Performance head bolt set by Fel-Pro. Heat-treated alloy steel with friction-controlled coating for precise, consistent clamping force on high-performance engines.
The Fel-Pro Performance Head Bolt Set is engineered to provide the precise, consistent clamping force required to maintain a perfect seal on high-performance cylinder heads. Manufactured from premium, heat-treated alloy steel, these bolts are designed to withstand the extreme tensile stresses and thermal cycling of modified and forced-induction engines.
Each bolt is precision-threaded and features a specialized, friction-controlled underhead coating that ensures accurate and consistent torque readings. This eliminates the risk of over-tightening or under-tightening, which can lead to head gasket failure, warped cylinder heads, or blown engine seals.
Designed as a direct, high-strength replacement for factory head bolts, the Fel-Pro Performance set includes all necessary washers and installation instructions. It is the ultimate choice for engine builders, racers, and performance enthusiasts who demand uncompromising reliability and maximum clamping force for their high-horsepower applications.
