Dial In Rear Ride Height For Rubicon 4XE Trail Duty
Skyjacker built the JLUER40RDR rear dual rate long travel coil spring for owners of the 2021 to 2024 Jeep Wrangler Unlimited Rubicon JL 4xe who want a 4 inch rear lift that still rides comfortably on pavement. This spring uses a progressive two stage rate so the rear axle settles gently through the first portion of travel and firms up as the suspension compresses further on the trail. The JLUER40RDR is side specific and tuned around the added mass of the Rubicon 4xe battery pack and heavier axle components, keeping ride height level and consistent. Skyjacker finishes each JLUER40RDR spring with a corrosion resistant coating built to hold up in harsh conditions.
Key Features
- Dual rate coil design for a plush first stage and firm second stage
- Side specific engineering for correct rear axle geometry
- Delivers a 4 inch rear lift for larger tire clearance
- Tuned for the added weight of the Rubicon 4xe hybrid system
- Chromium alloy build resists long term sag
- Backed by Skyjacker limited lifetime warranty
