What's included
- 3.5-inch coil spring kit (front) — Dual-rate design that keeps your suspension responsive on pavement while handling rough terrain with confidence.
- 3.5-inch coil spring kit (rear) — Progressive spring rate tuned to your new ride height for balanced load support and articulation.

Important notes
- Does NOT fit 2020–2023 Gladiator JT models equipped with the 3.0L EcoDiesel V6 engine due to motor weight variance.
