What Radius Arms Do
The rear radius arms (also called radius rods) run from the frame to the rear knuckles and keep the rear wheels tracking straight and at the right camber as the suspension moves. They sit low, right where rocks and stumps hit, so a bent stock arm is a common trail failure. A bent arm throws off rear alignment, causing the machine to pull, scrub tires and handle unpredictably.
Why Billet Aluminum
Billet aluminum is machined from a solid block, so there are no welds to crack and the shape can be optimized for strength. 6061 has an excellent strength-to-weight ratio, meaning the arms are tougher than stock while cutting unsprung weight, which helps the rear suspension react faster over bumps.
Adjustable for Your Setup
The 5/8" heim joints let you fine-tune length to set rear alignment, which is useful after adding a lift, different trailing arms or bigger tires.
