4-Inch Radius Arm Lift Kit

The BDS Suspension extended travel 4-inch radius arm lift kit is engineered for Diesel-powered 2025-2026 4WD Ram 3500 trucks. This comprehensive system enhances ride quality, handling, and off-road performance without compromising everyday drivability or on-road comfort. It allows for the fitment of up to 37-inch tires, providing a more aggressive stance while ensuring proper driveline angles. Heavy-duty replacement radius arms are crucial for repositioning the front axle and correcting caster angles, which improves straight-line stability, steering return-to-center, and braking control. These radius arms are reinforced for added strength and durability. A heavy-duty track bar bracket is also included to center the front axle and maintain precise steering geometry. Furthermore, a 10-bolt transfer case indexing ring is provided to optimize driveline angles and increase suspension droop, enhancing off-road capability beyond that of basic lift kits. Customers can select from various shock options to tailor the suspension's performance, including BDS NX2 Nitro shocks for daily driving and light off-road use, FOX 2.0 Performance Series IFP shocks for consistent performance, FOX 2.5 Performance Series IFP shocks for enhanced damping in rough terrain, and FOX 2.5 Performance Elite Series shocks with DSC adjusters for race-inspired tunability. In the rear, lift is achieved through a high-strength fabricated lift block and longer U-bolts. The kit also includes sway bar links and brake line brackets. Features and benefits include extended travel shocks with a transfer case indexing ring, heavy-duty tubular radius arms for improved strength and handling, front high-strength dual-rate coil springs for a comfortable ride, a forged front adjustable track bar to re-center the axle, and front sway bar correction for optimal handling. This lift kit is built with BDS Suspension’s commitment to strength, ride quality, and long-term reliability, making it an ideal upgrade for Ram 3500 owners seeking enhanced performance and capability.
