Overall Assessment

Customers applaud our radius arms for their excellent build quality and fit, praising their strength and practicality above competitors' offerings. These rods are highly commended for their suitability for diverse projects, particular mention given to their perfect match with vintage car models. The arms' welding quality is highlighted, with many customers willing to re-purchase. Minor modifications may be needed but the product's overall strength, usability, and beneficial attributes, such as the "rolling bones" feature, make it a standout choice. Despite some marginal welding aesthetics, the product's functions are unimpaired.

Excellent radius arms!

I added these radius arms to my 1935 Dodge rat rod where the previous wishbones had been hole cut to match the frame. They were not sturdy enough for a bad Kansas pothole and bent enough to cause death wobble over 40mph. These radius arms came in very fast and matched my set perfectly. They are well built with good welds and overall excellent build quality. I would recommend these to anyone running a suicide drop I beam axle!
