Engine Components-911 Raceware Aircraft Head Nuts (24 -Nuts Only) 911/930/964/993


Welcome to RACEWARE™ Engineering, LLC


RACEWARE provides the finest Forged 12 Point Aircraft Style Head Nuts available to compliment our 205,000 PSI tensile strength head studs. Each nut has a unique special anti-friction coating to insure accurate tensioning of the RACEWARE Aerospace Quality Head Studs in your engine. Using a proper high-strength head nut is important as a lower tensile strength nut may not allow proper tensioning of the studs which can lead to stripped threads or cylinder head leaks.

These precision 12 point nuts are also very popular for dual-sparkplug 911 series engines because they provide the needed clearance to remove the lower sparkplugs.

To insure accurate clamp force on your Porsche 911/930/964/993 cylinder heads, we recommend the use of our CNC Machined, Hardened Cylinder Head Washers and Forged 12 Point Aircraft Style Nuts. Replace those rusty, old, OE nuts and washers for better engine cooling and reliability.
