Wagner Tuning Burnished Head Stud Set for R35 Nissan GTR

The Wagner Tuning Burnished Head Stud Set for R35 Nissan GT-R is a motorsport-grade engine hardware upgrade designed to deliver maximum strength and reliability for high-performance VR38 builds. Manufactured in Germany from specially developed high-strength steel and finished with a durable burnished coating for corrosion protection, these Pro-Series studs provide significantly increased clamping force compared to factory head bolts, helping prevent head lift under extreme boost and cylinder pressures. Precision-engineered for a direct OEM-style fit, this complete stud kit is ideal for tuned street cars and track-driven GT-Rs that demand uncompromising durability and long-term engine stability.

High-Quality Materials and Production

• Wagner Tuning produces its Pro-Series 18.8 stud sets in Germany using a specially developed high-strength steel that achieves a tensile strength exceeding 1,850 N/mm² after heat treatment. Rather than using conventional cut threads, all threads are precision-rolled, increasing thread flank strength by approximately 30% for superior durability. Every Pro-Series product is finished with a corrosion-resistant nickel coating or, optionally, a blued finish, ensuring long-term protection and reliable performance even under the harshest operating conditions.

Easy Installation and Durability

• Wagner Tuning engineers its Pro-Series studs with an integrated hex socket drive on the head for precise and easy installation. A conical section on the engine block side ensures that, when tightened, the nuts seat correctly inside the threaded hole rather than on the thread flanks, protecting the threads during frequent assembly and disassembly in racing applications. One of the key advantages of Wagner Tuning’s Pro-Series over other manufacturers is the inclusion of matching high-strength nuts and, when required, washers in each kit, all rated to the same 1,850 N/mm² tensile strength standard.
