ARB Old Man Emu front coil springs for the Jeep Wrangler JK 4" lift are engineered for more aggressive builds running larger tires and heavier front-end accessories. At 4" of lift, spring rate and geometry correction become critical — these OME coils are specifically valved to maintain correct front-end geometry, prevent excessive body roll, and support the added weight of winches and bull bars.
