Product Details
This Superlift 4-inch Rock Runner Series Long Arm Kit is built for the 2018-2023 Jeep Wrangler JL Unlimited 4-door models. It features dual-durometer bushings and flex joints with Nylatron races, which are designed to handle the stresses of off-road articulation while maintaining a comfortable ride on the pavement. The long arm design significantly improves suspension geometry compared to shorter arm kits, leading to better handling and control both on and off the trail.
The kit includes long travel coil springs that offer a dual-rate design, providing a softer initial spring rate for better small bump absorption and a firmer rate as the suspension compresses. This helps maintain a comfortable ride during daily driving while still offering the support needed for aggressive off-road use. The included Fox 2.0 shocks are tuned to complement the long arm geometry and dual-rate springs, further enhancing the vehicle's on-road manners and off-road performance. On-vehicle adjustable long arms and track bars allow for precise alignment adjustments after installation, ensuring optimal handling characteristics.
This kit is a comprehensive upgrade for your Wrangler Unlimited, transforming its suspension for more demanding trails and improved driving dynamics. It's important to note that this kit does not fit 2-door models, diesel models, or 392 models. Proper installation will require attention to detail, especially when setting up the adjustable arms and track bars to achieve the best possible alignment and driving experience.
