Part #: 3137

Overview

The Old Man Emu ARB Coil Rear (F&R) springs are engineered specifically for Jeep Wrangler models equipped with 2.0L Turbo, 3.0L EcoDiesel, 3.6L V6, and 6.4L 392 engines from 2018 through 2025.

These springs are part of Old Man Emu’s integrated suspension system philosophy, allowing for precise matching with their shock absorbers to optimize vehicle dynamics. Whether you’re tackling rugged trails or carrying heavy gear on extended trips, these springs deliver improved ride height and superior handling characteristics tailored to your Jeep Wrangler’s specific engine and model year.
