About this product
Correct Radius Arm Angle on Your Leveled Super Duty
APOC Industries radius arm drop brackets fit 2005–2022 Ford F-250 and F-350 Super Duty 4WD trucks with 2–4 inch leveling kits or suspension lifts, including gas and diesel models. This driver- and passenger-side set lowers the rear radius arm mounting points at the frame, allowing you to keep your existing radius arms while correcting their angle.
How These Brackets Help
Raising the front changes radius arm geometry and can reduce caster. These brackets add positive caster and help move the front axle forward toward its factory position, addressing steering wander associated with lift-induced caster loss. They are not a substitute for diagnosing worn steering or suspension components.
Construction & Features
- Laser-cut 1/4" steel plate construction.
- Powder-coated finish.
- Relocates the frame-side radius arm pivot downward.
- Helps restore axle position and adds positive caster on compatible 2–4 inch lifted setups.

Installation & Clearance Notes
The brackets nest inside the factory radius arm frame brackets and use the existing mounting holes. In some cases, the uppermost forward factory hole may require light reaming to accept the supplied 3/4" bolt. Remove only the minimum material needed for a snug fit; do not enlarge the hole beyond the guide's instructions.
Both frame-side radius arm pivot bolts must be removed as described in the guide so the axle and arms can move together. Follow the complete support, installation, and torque procedures before beginning work.
- Tools include appropriate vehicle-support equipment, sockets, a torque wrench, and potentially a reamer or round file.
- Check clearance through suspension travel and have front-end alignment checked after suspension work.
- Recheck fastener torque after 50–100 miles and inspect hardware during routine service.
