P1 Chevrolet LT1 Main Stud Kit – Gen V, 12pt Nuts, E190 Series, Black Oxide
PN# K003-M01E

The P1 Chevrolet LT1 Main Stud Kit for Gen V LT1 engines is engineered to reinforce the bottom end with superior strength, consistency, and reliability in high-performance applications. Designed specifically for the direct-injected Gen V platform, this kit replaces factory main bolts with precision-machined E190-series studs for improved main cap stability under extreme load.

Manufactured from our premium E190 material, each stud delivers an ultimate tensile strength of 190,000 psi, offering exceptional resistance to stretch and maintaining accurate cap alignment during high boost, high RPM, and extended endurance use. The included 12-point nuts and hardened washers ensure proper torque transfer and uniform clamping across the entire main web structure.

Finished in a durable black oxide coating for corrosion protection and clean presentation, this kit is the ideal upgrade for LT1 builds running forced induction, nitrous, high RPM naturally aspirated setups, or any application where OEM hardware is not enough.
