The Zone Offroad 4.5" 86-92 Jeep Comanche MJ lift includes new front coil springs capable of handling anything! Since we design our coil springs for off road use, there is only a 2" bump stop extension supplied to drastically increase wheel travel. Our coils can be smashed to the bottom and will always come back! No, that doesn't mean they are stiff. The key is using the correct size wire with the correct spring rate to offer the perfect ride and still hold up over time. Unlike many inexpensive kits on the market, our springs are made in the USA! This system also comes with extended sway bar links to maintain the sway bar angle and control body roll. Brake line relocation brackets make the job easy to do at home. New heavy duty lower control arms are supplied to correct alignment as well as axle location. The lower control arms are made from 1-3/4" OD x 1/4" thick wall D.O.M. tubing. The greasable urethane ends are dual fluted to allow for proper lubrication and long term performance. The rear is lifted via a new long add-a-leaf that will hold up without creating a harsh ride. In addition to the add-a-leaf kit, a new greasable extended shackle is supplied to gain additional lift and allow your springs to really flex. Zone shocks are included in the kit that are valved to perform both on and off road.Front coil springs designed to give a 4.5? of lift while maintaining an factory style ride Only 2? bump stop extensions are included because our springs are designed for extreme travel.
