4-Inch Rear Dual Rate Coil Springs for Wrangler Rubicon 392

About this part

4-Inch Rear Dual Rate Coil Springs, fitment-checked

The rear counterpart in Skyjacker's Rubicon 392 spring set — dual rate long travel coils at 4 in., where the front box carries its own height. Front and rear are separate orders.

Front and rear springs are specified separately for the 392 and they are not the same height, so ordering one does not imply the other. This is the rear at 4 in., in dual rate long travel construction: two rates in a single coil, so the Jeep stays compliant unloaded and firms up as weight and articulation demand. Coverage is the 2021-2022 Wrangler Unlimited Rubicon 392 in 4WD. Check the parent kit's parts list to confirm which front box pairs with it.
