ARP is now the official Head Stud of NHRDA
Since ARP head studs are the de facto standard for today's diesel engines, it only makes sense for ARP to be the official head stud of the National Hot Rod Diesel Association. NHRDA competitors are continually pushing the limits of power and torque that diesel engines can generate and they use ARP to keep the heads on.
