Our Land Rover radius arms are about 40 inches long, allowing the front and rear arms to nearly meet in the middle of our flatfender frame. This is a huge advantage because it places most of the suspension stresses on the strongest part of the frame. Heavy-wall tubing pierces both sides of the frame, creating a mounting boss for each radius arm. The arms are cinched in place with 5⁄8-inch bolts. A double-shear plate will be added to the outside of these arms to help prevent the bolts from shearing off or bending.
