Wrangler JK 2007-2018 Jeep 4WD - Adjustabled Rear Upper J-Link Control Arms by JKS

JKS1639 J-Link Adjustable Control Arms for Jeep Wrangler JK models are engineered to deliver improved suspension strength, precise geometry correction, and long-term durability for lifted applications. Designed for both daily driving and aggressive trail use, these adjustable control arms allow accurate alignment tuning while maintaining a smooth, controlled ride.

Each arm is CNC-formed from heavy-duty DOM tubing and features a forged, adjustable end for exceptional strength and reliability. The fully adjustable design allows fine-tuning of caster and axle positioning to restore proper suspension geometry after lifting. Heavy-duty 1"-12 threads combined with hex-shaped weld-in bungs make adjustment simple while ensuring the jam nuts tighten securely.

Premium factory-style rubber bushings come pre-installed at both ends to provide maintenance-free operation and superior isolation from noise, vibration, and harshness.
