Rancho 18-22 Wrangler JL 3in Sport Suspension System Component Box 1

This is component box 1 for the Rancho 2-inch Sport suspension system, specifically for your 4-door Jeep Wrangler JL Unlimited from 2018 to 2023. If you're looking to get your Jeep trail-ready, this kit gives you that extra bit of ground clearance needed for rock crawling or just exploring new paths. It's designed to work with your Jeep's factory electronic stability system and allows you to use your original wheels and tires, or even fit up to 35-inch tires with the right wheel setup.

Inside this box, you'll find four corner-specific progressive rate coil springs, which help maintain a level stance even when you're carrying extra gear. It also includes bump stops, extended sway bar end links for both the front and rear, and a bracket to relocate your e-brake line, along with all the necessary hardware. The springs are tuned to offer a good balance between comfortable on-road driving and capable off-road performance. This kit is a bolt-on installation, meaning no welding is required, making it a straightforward upgrade.

Remember, this is component box 1 of 2, so you'll need to order RS66142B-2 to complete the full suspension system. Shocks are sold separately, and while this kit is designed for the JL Unlimited, non-Rubicon models might see a slightly taller lift height compared to Rubicon models. Also, keep in mind that if your Jeep has advanced driver-assistance systems (ADAS), they will need to be recalibrated by a dealer after installation for proper function.
