Control Arm []

The BDS Suspension Radius Arm Upgrade (BDS122321) is engineered to bolster the front suspension of lifted Ram trucks, addressing a common weak point found in factory stamped radius arms. Constructed from robust 1.75-inch OD steel tubing and fortified with fully welded gussets, these arms provide significantly enhanced strength and resilience for demanding use. Designed specifically for 2014-2026 Ram 2500 and 2013-2024 Ram 3500 4WD models equipped with 2-6 inches of suspension lift, this upgrade is crucial for restoring proper suspension geometry and caster angles. By correcting these alignment parameters, the BDS Radius Arm Upgrade contributes to tighter steering response, more controlled suspension movement, and straighter tracking at highway speeds. Additionally, it offers improved ground and tire clearance, particularly beneficial for trucks running larger aftermarket tires. The integration of OE-style rubber bushings ensures a quiet and comfortable ride by effectively isolating road noise and vibrations without requiring maintenance. The arms are finished with a durable textured black powder coat, providing excellent resistance against corrosion and trail damage. Installation is straightforward as a direct bolt-on replacement, requiring no cutting or welding. Important fitment notes include: This upgrade is designed for trucks already equipped with a 2-6" suspension lift and is not compatible with trucks running factory radius arms without a lift. An alignment may be required after installation to ensure optimal handling. This product is intended for 4WD models only.
