They are 24% stronger than the Dilivar and have been designed to handle the thermal expansion… These are much stronger head studs, without the brittleness (of Dilivar). Tuners going for high power with the 911 based engines have had problems with the Dilivar head studs stretching and breaking… A good solution is the new head studs offered by RACEWARE ™ Engineering.
RACEWARE ™ Aerospace Quality engine fasteners are the performance advantage that professional racers depend on and you can too. Once you experience the quality and performance advantage of RACEWARE ™ Aerospace Quality engine fasteners, you will see why we are the gold standard in engine fasteners for the German engines. RACEWARE ™ is the only German engine fastener supplier to certify the performance of our fasteners to superior Aerospace Quality specifications.
RACEWARE ™ is the only company that has a stated Guaranteed Minimum Tensile Strength for our fasteners that is independently verified.
Independent testing by government accredited A2LA material testing labs that specialize in threaded fastener testing has shown that these claims are often meritless. Have you ever wondered about the performance claims that some companies make for their fasteners? You should. Without this knowledge it’s impossible to design the best fastener system for an engine, as demonstrated by the many failed fasteners people send us that were produced by other companies that simply lacked the engine expertise required. RACEWARE ™‘s 40 years of engine design and racing success allows us to understand the engine operating environment and the extreme changes that occur when an engine is started at -30° F and progresses to 300°+ F temperatures. Having designed new engines for the car makers for many years, RACEWARE ™ has the technical expertise to properly engineer a superior fastener solution for a specific automotive application. It’s far more involved than just using a quality alloy steel and rolled threads. Results are what counts, not advertising claims and RACEWARE ™ 205,000 PSI tensile strength Aerospace Quality engine fasteners have proven to be the best fasteners for the German engines, bar none, and our customers have proven this countless times!ĭesigning and manufacturing the best Aerospace Quality engine fasteners for the German engines takes expertise that other companies lack. The other fastener brands may look similar to RACEWARE ™ but history and independent lab testing has shown that that the other brands don’t perform the same as RACEWARE ™ Aerospace Quality engine fasteners because they lack the superior engineering designed into every RACEWARE ™ fastener. They ended up replacing those highly advertised aftermarket head stud kits with a genuine RACEWARE ™ head stud kit to permanently eliminate head gasket leaks in their engines.
This has been proven over and over by engine builders and auto enthusiasts who purchased other brands of head stud kits only to experience chronic head gasket leaks.
Note : RACEWARE™ cylinder head stud kits are able to prevent head gasket leaks that other highly marketed brands of engine fasteners cannot. RACEWARE™ Head Stud Kits Protect Your Engine from Expensive Damage
