🧾 Overview
The TeraFlex Gladiator 4.5 Inch Coil Spring Base Lift Kit is a foundational suspension upgrade designed to deliver significant ride height and tire clearance for Jeep Gladiator JT owners planning a staged or custom suspension build. This base lift includes only essential lift components and does not provide the full drivability or geometry correction of a complete suspension system.
Engineered as a starting point for advanced builds, this kit requires the addition of front control arm Sport Frame Brackets or adjustable control arms, along with adjustable track bars, to properly correct suspension geometry. For maximum capability, TeraFlex also recommends pairing this base kit with an Extended-Travel suspension system.
Note: Shocks are not included. Falcon Performance Shocks are strongly recommended, as they are engineered to work with TeraFlex lift coil springs for optimal compression, rebound, and vehicle stability.
