The Zone Offroad 6-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 our team of engineers in Coldwater, Michigan to OE standards, this system features heavy-duty steering knuckles that are cast in the USA, while all fabricated steel components are locally manufactured and powder coated for long-lasting durability and corrosion resistance. The 6-inch lift allows clearance for up to 37 x 12.50 tires on wheels with 4.5 inches of backspacing, giving your Ram a commanding presence and enhanced capability. This kit also offers multiple configuration options to fit your build. Up front, you can choose OE strut spacers that retain the factory front struts and pair them with either Zone Nitro twin-tube rear shocks or upgrade to FOX 2.0 Adventure Series rear shocks for improved performance. For a complete bolt-in solution, Zone Nitro loaded struts are also available and come preassembled for easy installation, matched with Zone Nitro rear shocks. In the rear, you can select a 3-inch block to level the truck from front to rear or a 5-inch block to retain most of the factory rake, allowing you to tailor the stance and functionality of your lifted Ram.

Important notes before you order
- 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 our 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. Front drive shaft WILL fail prematurely.
- These trucks are typically between 1" and 3" tail high from the factory. Please measure your trucks 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.
- Stock 17" wheels CAN NOT be re-installed.
- Stock 20" can be re-installed with factory tire.
TRU specialist notes
From the Trucks R Us fitment and install team, beyond the manufacturer's information.
- Plan for a professional wheel alignment after installing any lift or leveling kit.
- Going to bigger tires as well? Speedometer recalibration may be needed, and some tire and wheel combinations need trimming. Check the recommended wheels and tires, or ask us before you order.
