About this part

3.5-Inch Component Box, fitment-checked

The Rubicon-specific 3.5 in. box, covering Rubicon, Rubicon Deluxe and Rubicon X from 2018-2025 in 4WD. A Rubicon starts higher than a Sport does, so it takes different spring rates to land at the same finished height: hence a separate part number.

Trim matters more than usual on a JL lift. The Rubicon leaves the factory taller than the other trims, so a box calibrated for a Sport will overshoot on a Rubicon and vice versa. This one is cut for Rubicon, Rubicon Deluxe and Rubicon X across 2018-2025 in 4WD. At 85.3 lb boxed it carries more than the non-Rubicon equivalent. Two exclusions still apply: diesel models and the Rubicon 392, which has its own listing.
