This kit is a complete replacement for the upright bolt in High Tensile (10.0) Zinc Plated.

Certainly when doing trackdays or even racing the car, we would recommend to replace these bolts every year.
Better be safe than sorry.. if these break, you'll experience a very special steering behaviour :)

We recommend to use 8.8 bolts in this application. Certainly with Aluminium uprights 10.9 will strip the thread inside the upright when torquing them up!
