The AEV 4" DualSport RT Suspension System for the JL Wrangler Unlimited is engineered to deliver maximum off-road capability without compromising on-road stability, steering precision, or overall vehicle control. As a fully integrated system, it accommodates up to 39" tires when paired with AEV Heavy Duty Adjustable Lower Control Arms, while preserving proper geometry, balanced ride quality, and predictable handling characteristics. Unlike conventional lift kits that prioritize height over performance, the DualSport RT system focuses on optimized wheel travel, corrected steering geometry, and system-wide integration—resulting in a suspension system that performs cohesively in all driving conditions. As with all of AEV’s expedition-ready suspension systems, the 4" DualSport RT Suspension System for the Jeep Wrangler JL is FMVSS No. 126 Compliant. FMVSS No. 126 is a rigorous standard set by the National Highway Traffic Safety Administration (NHTSA) that tests new electronic stability control (ESC) systems by subjecting it to various maneuvers designed to evaluate its effectiveness in preventing loss of control and skidding, including evasive lane-changing maneuvers at highways speeds. Key Benefits Increased Wheel Travel & 39" Tire Capability The DualSport RT system is engineered to provide the wheel travel and clearance necessary to properly run up to 39" tires with OEM fender flares when paired with AEV Heavy Duty Adjustable Lower Control Arms or equivalent aftermarket front lower control arms that provide comparable tire clearance. This delivers improved articulation and off-road traction without sacrificing stability or requiring excessive lift height. Balanced On-Road and Off-Road Performance AEV’s approach prioritizes real-world drivability. By combining frequency-tuned springs with matched damping, this system delivers composed highway manners alongside enhanced off-road capability—eliminating the common trade-offs found in traditional lift kits.
