A Dedicated Rear Spring Upgrade for the Non Rubicon 4XE
The Skyjacker JLUE40RDR is a rear dual rate coil spring designed for the 2021-2024 Jeep Wrangler Non-Rubicon 4XE, addressing the added rear weight from the plug in hybrid battery and drivetrain components. Rather than a full component box, the JLUE40RDR lets Sport and Sahara 4XE owners upgrade just the rear spring rate, correcting rear ride height sag that the hybrid battery pack can introduce on a Non-Rubicon 4XE.
The dual rate design of the JLUE40RDR provides a softer initial spring rate for comfortable everyday driving, then progressively firms up as the rear suspension compresses further under cargo load or trail articulation. This keeps the rear of the Non-Rubicon 4XE level and controlled without the harsh ride a single rate heavy duty spring can introduce. The JLUE40RDR is a straightforward way to correct rear stance on a 4XE that has sagged from added hybrid component weight.
