ZOND40LN / D41LN 6" Lift Kit improves ground clearance, stance, and off-road capability on 2013–2018 Ram 1500 4x4 trucks while maintaining factory ride quality and drivability. Engineered to OE standards, this system allows for up to 37" tire fitment while properly correcting suspension, steering, and driveline geometry for stable performance both on-road and off-road.
This configuration includes pre-assembled Zone Nitro loaded front struts paired with Zone Nitro Series rear shocks, delivering a complete suspension solution with smooth, reliable damping and straightforward bolt-on installation. High-strength, USA-cast steering knuckles maintain proper steering geometry and alignment, while heavy-duty crossmembers, differential drop components, and a skid plate improve durability and underbody protection in demanding conditions.
In the rear, this kit is equipped with 3" coil springs designed to provide a level stance while maintaining ride quality and load capacity. These progressive-rate springs are engineered to handle varying loads without sacrificing comfort, making them ideal for both daily driving and off-road use.
Built with durable, powder-coated components and designed for long-term reliability, this lift kit provides a well-balanced upgrade for drivers looking to enhance both performance and appearance while maintaining everyday usability.

Important Notes
Does NOT work with All Wheel Drive (AWD) models.
This kit is not recommended for TRX models. CV shaft vibration will occur on TRX models unless the TRX struts are replaced with standard struts. Instead, consider Zone's 4" lift system for about 5" of TRX lift.
Will NOT fit adjustable air suspension (air-ride) equipped models. Fitment: Does not fit eco-diesel models. The front drive shaft WILL fail prematurely.
These trucks are typically between 1" and 3" tail high from the factory. Please measure your truck's factory front-to-back ride height and order the rear lift height to achieve the desired stance. If closer to 1" tail high from the factory, order the 5" rear coils for a more level stance. If closer to 3" tail high from the factory, order the 3" rear coils for a more level stance.
