Dorman - OE Solutions Radius Arm P/N:522-389
Keep the front axle firmly located and control fore-aft movement with the Dorman - OE Solutions Radius Arm (MPN 522-915). This is the front left radius arm, and it drops in as a direct-fit replacement for the 1999-2019 Ford F-250 Super Duty and 1999-2019 Ford F-350 Super Duty. See the Buyer's Guide tab for engine-level details.
A radius arm links the front axle to the frame, resisting the twisting loads of braking and acceleration while helping maintain axle position and caster. If a worn or damaged radius arm is behind clunking, front-end wander, or shifting caster on your Super Duty, this replaces it.
Consult the vehicle service information for the correct fasteners and whether they may be reused.
