These RockJock front coil springs provide a 3.5-inch lift for JL Wrangler applications equipped with EcoDiesel, 392 Hemi or 4XE powertrains and for JT Gladiators with the 3.6L gas engine. They directly replace factory front springs, are finished in gloss black powder coat and were rate-optimized to deliver comfortable on-road ride quality and improved off-road performance when used with RockJock Johnny Joint systems or compatible lift kits.
