Purchased to replace levers and tie rods on a 2001 Audi A6 Quattro. Aluminum parts, good quality. They appear to be a bit heavier than the OEM units but they are true to size and fit perfectly. Although fasteners are included, if you live in a place with salty roads in winter, don't use fasteners to resist corrosion. The coating applied to it is not of excellent quality. While it will prevent rusting during shipping, it most likely won't last long. Be sure to use anti-seize compound when installing the tie bolts.
