BDS Front Long Radius Arm 4 Link Upgrade Kit for F250 F350 Super Duty 2-4 Lift. BDS 123251 Frt Radius Arm Upgrade Box Kit for F250 F350 Super Duty w/ 2-4 Lift. PART NUMBER: 123251 BRAND: BDS Suspension. The new Super Duty radius arms can be an upgrade for the Ford F250/F350 with 2-4 of front lift.
They cannot be used with radius arm drop brackets at these heights. Therefore, if someone has a current BDS radius arm drop bracket kit, they will need to remove the drop bracket to install these arms.
For those with 6 of front lift, the radius arms can be installed with the drop brackets as a direct swap for the factory radius arms - only caution would be that the caster may need to be checked if ball joint cams are installed. These new arms use the factory mounting hardware at the frame and a combo of factory and provided hardware with cam locks at the axle. Designed to work with: 35 x 12.50 x 17(18)(20) Tire. Engineered with high dimensional accuracy for the perfect fit.
Made from durable materials to survive the test of time. Built to meet strict international quality standards.
High-end performance at an affordable price. Radius Arm Box Kit - DRV. Radius Arm Assembly - DRV Side. Superduty Radius Arm 2"-4". M18-2.5 x 150 Bolt.
