PAC Racing 10-degree steel valve locks are the industry standard for reliable valvetrain performance. These locks are manufactured from high-strength steel with a durable black finish, ensuring long-term wear resistance under demanding conditions. The 10-degree lock angle provides a positive, secure grip on the valve stem, which is critical for maintaining consistent valve lash and preventing retainer failure in high-performance engines.
The .050 less height configuration is specifically designed to assist engine builders in achieving the correct installed spring height without needing additional shims. By providing a secure lock between the valve stem and the retainer, these PAC Racing components ensure that your valvetrain remains stable throughout the entire RPM range. These locks are a cost-effective yet high-quality solution for both street performance and competitive racing engines. Trust your engine's valvetrain to the precision engineering found at GGCRACING.
