Important Notes

• Fits models with 3.0L Hurricane I6, 3.6L V6, and 5.7L V8 engines.
• Extreme care and caution must be taken to follow the steps of the installation instructions to prevent any air leaks or damage to the air bags during installation.
• The factory air ride is a closed-loop system. Opening the system more times than recommended in the lift instructions will require the system to be recharged (this can be done at any RAM dealer service department). A scan tool is needed to access the air control module to perform the service.
• Frame bracket modification is required.
• Fits 4WD models equipped with factory air ride only.
• Stock 18-inch wheels cannot be reinstalled due to steering interference. Stock 20-inch and larger wheels can be reinstalled with factory-size tires.
• Trucks equipped with factory 22-inch wheels must use the Large Bore steering knuckles (reference build code WPM or WPZ, or check the diff cover for cooling lines).
• Does NOT fit Diesel models.
• Will NOT fit models equipped with the Thermal Axle option. Reference build code DSK-P or check the diff cover for cooling lines mounted.
• If using 18-inch wheels with maximum recommended backspacing, test fit wheels on the vehicle before mounting tires to ensure clearance.
• Included replacement front brake lines (22545) do not work on 2025 model year trucks; a relocation bracket is used instead. See instructions for bracket details.
