2019-2025 Ram HD 4.5-6" Tubular Radius Arms (77-19000)

The ReadyLIFT Tubular Radius Arm Upgrade Kit for the 2019-2025 Ram 2500/3500 is a heavy-duty suspension solution engineered to handle the rigorous demands of lifted Ram HD trucks. These radius arms serve as critical alignment components, correcting suspension geometry and caster angles on trucks with 4.5 to 6.0 inches of lift. Formed inward to provide additional tire clearance, these arms allow for larger wheel and tire combinations while utilizing oversized rubber bushings to better isolate road noise and vibration for a superior ride experience.

Features

• Heavy-duty tubular steel construction designed for maximum durability and off-road abuse.
• Corrects suspension geometry on trucks with lift heights between 4.5 and 6.0 inches.
• Optimizes the caster angle to improve steering feel and tracking on lifted models.
• Radius arms are formed inward to provide extra clearance for wider, oversized tires.
• Equipped with oversized rubber bushings to isolate road noise and reduce vibration harshness.
• Provides a much cleaner and more professional look compared to radius arm drop brackets.
• Direct bolt-on design facilitates a straightforward installation process without permanent modifications.

Notes

• A professional wheel alignment is required after installation to ensure optimal steering and tire wear.
• Headlamp aim must be checked and adjusted for safety following any changes to the vehicle's height.
• Advanced Driver Assistance Systems (ADAS) should be recalibrated to maintain proper monitoring and function.
• Installation by a certified mechanic is recommended due to the significant labor time (est. 12 hours) and complexity.
• Can be used to replace radius arm drop brackets in existing 4.5" to 6" lift kits for a cleaner aesthetic and better ride.

Compatibility Notes

• Fits 2019–2025 Ram 2500 and 3500 4WD Heavy Duty models.
• Specifically designed for vehicles with 4.5 inches to 6.0 inches of front lift.
• Compatible with ReadyLIFT lift kits (like 49-1960 and 49-1961) by removing the radius arm drop brackets.
