LS1 Gen III Svänghjulsbultar ARP

In early 1970s, racing enthusiast Gary Holzapfel saw his friend break his engine due to failed bolts. At that time there were no better options for a private person. So Holzapfel took the plunge, used his many years of experience in the industry as a subcontractor to the aerospace industry and founded ARP (Automotive Racing Products).
Since then, ARP has grown from a garage in the back, to a leading manufacturer of components used worldwide over. Today, they have 7 premises with a combined area of nearly 19,000 square meters, where they handle forging, heat treatment, milling, quality control and packaging. 

ARP today has thousands of article numbers and is today a standard in engine construction. You don't talk about upgraded bolts anymore. You say that you have mounted ARP bolts.
