Elevate your 2025-2026 RAM 1500 HO with the BDS 4" Lift Kit, purpose-built for air ride suspension systems. Experience the perfect balance of commanding presence and refined comfort as this engineered solution delivers increased ground clearance and a bold aesthetic while preserving your factory air ride's superior ride quality. Specifically calibrated for air ride-equipped models, it integrates seamlessly with OEM components and maintains full suspension functionality, giving you the aggressive stance you want without sacrificing the smooth handling you deserve.

IMPORTANT NOTES

Due to the complexity of your Rams factory air ride system we highly recommend using an experienced suspension specialist for installation. For help locating a specialist in your area please use our dealer locator or contact us. For information regarding the installation of this system and modifying your Ram's factory air-ride suspension check out our step by step instructions and the helpful tips video.

The Rack and Pinion steering system is extremely sensitive to an out-of-round or out-of-balance tire/wheel combination. As you increase the tire diameter and/or decrease the wheel backspacing the more sensitive the system becomes and can cause minor steering wheel shimmy.

It Fits factory air ride-equipped trucks only.

The factory air ride is a closed-loop system. Opening the system more times than recommended in the lift instructions or factory service manual will require the system to be recharged. This can be done at any Ram dealer service department.

Stock 20" wheels can be reinstalled with factory-sized tires only. Stock 17" and 18" wheels will not fit.

This kit will bolt on Eco-Diesel models but it will require an aftermarket front drive shaft.

If your vehicle has been modified with new leaf springs, the u-bolts with the Rear Spacer Block Kits may not be long enough. This lift kit is sold under the provision that the rear suspension has not yet been altered. If you need longer u-bolts, you may need to take the measurements and source some alternatives.
