Reliable Clamping for RB20 and RB25 Engines

The ARP 202-4301 Head Stud Kit is the ideal solution for anyone upgrading their Nissan RB20DET or RB25DET engine. These engines are known for their responsiveness and tuning potential, but they require robust fastening solutions to maintain head gasket integrity under increased boost and performance tuning.

Why You Need ARP Studs

  • Enhanced Clamping: Provides significantly more clamping force than stock head bolts.
  • Durable Construction: Made from high-quality 8740 chromoly steel for long-lasting use.
  • Engineered for Performance: Specifically designed for the RB20 and RB25 engine series.
  • Complete Set: Includes all necessary studs, nuts, and washers for a professional installation.

Upgrading to ARP head studs is a critical step for any RB20 or RB25 engine build. Whether you are running a stock turbo or a larger aftermarket setup, these studs ensure that your cylinder head remains perfectly seated, preventing leaks and maintaining consistent compression. The stud design also makes cylinder head installation easier and more precise, allowing for accurate torque application. Don't let weak factory bolts compromise your engine's performance or reliability. Trust the industry-leading quality of ARP to keep your engine together under pressure.
