Overview

Rock Krawler Starter System Mid-Arm Suspension Lift Kits

Rock Krawler engineers their Starter System JL/LJ suspension kits as ideal entry points into Rock Krawler suspensions, providing the minimum essential geometry correction needed when installing taller coil springs and other components for taller tires without overcomplicating the build. Engineered specifically for Jeep JL/LJ non-diesel models, the multi-rate coil springs help maintain comfortable street manners while keeping enough coil length for trail flex, and the included correction components address common lift-related issues, so the Jeep stays composed and predictable. These systems are complete bolt-in packages (no welding required) and are designed to be upgradable as your build develops--think of them as a foundation that can grow into more comprehensive systems. Get started on a lift system designed to flex hard on the trail, then track straight on the drive home when you order the Rock Krawler Starter System mid-arm suspension lift kit best suited for your JL or LJ application.
