ARP SeaDoo RXP-X255 Engine Head Stud Kit

This kit from ARP gives you everything you need to properly secure the cylinder head on your SeaDoo RXP-X255. You'll get the high-strength head studs, along with the necessary nuts and washers, all made to ARP's exacting standards. When you're rebuilding the top end of an engine, especially one that sees high performance use like a SeaDoo PWC, ensuring the cylinder head stays firmly in place under pressure is critical for sealing and preventing leaks.

ARP studs are well-built from premium 8740 chromoly steel, heat-treated to achieve a tensile strength of 200,000 psi. This means they can handle the increased clamping forces required for high-performance applications, helping to prevent head gasket failure. Unlike stock head bolts, these studs allow for more consistent and accurate torque readings, which is crucial for achieving a proper seal between the cylinder head and the engine block. The threads are rolled after heat treatment, which makes them significantly stronger and more resistant to fatigue than threads that are cut.

This kit is designed as a direct replacement for your stock head bolts, making installation straightforward for anyone comfortable working on their engine. Using quality studs like these is a smart move when you're pushing your SeaDoo's engine to its limits, ensuring reliability and performance.
