Genuine Audi Track Rod End Nut For 8P S3 - WHT000785A

Genuine Audi Track Rod End Nut For 8P S3 - WHT000785A

Correct track rod end part number for 8P S3 models, using the domed nut is very important. Some aftermarket track rod ends come with a smaller, non domed nut that is NOT safe to use on S3's. 

You can also use part number WHT000785 on an S3, it will work the same. The only difference is the head size of the nut meaning you just use a smaller socket to install.
