Overview

The JKS J-Link Fixed Length Front Lower Control Arms are engineered to enhance the handling, geometry, and overall capability of your Jeep Wrangler JL or Gladiator JT from model years 2018 through 2026.

• Direct bolt-on installation using original equipment (OE) mounting locations
• Compatible with 0 to 4.5 inches of suspension lift without additional modifications

• Backed by JKS’s limited lifetime warranty for peace of mind
• Can be used in conjunction with JKS JSPEC systems as a replacement for lower cam lock modifications

Construction & Design

JKS Manufacturing builds these front lower control arms in the USA using DOM (Drawn Over Mandrel) steel tubing, known for its exceptional strength and uniformity. The 2-inch outer diameter tubing with a .250-inch wall thickness ensures these arms withstand the rigors of off-road driving and heavy-duty use. The arms are carefully formed to provide necessary clearance for larger tires, preventing interference during suspension articulation.

Each arm is finished with a durable gloss black powder coat that protects against corrosion, road debris, and environmental wear. The inclusion of premium OE-style rubber bushings at both mounting points absorbs road noise and vibration, enhancing ride quality without sacrificing performance.

Installation & Fitment

The JKS J-Link Fixed Length Front Lower Control Arms are designed for a straightforward, bolt-on installation using your Jeep’s original equipment mounting points. They fit Jeep Wrangler JL and Gladiator JT models from 2018 through 2026 and accommodate suspension lifts ranging from 0 to 4.5 inches. No additional modifications or special tools are typically required, making them an accessible upgrade for enthusiasts and professional installers alike.

These arms are engineered to correct front caster angles and improve axle positioning, which is especially beneficial when paired with lift kits. When combined with JKS JSPEC suspension systems, the J-Link arms eliminate the need for lower cam lock modifications, simplifying the suspension setup process.
