ARP Cylinder Head Stud Kit- BMW E46 M3 Z3 M Z4 M Coupe & Roadsters with S54 Engine
For high performance and racing engines we strongly recommend upgrading from OEM stretch type cylinder head bolts to an ARP2000 Cylinder Head Stud kit to help your S54 engine maintain an optimum cylinder head to block seal, even under the most extreme conditions. That's why we use ARP hardware in any area it is available for every engine we build. ARP2000 is capable of achieving a clamp load at 220,000 psi. ARP2000 is used widely in all types of racing with tremendous results.
Following heat-treat, each stud is centerless ground to make it as close to perfectly concentric as possible. Its important to note because lesser quality stud are not centerless ground, but thread-rolled in bar stock form(mostly before heat-treat, when the material is easier to machine). ARP studs are thread rolled after heat-treat, which gives them about 1000%(that's ten times) better fatigue strength than those rolled prior to heat-treat. Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned - something that you'll never experience with inferior quality head studs.
ARP’s customer list includes the “who’s who” of motorsports from around the world. In the past several years, virtually every major championship on the planet has been won with engines prepared by ARP customers. These include NASCAR Sprint Cup, IndyCar, Formula 1, ALMS, NHRA Top Fuel, Funny Car & Pro Stock, NASCAR Nationwide Series and Camping World Truck Series. And so it goes. ARP works closely with many, many teams as a supplier of engine and driveline fasteners, and has clearly become recognized as “the” preeminent source for serious racers.
In addition to its core automotive business, ARP has an Aerospace Division, and is one of the very few companies in the world fully licensed by the United States Government to manufacture MS-21250 fatigue rated fasteners.
