Product Description
Designed for the ultimate in engine performance and reliability and derived from the rigors of the World Rally Championship, RCM’s 14mm/14mm Head Stud Kit has consistently proven itself as a must have component of any EJ20/22/25 engine build where 500bhp+ power output is expected. It is essential engines modified to this level 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 14/14mm Head Stud kit provides this peace of mind! Now used in many of the fastest and most powerful Imprezas across the globe the RCM 14/14mm Head Stud Kit is quite simply the foundation on which all our high bhp engine conversions (including Gobstopper 1, 2 & 3) 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.
