Overview
The Rubicon Express RE7147FP is a 3.5 inch Super-Flex lift kit for the 4-door Jeep Wrangler JK, supplied with Fox Performance shocks. It is the 4-door counterpart to the 2-door RE7127FP kit in the same family.
Rubicon Express created this kit number for customers who want FOX shocks on the most popular Jeep JK suspension systems. The FOX Performance Series and Performance Series with Reservoir are the shock choices offered in the series.
The FOX Performance Series shocks carry the FOX warranty and do not qualify for the Rubicon Express Advantage Warranty. The rear suspension uses a coil spring kit with a 4-link arrangement.

- Super-Flex short arm front suspension
- Fox Performance shocks included
- Includes adjustable lower control arms

Four-door JK lift considerations
A four-door Wrangler carries a longer wheelbase and extra weight behind the front seats, so the driveline and rear suspension work under different loads than a two-door. The rear driveshaft is longer and runs at a different angle after a lift, which makes driveline checks especially worth doing. Rear coil springs and a 4-link arrangement help control axle position, but passengers and cargo still change the ride height.
Four-door trucks are often used for daily driving, so ride comfort and steering feel matter more day to day. Check the spare tire carrier and any rear accessories for clearance after the lift, since the new ride height can change how they sit. Recheck the alignment after the first few weeks of driving, when settling may show up in tire wear.
- Check rear driveshaft angles after install
- Confirm spare tire clearance
- Recheck alignment after the first few weeks
- Re-examine bump stop contact under full load
