One of the main suspension components on 4wd Bronco’s and F-150’s to upgrade is the radius arms. The stock versions are too short, stamped from sheet metal and pivot on a rubber bushing. Our radius arms are considerably longer in length to allow for more wheel travel and an improved camber curve. We also build more caster into the arm for better straight line stability and cornering precision. We use a Made in the USA FK 1-1/4″ heim joint with our new mounting brackets. This eliminates flex and also allows for more wheel travel. We build these using thick 3/8″ plate top and bottom and 1.75″ 4130 chromoly tubing that is boxed in for maximum strength. Many competitors use smaller, thinner and cheaper materials for a cheaper, lighter duty part. These were designed and built to be raced on and have been over the last 15+ years.
You can use these with either a coil spring or a coilover setup. We don’t weld on shock mounts, but do supply you tabs if they are needed. These are designed to be used with a 4″-6″ increased ride height over stock. To install these you will need to drill 1/2″ holes in the frame rails. All necessary hardware is included. These come raw so that you’re able to weld on them if need be or have powder-coated/painted the color of your choice.
