Description
This heavy duty radius arm upgrade package features tough replacement radius arms that will work with most 4" - 6.5" suspension lifts. Made of fully boxed and internally gusseted 1/4" steel and utilizing large greasable urethane bushings, these arms are a considerable upgrade in strength from the stock arms. Holding true to typical Zone form, this lift system is centered around two new massive radius arms to replace the factory arms. The new arms are fully boxed, internally gusseted and designed to bolt in the factory location while adjusting the suspension geometry for 4.5" to 6.5" of lift. The arms utilize extra large, greaseable bushings at the frame and are designed to use the factory alignment cams at the axle. They are formed for maximum tire clearance. Lastly, they just flat-out look cool and are a nice upgrade from the standard radius arm drop systems. In the rear, the new 4 link suspension designed is modified for 2.5" of lift via a new heavy duty coil spring spacer setup. The coil spring spacers located and bolt directly to the factory axle mount. The new provided track bar relocation bracket centers the axle. Extended sway bar links and bump stops round out the rear kit components.
