I replaced my existing aftermarket billit aluminum end links with this set up because one of the bearings had failed, making a "click" in my front suspension. I replaced it with a known brand, arguably the best in the business. Baja Ron. It looks great! The installation was easy. The performance is as expected. It works good, it stiffened up a bit. Ten fold better than stock. I have piece of mind knowing that I got the best that I can get, with the links, and now the bar.
