Description

Lift your 2025 to 2026 RAM 1500 with factory air ride suspension using the BDS 4" Lift Kit, engineered for enhanced performance, improved ground clearance, and an aggressive stance without compromising ride quality. This premium system is designed specifically for air ride-equipped models, ensuring proper integration with factory components and maintaining full air ride functionality. With a full 4 inches of front lift, this kit allows clearance for up to 35-inch tires, giving your truck a more commanding presence and increased off-road capability. The kit includes high-strength crossmembers, heavy-duty steering knuckles, differential relocation brackets, sway bar links, and all necessary hardware to ensure a reliable and precise fit. For rear shock options, you can choose between FOX 2.0 Performance Series IFP shocks, ideal for those seeking fade-free, high-performance damping on and off the road, or BDS NX2 Nitro Series shocks, which offer excellent control and comfort at a more budget-friendly price. Compatible with 2025 to 2026 RAM 1500 models equipped with factory air ride (excluding TRX models), this kit is backed by the industry-leading BDS No Fine Print Warranty, giving you the confidence to take your truck further on pavement, dirt, or wherever the road ends.

Important Notes

  1. Fits models with 3.0L Hurricane I6, 3.6L V6, and 5.7L V8 engines.
  2. Extreme care/caution must be taken to follow the steps of these instructions to prevent any air leaks or damage to the bags during installation.
  3. 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.
  4. Frame bracket modification is required.
  5. Fits 4WD models equipped with factory air ride only.
  6. Stock 18" wheels cannot be reinstalled due to steering interference. Stock 20"+ wheels can be reinstalled with factory-size tires.
  7. Trucks equipped with factory 22" wheels must use the large bore steering knuckles.
  8. Does NOT fit Diesel Models.
  9. Will NOT fit models equipped with the Thermal Axle option. Reference build code DSK-P or check the diff cover for cooling lines mounted.
  10. IF USING 18IN WHEELS WITH MAXIMUM RECOMMENDED BACKSPACING, TEST FIT WHEELS ON VEHICLE BEFORE MOUNTING TIRES TO ENSURE CLEARANCE
  11. Included Replacement front brake lines (22545) do not work on 2025 model year trucks, relocation bracket is used instead. See instructions for bracket details
