Speedmaster PCE279.1018 Mopar Chrysler Big Block 383 440 12-Point Head Stud Kit

The Speedmaster PCE279.1018 head stud kit is engineered specifically for Mopar Chrysler Big Block 383 and 440 engines, providing superior clamping force and reliability for high-performance and racing applications. These precision-manufactured studs offer significant advantages over traditional head bolts by delivering more consistent torque loading and reduced cylinder head lift under extreme combustion pressures.

Premium Construction and Materials:

• Manufactured from aircraft-quality 8740 chromoly steel for exceptional strength and durability
• Cold-forged construction ensures molecular integrity and eliminates material defects
• Heat-treated prior to thread rolling and machining for optimal hardness
• Rated at 190,000 psi tensile strength for maximum clamping reliability
• Precision-rolled threads provide better fatigue resistance than cut threads

Complete Kit Includes:

• 12-point head studs for positive engagement and accurate torque application
• 12-point nuts designed for precise torque specifications
• Hardened parallel washers for even load distribution across the cylinder head

The 12-point design allows for finer torque adjustments in tighter increments compared to 6-point fasteners, while the hardened washers prevent galling and ensure accurate torque readings. This complete stud kit is ideal for engine builders seeking maximum head gasket sealing and long-term durability in both street and competition engines.
