High-lift camshafts and high-RPM operation place extreme stress loads on the cam caps of the RB26DETT — far beyond what the factory studs were designed to handle. The Tomei Cam Cap Stud Set (TA505A-NS05A) is the professional solution, replacing the stock bolts with high-strength Chrome Moly Alloy studs and nuts engineered to safely support cam lift profiles up to 12.0mm and engine speeds reaching 10,000 RPM. This upgrade eliminates the risk of stud stretch, thread damage, or cap lift that can occur with the original hardware under aggressive valvetrain loads.
Tomei’s precision-manufactured studs provide superior clamping force and consistent torque retention, ensuring the cam caps remain securely in place even during the most demanding track sessions or high-rev street driving. This added security allows engine builders to confidently push the RB26DETT to higher power levels and rev ranges without worrying about valvetrain failure. The complete set includes everything needed for a full cam cap upgrade, making it a critical reliability component for serious performance builds.
At Terra Firma Automotive, we supply this genuine Tomei Cam Cap Stud Set as the trusted choice for RB26DETT enthusiasts and professional builders who demand the highest level of valvetrain security. Whether you’re running aggressive cam profiles for circuit, drag, or street use, these studs deliver the strength and peace of mind required to safely extract maximum performance from your Skyline GT-R engine. This is one of those essential upgrades that serious builders install once and never worry about again.
