AEV JL 4" DualSport Suspension Kit - Gas, RT5100
The AEV 4" DualSport RT Suspension System is the definitive choice for JL Wrangler 4-Door owners who demand maximum trail capability without sacrificing world-class highway manners. Engineered as a fully integrated solution rather than a collection of parts, this system provides a substantial 4-inch lift that is specifically tuned to handle the added weight of steel bumpers, winches, and overland gear. By utilizing AEV’s signature frequency-tuned, triple-rate coil springs and custom-valved Bilstein 5100 shocks, the DualSport RT delivers a composed, predictable ride that excels during high-speed desert crossings and technical rock crawling alike.
Beyond simple ride height, this system prioritizes steering precision and geometric perfection. It includes a comprehensive High Steer System and geometry correction brackets that restore factory-spec handling dynamics, effectively eliminating bump steer and improving braking nose-dive. For the Jeep enthusiast looking to run up to 39-inch tires while maintaining the refinement of an OEM-level build, the AEV 4" DualSport RT offers a level of sophistication and durability that sets a new industry standard.
Massive Tire Capability: When paired with AEV’s heavy-duty adjustable control arms, this system allows you to properly fit up to 39-inch tires with factory flares. This provides significant ground clearance and a dominant footprint for the most demanding off-road environments.
Comprehensive High Steer System: Unlike basic lift kits, the RT system includes a full High Steer kit with cast iron knuckles and a heavy-duty drag link. This corrects the steering geometry to keep the drag link and track bar in perfect alignment, ensuring sharp, effortless steering even with oversized rubber.
Frequency-Tuned Triple-Rate Springs: AEV’s proprietary spring technology is designed to provide a soft initial rate for small bump compliance, transitioning into a firmer rate to support heavy cargo and high-speed impacts. This ensures the Jeep remains level and stable under various load conditions.
Optimized Geometry Correction: The included stamped geometry correction brackets drop the front control arm mounting points, which restores the proper caster angle and flattens the arm's operating arc. This results in a much smoother ride over expansion joints and significantly improved stability during hard braking.
OE-Level Integration and Compliance: Every component is designed to work in harmony, maintaining the effectiveness of your Jeep’s Electronic Stability Control (ESC) systems. This "total vehicle" engineering approach provides peace of mind that your rig remains safe and predictable on the road.
