ARB Adjustable Rear Lower Control Arms LCAJKRR

The ARB adjustable rear lower control arms LCAJKRR are engineered to restore and fine-tune rear axle geometry on lifted Jeep Wrangler JK vehicles. After suspension modifications, factory control arms often limit proper axle positioning, negatively affecting handling, driveline angles, and tire wear. These adjustable arms provide the necessary correction to maintain predictable vehicle behavior in all driving conditions.

Detailed description

When a suspension lift is installed, the rear axle shifts from its factory position, which can lead to reduced stability, altered pinion angles, and compromised ride quality. The ARB LCAJKRR rear lower control arms solve this issue by allowing precise length adjustment, enabling accurate repositioning of the rear axle.

Manufactured from thick-wall DOM steel tubing, these control arms are designed to withstand extreme off-road loads while maintaining excellent ground clearance. The integrated high-performance bushings balance durability and vibration control, ensuring long service life without sacrificing driving comfort.

Features and benefits

• Adjustable length – allows accurate rear axle alignment after suspension lifts.
• Heavy-duty DOM steel construction – built to handle severe off-road stresses.
• 50.8 mm diameter, 4.7 mm wall thickness – increased strength and resistance to bending.
• Max C Dual Durometer bushings – optimized for durability, control, and reduced noise.
• Corrosion-resistant finish – zinc coating combined with powder coating for long-term protection.
• Robotic welds – consistent quality and structural integrity.
• Improved handling – enhanced stability, traction, and driveline geometry.
• Suitable for road and off-road use – ideal for daily driving, overlanding, and technical terrain.
