{"product_id":"4-inch-lift-kit-with-radius-arms","title":"4 Inch Lift Kit with Radius Arms","description":"Give your 2020-2022 Ford F-450 the lift it deserves with the BDS 4\" Radius Arm Lift Kit. This system is an ideal choice for drivers seeking strength, simplicity, and outstanding everyday performance. While 4-link systems offer excellent articulation, this radius-arm setup excels in durability, straightforward design, and long-term reliability, qualities highly valued on heavy-duty trucks.\n\nThe BDS heavy-duty radius arms are constructed from DOM steel and mount into the factory location, offering caster adjustment for various lift heights. They feature OE-style rubber bushings at the frame mounts to isolate noise and vibration, providing a smoother, quieter ride without requiring ongoing maintenance. The kit includes full-length Pro-Ride coil springs to achieve the correct lift height and deliver a smooth, predictable ride. For steering correction, a forged drop pitman arm is included to minimize steering angle, paired with a heavy-duty track bar drop bracket to maintain axle alignment through suspension travel.\n\nThis kit is compatible with 37 x 12.5 tires when paired with 18x9 or 20x10 wheels with appropriate backspacing (trimming may be required). Buyers can choose from several shock options to complement the lift kit: the BDS NX2 Nitro Series shocks (nitrogen-charged, twin-tube), the FOX 2.0 Performance Series (2-inch impact extruded aluminum body, IFP monotube), or the FOX 2.5 Performance Elite Series with DSC (Dual Speed Compression) adjusters for tunable control. The system can also be optioned with front FOX 2.5 Performance Elite coilovers for maximum responsiveness and comfort. The BDS radius arms restore proper caster angle and axle alignment, aiding in predictable steering, stable handling, and preventing wander or tire wear.","brand":"BDS Suspension","offers":[{"title":"Default Title","offer_id":52867478028600,"sku":"BDS1224FPE","price":5092.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687943870.webp?v=1787911260","url":"https:\/\/store.motormia.co\/products\/4-inch-lift-kit-with-radius-arms","provider":"MOTORMIA","version":"1.0","type":"link"}
