent from durable DOM (Drawn Over Mandrel) tubing for strength and consistency
• Forged ends for enhanced durability and resistance to off-road stresses
• Heavy-duty 1-1/4"-12 threaded rods with hex-shaped weld-in bungs for secure, easy adjustments

Construction & Design

The JKS Adjustable Lower Control Arms are crafted from high-quality DOM steel tubing, known for its superior strength and uniformity. The CNC bending process ensures precise shaping to maintain factory suspension geometry while allowing adjustability. Each arm features forged ends that provide exceptional toughness to withstand the rigors of off-road driving and heavy loads.

Pre-installed factory-style rubber bushings at both ends are designed to reduce noise and vibration without sacrificing durability. These maintenance-free bushings eliminate the need for greasing or frequent replacement, making them ideal for all-weather use. The entire assembly is finished with a durable powder coat that protects against rust and abrasion, ensuring long service life.

This kit is designed for direct fitment on 2019 through 2026 Jeep Wrangler JL models equipped with 2.0L Turbo, 3.6L V6, 3.0L EcoDiesel, and 6.4L 392 engines, as well as the 2025 Jeep Gladiator with a 3.6L V6 engine. Installation requires basic suspension knowledge and common hand tools. The adjustable design allows for fine-tuning after installation to achieve optimal alignment and handling characteristics.

No major modifications are necessary, and the included jam nuts and hex-shaped weld-in bungs simplify the adjustment process, making it accessible for experienced DIY enthusiasts and professional installers alike.
