🧾 Overview
The TeraFlex Wrangler JL / Gladiator EcoDiesel 1" Front Coil Spring Spacer Adjustment Kit is designed to properly level the front suspension on JL Wrangler and JT Gladiator models equipped with the heavier 3.0L EcoDiesel V6 engine. This kit is required when using TeraFlex coil spring lift kits on EcoDiesel-equipped vehicles to restore correct front ride height and suspension geometry.
For gas-engine JL and JT models, this kit can also be used as a 1-inch front load-leveling spacer, helping compensate for added weight from aftermarket accessories such as steel bumpers, winches, larger spare tires, or overland gear—without replacing factory springs.
✔ Required for EcoDiesel models with TeraFlex coil spring lifts
✔ Restores proper front ride height and leveling

✔ Simple, bolt-on spacer solution
