4-Inch Radius Arm Lift Kit

The BDS Suspension extended travel 4-inch Radius Arm Lift kit is specifically engineered for 2025-2026 Diesel-powered Ram 2500 trucks. It provides clearance for up to 37-inch tires, offering a more aggressive stance while ensuring proper driveline geometry and maintaining everyday drivability. Heavy-duty replacement radius arms are included to correctly position the front axle and restore caster angles lost during lifting. These arms improve straight-line stability, steering return-to-center, braking control, and overall ride quality, while their reinforced construction adds strength. A track bar relocation bracket is provided to center the front axle and maintain precise steering geometry. Additionally, a 10-bolt transfer case indexing ring clocks the transfer case for optimized driveline angles and increased suspension droop, featuring an advanced seal for superior performance under extreme conditions. In the rear, lift is achieved with Pro-Ride BDS coil springs, and matching rear shocks are included for balanced performance. Buyers can select from various shock options, including BDS NX2 Nitro, FOX 2.0 Performance Series IFP, FOX 2.5 Performance Series IFP, and the premium FOX 2.5 Performance Elite Series with Dual Speed Compression (DSC) adjusters for customizable damping. Key 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, a forged front adjustable track bar, and front sway bar correction. Recommended tire and wheel sizes include 35x12.5 with 18 or 20-inch wheels with 4.5-inch backspace, or 37x12.5 with 20-inch wheels and 5.625-inch backspace; trimming may be required.
