RCM Extreme 11mm Cylinder Head Stud Kit EJ20/22/25 (TS – 237,000psi) RCM1540

Description

Part Number: RCM1540

Now used in many of the fastest and most powerful Impreza’s across the globe the RCM 14/12mm Head Stud Kit is quite simply the foundation on which many of our high bhp engine conversions are built around. Replacing the conventional 11mm Subaru cylinder head bolts with a series of 14/12mm 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 successful 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.
