The 3/8in Hi-Tech Poly Lock is a precision-engineered valve train component designed for high-performance engine builds and competition applications. This lock collar secures pushrod geometry in aggressive cam profiles where standard retention methods may fail under extreme valve train loads. It is suitable for various engine types, particularly in racing and performance contexts.
Manufactured from hi-tech polymer material, the 3/8in lock delivers superior load-bearing characteristics while reducing mass compared to traditional steel collars. The poly construction resists corrosion and galling, eliminating the seizing issues common to metal-on-metal fastening systems. This design allows consistent clamping force across repeated thermal cycles, maintaining critical pushrod length specifications essential for valve timing accuracy.
Technicians rebuilding engines with aggressive cam profiles will find this lock indispensable for maintaining pushrod position and preventing catastrophic valve train separation during sustained operation. Its compatibility with standard pushrod sizing makes it a versatile choice for various engine builds, ensuring reliable performance in demanding conditions.
