AEV Heavy Duty Adjustable Lower Control Arms for JL Wrangler and JT Gladiator

AEV Heavy Duty Adjustable Lower Control Arms are engineered to maintain proper suspension geometry, durability, and ride quality across a wide range of lift heights—while providing the additional clearance required for larger tire packages. 

When paired with AEV’s 4" DualSport Suspension System, these control arms are required for 39" tire fitments, ensuring correct axle positioning, tire clearance, and overall system performance.

Engineered for System Integration

Unlike typical aftermarket solutions that prioritize maximum articulation at the expense of refinement and service life, AEV control arms are designed as part of a fully integrated suspension system. The result is predictable handling, consistent alignment, and long-term durability under increased load conditions.

Key Features & Specifications

Heavy-Duty Construction

• 1.75OD x .25" wall DOM steel tubing provides high strength and resistance to deformation under off-road and on-road loads
• Designed to withstand the increased leverage and stress associated with larger tires and higher ride heights

Wide Range Adjustability

• Compatible from stock ride height up to approximately 6" of lift
• Supports use with or without geometry correction brackets
• Allows precise axle positioning and caster adjustment across varying configurations

Optimized Tire Clearance

• Front control arms feature revised geometry to increase clearance for larger tire diameters
• Critical for proper operation with 39" tires and AEV 4" DualSport Suspension System

OEM-Quality Rubber Bushings

• Maintenance-free design—no lubrication required
• Excellent noise, vibration, and harshness (NVH) isolation
• Eliminates common issues associated with spherical or flex joints, including noise, accelerated wear, and contamination
• Maintains full articulation without introducing harshness or binding

Performance Characteristics

• Maintains factory-like ride quality and handling characteristics
• Preserves suspension kinematics under increased ride height
• Reduces long-term wear compared to typical aftermarket joint systems
• Provides consistent, quiet operation in both on-road and off-road environments

Fitment

• Jeep Wrangler JL (2018+)
• Jeep Gladiator JT (2020+)
• Usable from stock height to ~6" lift
• Required for 39" tires with AEV 4" DualSport Suspension System

AEV Heavy Duty Adjustable Lower Control Arms provide the necessary strength, adjustability, and clearance for larger tire applications while preserving OEM-level refinement and durability. Designed for integration with AEV suspension systems, they deliver consistent performance without introducing additional maintenance or NVH concerns.
