RCM 14/14mm Superstud Cylinder Head Stud Kit
The latest evolution of our proven and hugely successful 14/14mm RCM Head Stud Kit designed for the ultimate in engine performance and reliability! Introducing the new RCM 14mm Superstud Head Stud Kit.
Our engineers have taken the ultimate EJ series head stud solution to the next level by incorporating some new features into the RCM 14mm Superstud kit to improve performance and ease of installation for your EJ engine.
• Larger 9/16" size stud (still compatible with RCM Head Gaskets)
• Supplied with x12 ARP 9/16" 8740 Chromoly 12pt nut
• Supplied with x12 ARP 9/16" 8740 Chromoly washer
• Incorporating 6mm hex in stud end for super easy install
It is essential engines modified to 500+bhp have the most reliable system for clamping the cylinder heads onto the block assembly to avoid the heads lifting under load at high levels of boost pressure. The RCM 14mm Superstud Head Stud kit provides this peace of mind!
Now used in many of the fastest and most powerful Imprezas across the globe the RCM 14mm Superstud Head Stud Kit is quite simply the foundation on which all our high bhp engine conversions (including Gobstopper and Gobstopper 2) race engines are built around. Replacing the conventional 11mm Subaru cylinder head bolts with a series of 14mm precisely manufactured super high tensile, aircraft grade S99 steel stud and nut system offers many advantages when building your engine. With a tensile strength much higher than that of the OE bolts and the increased stability provided by the RCM studs larger diameter when further combined with the more uniform clamping force provided by the stud and nut arrangement it is clear why so many championship winning engines run these kits!
All kits are supplied with RCM's own assembly lube, which utilizes Graphite DJ technology, ensuring you are able to install to the correct torque figures accurately.
