ARP Pro Series Connecting Rod Bolts – VW / Audi 1.8L, 2.0L, KR, ABF

When the engine operates under higher loads, the weak points in the assembly quickly begin to show. That's why ARP Pro Series connecting rod bolts are the right choice for any build where real reliability, not compromise, is sought.

These bolts are precision CNC machined to extremely precise specifications and are designed for maximum strength and security in high-stress engines. Compared to standard OEM fasteners, ARP offers much higher fatigue resistance and is fully prepared for the stress that comes with higher compression, more RPMs, and performance configurations.

Key advantages:

• Suitable for VW / Audi 1.8L and 2.0L, including KR and ABF
• ARP Pro Series quality
• Precisely CNC machined
• Heat-treated for maximum strength
• Threads are rolled, not just cut
• Up to 10 times higher fatigue resistance compared to standard fasteners
• Significantly more reliable than OEM connecting rod bolts
• Suitable for engines with increased fuel pressure and higher loads

Why is this an important upgrade?

In a performance build, fasteners are not where compromises should be made. Connecting rod bolts take an enormous load, and at serious RPMs or increased power, OEM solutions are often not enough. ARP Pro Series provides the assurance that the bottom end of the engine is properly prepared.

Suitable for:

• Engine overhaul
• Performance build
• High-compression setup
• Turbo / high-load configurations
• Reliable OEM+ or motorsport-oriented upgrade
