Front: Zone Nitro loaded struts come preassembled for easy installation (Strut Replacement method, 4" front lift height). Rear: Zone Nitro twin-tube rear shocks paired with a 2-inch coil spacer (2" rear lift height). Overall lift range: 4–5.5". Nitro shocks feature nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends, self-lubricating seals, and a 2-inch diameter steel body with black powder coat finish.
Overview
The Zone Offroad 4-inch Lift Kit for 2013–2018 Ram 1500 4x4 trucks delivers aggressive stance, larger tire clearance, and OE-quality engineering for both on- and off-road performance. Designed by Zone Offroad engineers in Coldwater, Michigan to OE standards, this system features heavy-duty steering knuckles cast in the USA, while all fabricated steel components are locally manufactured and powder coated for long-lasting durability and corrosion resistance. The 4-inch lift allows clearance for up to 35 x 12.50 tires on wheels with 4.5 inches of backspacing. Multiple configuration options are available: up front, choose OE strut spacers that retain the factory struts, or opt for Zone Nitro loaded struts that arrive preassembled for simplified installation. In the rear, select a 2-inch coil spacer to level the truck front to rear, or 3-inch replacement coil springs to retain some factory rake. Rear shock options include Zone Nitro twin-tube shocks or FOX 2.0 Adventure Series shocks for improved performance.
