The Zone Offroad 4.5" XJ system with rear leaf springs includes all of the high quality parts necessary at a very affordable price. This system includes made in the USA coil springs that will not sag. The key is using the correct size wire with the correct spring rate to offer the perfect ride and still hold up over time. In fact, the system includes just 2" bump stop extensions to drastically increase wheel travel.
This system also comes with extended sway bar links to compensate for the lift and brake line relocation brackets which makes the job easy to do at home. New extremely heavy duty lower control arms are supplied to correct alignment as well as axle location. These lower control arms are made from heavy wall tube and include pre-installed factory style rubber bushings to absorb the road rather than transmitting it into your seat.
The rear is lifted via new Zone Offroad leaf springs. Many hours of development and testing have finally produced a capable spring that we are proud to introduce to our lineup. The new springs are a 5 leaf pack with anti-friction pads and center leaf spacer plates between each leaf. This design greatly decreases leaf pack internal friction. These springs are designed to give 3" of lift and are also set up to give the max amount of compression travel before the shackle is limited by the rear portion of the body. This allows the springs to flatten out as much as possible, which translates to increased wheel travel. These are designed to flex, but can still hold up and handle your load of gear. To achieve 4" of lift in the rear, longer greasable boomerang shackles have been added to improve articulation while improving the pinion angle.
