2005–2022 Ford F-250/F-350 Super Duty Radius Arm Drop Brackets | 2–4 Inch Lift
2005–2022 Ford F-250/F-350 Super Duty Radius Arm Drop Brackets for 2–4 Inch Lifts
The Apoc Industries radius arm drop bracket kit is designed for 2005–2022 Ford F-250 and F-350 Super Duty 4WD trucks with 2–4 inch leveling kits or suspension lifts. Compatible with gas and diesel models, this driver- and passenger-side bracket set lowers the rear radius arm mounting points on the frame to correct radius arm angle, add caster, and move the front axle forward toward its factory position.
Have a Leveling Kit and Steering Wander?
Yes, these brackets help. A leveling kit changes the factory radius arm geometry. For leveling kits within the 2–4 inch range, these drop brackets help move the front axle forward toward its factory position and add positive caster to correct steering wander caused by reduced caster after leveling. This helps restore more stable, straight-line steering while keeping your existing radius arms.
These USA-made steel brackets offer a bolt-on solution without cutting or frame modification. A professional front-end alignment is required after installation. Steering wander caused by worn components or other issues still needs separate diagnosis and repair.

FAQ
Use this text to share information about your product or shipping policies.
Does this bracket improve caster angle?
Yes — one of the primary benefits of the APOC radius arm drop bracket is caster correction. When you lift a Ford F-250/350, the radius arms pull the axle rearward, reducing your caster angle. Low caster causes poor returnability, wandering on the highway, and unstable handling. This bracket restores proper caster geometry so your truck tracks straight and handles confidently at any speed.
How much caster does this bracket restore?
The APOC radius arm drop bracket is engineered to fully restore factory caster specs for 2–4" lift heights — and then some. You'll actually end up with slightly more positive caster than stock, which means better straight-line stability, improved steering returnability, and a more confident feel on the highway.
What are the symptoms of incorrect caster on a lifted truck?
Common symptoms include the steering wheel not returning to center after turns, the truck pulling to one side, highway wander, and increased steering effort. If you're experiencing these after a lift, caster correction is likely the fix.
