This bolt-on upgrade for 2005-2022 Ford Super Duty trucks replaces the weak stock radius arms with ultra-duty adjustable 3-link arms.

With both upper and lower arms adjustable, you can properly position the front axle and fine-tune caster—resulting in noticeably improved handling and steering precision, whether you’re stock height or lifted up to 7".

Built by hand in the USA with rebuildable, greaseable joints and full Grade-8 hardware, these arms are made to perform and last

Why Upgrade?

• Improved Strength — Eliminates the flex and weakness of stock radius arms and drop brackets for a more stable and responsive front end.
• Caster & Axle Position Control — Both arms adjust so you can fine-tune caster & axle placement for optimal alignment and drive feel up to 7" lift.
• Rebuildable & Greaseable Joints — Less maintenance cost, quieter operation, better durability over time.
• Finish Options — Choose between Semi-Gloss Black Wrinkle Powder Coat or Bare Steel to match your setup or aesthetic preferences.
• Full Hardware Included — All Grade 8 fasteners supplied for reliable fitment and strength.
• Clean Installation — For lifted trucks using radius arm drop brackets, this replaces both the bracket and radius arm for a neater, more durable setup.

Fitment & Compatibility

• Fits Ford Super Duty 2005-2022 (F-250, F-350, F-450)
• Works with stock or lifted trucks up to 7″ lift
• Can be paired with PMF radius arm drop brackets for greater lift heights
