Wrangler JL/JLUR Coil Springs

The right coil spring rate is what keeps the Wrangler JL/JLUR sitting level under real-world load instead of sagging back down within a few months. Getting spring rate right depends on your actual vehicle weight, lift height, and accessories rather than a single off-the-shelf number. Go too soft and the ride sags or bottoms out under load; go too stiff and every bump transmits straight into the cabin, which is why getting the rate matched up front saves a second purchase down the road.

Eibach is the name that comes up most often in coil spring research, known for precision-engineered rates across a wide range of vehicle weights: AccuTune matches spring rate to your specific build rather than defaulting to a single off-the-shelf option.
