Precision Tuning with Adjustable Control Arms
JKS lower control arms offer over 3 inches of length adjustment, giving users the flexibility to increase, decrease, or match OE suspension arm length. This adjustability enables fine-tuning of suspension geometry for proper axle housing alignment, optimized tire clearance, and reduced drivetrain stress.
Engineered for Maximum Travel and Durability
Each control arm end is designed to rotate independently, maximizing articulation during extreme suspension movement off-road. The arms use precision-machined fine-thread shafts combined with greasable internal brass bearings, ensuring smooth, quiet operation and long-term reliability in demanding conditions.
Heavy-Duty Construction Built to Last
Constructed from heavy-gauge steel tubing and expertly MIG welded, JKS control arms are significantly stronger than OEM components and provide outstanding resistance to trail impacts. A dual-layer finish—powdercoat exterior with zinc plating—offers exceptional protection against corrosion, grime, and weather exposure.
Comfortable Ride with OE Rubber Bushings
To maintain road comfort, each arm includes premium OE-style rubber bushings that effectively isolate vibration and road noise. Unlike polyurethane alternatives, these bushings reduce chassis stress and improve compliance, making them ideal for daily driving and rugged trail use.
