We use Moog and TRW steering and suspension parts.  You can tell the difference just by comparing their part from another cheap part JUST BY LOOKING.   Next time you need a ball joint, ask to look at both a Moog or TRW one and one out of a plain white box.  You can see the difference in quality. Besides, most all the parts we buy have a lifetime warranty and that gives our customers the best warranty we can provide.  This is an area where price and quality go hand in hand.
