PN# K020-M02E

The P1 Toyota 2JZ Main Stud Kit for Dart Iron Eagle Blocks (PN# K020-M02E) is engineered to provide maximum bottom-end strength, precise main cap alignment, and exceptional clamping stability for high-power 2JZ builds utilising the Dart 4-bolt main configuration. Designed specifically for the increased rigidity and performance demands of the Iron Eagle block, this stud kit delivers the secure foundation required for extreme horsepower, high boost, and sustained high-RPM operation.

Each stud is manufactured from P1’s premium E190 Series alloy, delivering outstanding tensile strength and fatigue resistance. This material offers a consistent, repeatable clamp load that helps prevent main cap walk, minimises crankshaft distortion, and improves bearing life, critical in turbocharged, stroker, and fully forged engine combinations.

A high-durability black oxide finish protects the hardware from corrosion while maintaining a clean, professional look during assembly. Precision-machined 12-point nuts and hardened washers ensure smooth torque application and even load distribution across all 4-bolt main caps.

Built to support serious drag racing, roll-racing, street-performance, and full motorsport power levels, this kit gives your Dart Iron Eagle 2JZ bottom end the strength and stability it needs to survive extreme conditions.
