Early Bronco Radius Arm Showdown – Duff vs Solo vs Tom’s vs Stock!

In this video, we compare four different Early Bronco radius arms: James Duff, Solo Motorsports, Tom’s Bronco Parts, and the factory Ford arms. We walk through weight, caster, length, tire clearance, bushings, and price to see how these arms stack up. We’ll be running these arms on our race truck and pre-runner builds as we prep for the King of the Hammers—so this isn’t just talk. Everything here is headed for real-world testing. If you’ve ever wondered which radius arm is worth your money—or if stock arms still hold their own—this breakdown is for you. 📊 Radius Arm Comparison Factory Ford • Caster: 0° • Weight: 15.6 lb • Length Added: 0" • Tire Clearance: 0.5" • Price: Free (if you can find them!)
