Engineered for Demanding Applications
Manufactured from high-strength tool steel with rolled M8x1.25 threads, each bolt is independently laboratory verified with tensile strength exceeding 220,000 psi. Designed to withstand loads well beyond what the crank pulley system should experience, this kit offers a durable and reliable fastening solution for performance-oriented builds.
While the included hardware in 034Motorsport Crank Pulley Kits remains fully sufficient for upgraded pulley applications, this kit serves as a simple and confidence-inspiring add-on during installation.
Reusable & Easy to Install
Unlike factory stretch bolts, these bolts are fully reusable, making them ideal for enthusiasts who frequently service or refine their setup. Each kit includes Loctite for installation, while the hex-head design allows for straightforward installation and secure retention.
