Dart Head Stud Kit GM LS Next Iron Block 66130018B

Head studs are the foundation of a reliable, high-revving engine—especially in forced-induction LS builds where cylinder pressure demands absolute clamping force consistency. The Dart Head Stud Kit for GM LS Next Iron blocks eliminates the risk of head gasket failure and cylinder leakage that can plague stock or inadequate fastening solutions. When you're pushing power, you need fasteners engineered to stay tight.

This chromoly stud kit delivers the precision clamping load required for sustained high-boost applications and extended track sessions. The 12-point nuts ensure repeatable torque specifications and resist loosening under vibration—critical for competition engines where every run counts.
