P1 – Toyota 2JZ Main Stud Kit
12-Point Nuts | E190 Series | Black Oxide Finish
PN# K020-M01E

The P1 Toyota 2JZ Main Stud Kit (PN# K020-M01E) is engineered to deliver superior bottom-end stability, precise crankshaft alignment, and consistent main cap clamping for high-performance 2JZ engines. Manufactured for builders pushing substantial horsepower, high RPM, and elevated cylinder pressures, this kit provides the secure foundation required for serious street, drag, and motorsport applications.

Each stud is crafted from P1’s advanced E190 Series alloy, offering excellent tensile strength, durability, and fatigue resistance. This material is specifically chosen to maintain stable clamp load under extreme mechanical stress—ideal for engines running upgraded turbo systems, higher boost levels, or stroker and forged rotating assemblies. The E190 alloy ensures dependable main cap retention, helping reduce cap walk, minimize crankshaft distortion, and improve bearing life.

A protective black oxide finish enhances corrosion resistance while providing a professional, clean appearance during installation. Precision-engineered 12-point nuts and hardened washers ensure even torque distribution and reliable, repeatable fastening.

Perfect for high-output builds, this stud kit helps create a robust and stable lower end capable of supporting significant power increases.
