We have been racing with these Boxed Chromoly Tig Welded A Arms for over 3 years without 1 failure. Our A Arms replace all of the weak links. Upgraded Delrin Bushing sleeves, Chromoly Nylafiber Race Rod ends matched with our Stainless Steel Balljoint Stud Replacements. All TIG Welded and ready to Race OR Play. A ton of companies keep the stock balljoints in the ARMS!!!!! Why spend that much money just to have the same weak link that breaks? You will never have to worry about another Balljoint failure again? Just think about this, if a balljoint fails while driving it typically breaks over $1k in parts and leaves you stranded in the desert for hours. Don't be cheap be smart.
