Part #: JKS1671

Overview

The JKS Manufacturing J-Link Fixed Length Rear Lower Control Arms are engineered specifically for the Jeep Wrangler JL model years 2018 through 2026. Designed to correct suspension geometry and enhance durability, these heavy-duty control arms are an essential upgrade for Jeep owners who have installed lift kits or seek improved handling and axle alignment. By replacing the factory rear lower control arms with these fixed length J-Link arms, you gain stronger components that help recenter the axle within the wheel well, ensuring optimal performance and ride quality.

Ideal for off-road enthusiasts and daily drivers alike, these control arms maintain proper suspension angles and reduce unwanted axle movement, which can lead to uneven tire wear and compromised handling. The J-Link arms are a direct bolt-on replacement that fit within the original equipment mounting points, making them a straightforward upgrade for Jeep Wrangler JL owners looking to enhance their vehicle’s suspension system.

• Fixed length design to maintain correct suspension geometry on lifted vehicles
• 1/4" longer than stock rear lower control arms to help recenter the axle in the wheel well
• Constructed from 2" OD x .250-wall DOM tubing for superior strength and rigidity
• Pre-installed premium OE style rubber bushings at both ends to reduce noise and vibration
• Gloss black powder coat finish for corrosion resistance and long-lasting durability
• Direct bolt-on installation using original equipment mounting locations
• Compatible with lift heights ranging from 0 to 4.5 inches
• Can be used in conjunction with JKS Jspec systems to eliminate the need for lower cam lock modifications
• Manufactured in the USA and backed by JKS’s limited lifetime warranty

Construction & Design

The J-Link rear lower control arms are crafted from high-quality DOM (Drawn Over Mandrel) steel tubing, measuring 2 inches in diameter with a .250-inch wall thickness. This robust construction ensures exceptional strength and resistance to bending or flexing under demanding off-road conditions. The arms are precision-engineered to be slightly longer than stock, which corrects axle positioning and suspension geometry after lifting the vehicle.

Each arm is finished with a durable gloss black powder coat that protects against rust and environmental damage, extending the lifespan of the components. The use of premium OE style rubber bushings at both mounting points absorbs road noise and vibrations, delivering a quieter and more comfortable ride without sacrificing performance.

Installation & Fitment

Installation of the JKS J-Link Fixed Length Rear Lower Control Arms is straightforward and requires no modifications to your Jeep Wrangler JL. These arms install directly into the factory mounting locations and are compatible with lift kits ranging from 0 to 4.5 inches. The fixed length design ensures proper axle alignment and suspension geometry without the need for additional adjustments or cam lock modifications when used with JKS Jspec systems.

Professional installation is recommended to ensure proper torque specifications and alignment, but experienced DIY enthusiasts will find the process manageable with basic hand tools.
