Our rods are machined from a solid piece of 1.25 Billet hex aluminum. That's right one and a quarter inch of solid Billet aluminum. These rods are larger than majority of similar products on the market, and sure to stand up to the abuse. Our radius rods are then hard coat anodized then they receive all 304 stainless jamb nuts for anti corrosion and heavy duty 5/8 chromoly heims. We also machine our own misalignment spacers from a solid bar stock of 304 stainless, giving you the highest quality fit and finish possible.
