Radius Arm Bracket Pair

Adjustable radius arm brackets for 2" x .25" lower arms and 7/8" upper heims.

This bracket setup is a modern take on a well-proven design. Radius arm suspensions have been around for decades—originally adapted from early 4-link designs and proven across everything from Ford trucks to full-blown trail rigs. What makes these different is the built-in adjustability. Whether you're dialing in suspension geometry or compensating for larger tires, these brackets help you keep your caster and steering angles in check without rebuilding your front end.

Designed to mount on 2" x .25" wall lower links, they use a 7/8" heim joint at the upper position. The upper bracket has a 1 5/8" mounting width and is drilled for a 9/16" bolt. A solid setup for builders who want long-travel articulation and fine-tuned handling without compromising strength. Sold in pairs.
