🧾 Overview
The TeraFlex 3.5" Coil Spring Base Lift Kit for the Jeep Wrangler JL Unlimited is designed to provide significant ground clearance and support for larger tires using core suspension components only. This base lift system focuses on lift height and articulation, making it an ideal foundation for Jeep owners who plan to build out their suspension in stages.
Because this is a base lift and not a complete suspension system, additional components are required to properly correct suspension geometry at 3.5 inches of lift. When paired with longer front control arms or control arm brackets and adjustable track bars, this system can be tuned to deliver capable trail performance while maintaining safe and predictable handling.
✔ 3.5" suspension lift for JL Unlimited
✔ Coil-spring-based system for increased clearance and articulation
✔ Designed as a foundation for custom suspension builds
✔ Supports up to 37" tires with proper configuration
✔ Compatible with aftermarket shock upgrades
🛠 Installation
- Bolt-on installation using factory mounting points. No cutting or welding required. Due to the lift height, additional suspension components are required for proper geometry correction. Professional installation and alignment are strongly recommended.
