"We are excited about our continued partnership with the DIESEL Motorsports race and pulling series," stated Chris Raschke, "In addition to being a premiere sanctioning series for competitive Diesel racing and pulling; it is an ideal proving ground for our diesel engine technology." Raschke added, "the diesel market is huge for us and by leveraging the exposure of the series and the fact that many are multi–use vehicles. We feel we can reach not only the diesel competitor but also the towing and fuel economy diesel market. By being an official product of DIESEL Motorsports we hope to create awareness about our exciting technology and the big benefits for diesels."

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.
