ZOND151LN / ZOND152LN 4" IFS Lift Kit improves ground clearance, stance, and off-road capability on Ram 1500 trucks while maintaining factory ride quality and drivability. Engineered specifically for newer Ram platforms, this system corrects suspension, steering, and driveline geometry to ensure confident handling both on-road and off-road while allowing clearance for up to 35" tires.
This configuration includes pre-assembled Zone Nitro loaded front struts paired with Zone Nitro Series rear shocks, delivering a complete suspension solution with smooth, consistent damping and easy bolt-on installation. High-strength CNC-machined steering knuckles correct steering geometry and maintain compatibility with factory systems, while heavy-duty crossmembers and a differential skid plate provide added strength and underbody protection in demanding conditions.
ZOND151LN features standard steering knuckles, while ZOND152LN includes large bore knuckles designed for vehicles equipped with larger factory wheel bearing assemblies. This ensures proper fitment and long-term reliability depending on the vehicle’s OE configuration.
In the rear, full replacement coil springs provide lift while maintaining ride quality and load capacity, delivering a balanced stance and dependable performance. Backed by Factory Protection Plus, this system offers long-term reliability and peace of mind for both daily driving and off-road use.
