Description
Proform LS Header Bolts 8mm x 1.25 Wedge Lock Nickel Set 12 66755
The Proform LS Header Bolts are precision-engineered fasteners designed specifically for securing headers on Chevrolet LS engine applications. Manufactured with high-grade materials, these bolts ensure durability and resistance against corrosion, thanks to their nickel plating. This plating not only enhances the aesthetic appeal but also provides additional protection against heat and wear, making them ideal for high-performance automotive environments.
With an 8mm x 1.25 thread size, these wedge lock header bolts offer a reliable and robust locking mechanism. The unique wedge lock design helps to maintain torque even under extreme conditions, ensuring that the bolts remain securely fastened during operation.

Each bolt is meticulously designed to ensure ease of installation while providing an optimal fit for the associated components. As a result, these header bolts play a significant role in promoting efficient exhaust flow and enhancing overall engine performance.
