The ARTEC RB26DETT 625 Inconel Exhaust Stud Kit was developed after identifying a common issue with many aftermarket stud kits currently available for the RB26 platform. During development, we found that many replacement studs did not utilise the full thread depth available in the OEM Nissan cylinder head, leaving valuable thread engagement unused. By increasing the amount of engaged thread, clamping loads can be distributed more effectively while making full use of the factory casting. Features: Manufactured from premium 625 Inconel Designed specifically for the Nissan RB26DETT Maximises thread engagement within the OEM cylinder head Utilises the full available thread depth machined by Nissan Designed for extreme exhaust manifold and turbocharger temperatures Excellent resistance to heat, oxidation and corrosion Suitable for high-performance and motorsport applications Package Contents: 12 x M8x1.25 Inconel 625 Studs 12 x M8 Nord Lock Washers 12 x M8 Copper Locking Nuts
