Energy Suspension: Rock-Flex Suspension Systems for 2018 Jeep Wrangler JL

Though the Wrangler JL offers many advances over the JK, including a well-designed suspension featuring better geometry, the engineers at Energy Suspension believe strongly in that old saying: “There’s always room for improvement.”

The new Rock-Flex suspension system from Energy Suspension captures that adventurous spirit. Using Hyperflex performance polyurethane, Rock-Flex systems create a ride height–adjustable suspension that gives your JL the articulation, control, and off-road performance of a much more expensive off-road suspension while simultaneously enhancing on-road handling. Rock-Flex is less a replacement suspension and more a series of parts that augment the factory suspension (and overcomes the shortcomings of OE rubber components).

This innovative product addresses all the issues associated with lifting a coil sprung Jeep, correcting sway bar geometry and caster without additional modification—allowing the suspension to function properly through its entire range of motion while improving the JL’s already impressive street manners.
