This new 4.5" Suspension Lift Kit with Military Wrap Leaf Springs provides the perfect blend of off-road performance and a smooth highway ride. The included set of application tuned, lifted military wrapped leaf springs breathe new life into your existing YJ's suspension while offering a unique advantage to serious off-roaders. Military Wrap Leaf Springs have tapered leaves which allows more flex in the leaf ends while distributing loads more evenly, while giving the main leaf extra strength. Most notably, this design works as a fail safe if the main leaf ever breaks - meaning you can limp your rig home when you need to. This kit is also outfitted with Rough Country's N3 Shock Absorbers, nitrogen charged and specifically tested and tuned for YJ applications. This allows for a super smooth highway ride and outstanding control in rugged off road situations all from the same shock.
