The Rusty's 3-inch XJ Suspension Kit is one the most successful items we have ever developed. Our soft spring rates along with our shocks valved specifically for this application have put this kit above the rest. All of the Rusty's 3-inch kits will clear 31 inch tires. Rusty's offers two front coil spring rates, either 150 lbs or 180lbs. The 180lbs springs provide the same amount of lift but will be able to handle the extra weight from a big bumper, winch, or a snow plow. Rusty's hydro shocks round out the components included with this kit, which will ride great and keep the tires on the ground! The Rusty's 3.5" rear spring packs have 5 leafs for a great ride and superior flex. The 3.5 rear springs are used in the kit to give you the load capacity for camping and outdoor gear for those much needed outdoor adventures and if you are building for wheeling, it gives you the extra load capacity for tools, spare parts, and over sized spare tire. If we didn't build this rear spring to use in this kit , once you loaded the vehicle for your trip , the rear end would be dragging the ground. The 5 leaf springs will give you the extra load capacity needed, yet gives you a smooth ride , loaded or un loaded. If you want the vehicle more level and will not be using to carry a load, a .75 poly coil spring spacer can be used on top of the front coil springs to more level the vehicle. Grade eight U-bolts fasten the springs to the axle. A rear brake line extension bracket is also included. Our Rusty's hydro shocks give you a great ride and keeps the tires on the ground.
