ARP Crankcase Bolt Kit for 1989-1994 Porsche 964

Fits 1989-1994 Porsche 964 models.

Ensure the structural integrity and sealing of your flat-six engine with the ARP Crankcase Bolt Kit. During a high-performance rebuild, original equipment hardware often fails to provide the consistent clamping force necessary to keep case halves perfectly aligned under high thermal and mechanical stress. These ARP fasteners are engineered to exceed OE specifications, providing the superior tensile strength required to prevent case shifting and the chronic oil leaks common in air-cooled Porsche engines.

This kit replaces the factory fasteners with high-strength hardware designed for precision torque loading. Whether you are performing a standard top-end refresh or building a high-compression track engine, these fasteners provide the reliability needed to maintain main bearing bore roundness and case-half seal integrity.

• Specifically engineered for the Porsche 964 engine architecture
• Delivers superior clamping force to prevent case movement
• High-strength construction for maximum reliability under extreme conditions
• Essential component for any professional engine overhaul or performance build
