JKS Manufacturing Jeep Wrangler JK Adjustable J-Flex Upper Control Arms - Rear

The JKS Manufacturing Jeep Wrangler JK Adjustable J-Flex Upper Control Arms for the rear are high-performance suspension components designed to improve off-road capability and vehicle reliability. Constructed from stout DOM tubing and CNC-bent for precise fitment, these control arms feature a fully adjustable design that allows for fine-tuning of suspension geometry. The ends are fully rebuildable and greaseable, ensuring long-term durability and ease of maintenance. Heavy-duty 1-1/4"-12 threads combined with hex-shaped weld-in bungs make tightening the included jam nuts quick and secure. Factory-style rubber bushings at the non-adjustable end provide quiet, maintenance-free operation, while the powder-coated finish enhances corrosion resistance and longevity. Sold in pairs, these arms are built for serious off-road use.

Designed specifically for 2007-2018 Jeep Wrangler JK models, these adjustable control arms are suitable for vehicles with stock or lifted suspensions. They serve as a direct replacement upgrade for the rear upper control arms, offering improved articulation and suspension tuning for off-road adventures. Installation is a bolt-on process, compatible with factory mounting points, and ideal for off-road enthusiasts seeking enhanced suspension performance. The kit includes two control arms, ready to improve your Wrangler JK’s off-road handling and reliability. These control arms are perfect for off-road driving, rock crawling, and trail riding, providing a durable and adjustable solution for demanding terrain.
