As demand has grown for the strongest possible hardware solution for large and dual pulley setups, 034Motorsport engineers developed the High-Strength Crankshaft Pulley Bolt Kit for enthusiasts who want an additional margin of strength and confidence. Designed specifically for the supercharged 3.0T engine, it is particularly well-suited for large 207mm crank pulleys, while remaining an excellent upgrade option for any crank pulley configuration.

Manufactured from high-strength tool steel with rolled M8x1.25 threads and a laboratory-verified tensile strength exceeding 220,000 psi, these bolts are engineered to withstand the highest loads the system can generate while maintaining proper installation torque. Each bolt features a hex-head design to help ensure secure retention after installation. Unlike factory stretch bolts, they are fully reusable, making them ideal for enthusiasts who frequently service or refine their setups.

  • Hex Head for Easy Installation
  • Tensile Strength Beyond 220,000 psi (1,517 N / mm²) [Laboratory Verified]
