Why Choose ARP 625+ Head Studs for Your M156 Engine?
The factory "torque-to-yield" head bolts stretch permanently during installation, leading to potential weaknesses, oil leaks, and loss of reliability in high-performance applications. Weistec's ARP 625+ Head Studs, made from aerospace-grade materials, solve these issues by offering unmatched strength, reliability, and reusability. Whether you're upgrading for increased performance or addressing stock oil leak problems, these head studs are a must-have for long-lasting engine performance.
Benefits
- Leak Prevention: Eliminates common stock M156 oil leaks caused by inadequate head-to-block connections.
- High-Power Capability: Enables reliable operation under extreme power levels.
- Durable and Cost-Effective: Reusable design eliminates the need for repeated replacements, saving time and money.
