ARP head studs are the de facto standard for today’s diesel engines. ARP’s product line contains thousands of part numbers, and has expanded to include virtually every fastener found in an engine and driveline and throughout the suspension and frame. These range from quality high performance OEM replacement parts to exotic specialty hardware for Formula 1, IndyCar, NASCAR and NHRA drag racing and marine applications. If you are pushing the limits of power and torque that diesel engines can generate then ARP is what you need to keep the heads on.
