Overview

The ZZP LTG Race Head Stud Kit is a performance upgrade designed for the 2.0L LTG engine. These studs feature a larger center shank (10.90mm vs. 10.24mm original) to provide better longevity and reliability under high horsepower conditions, preventing head lift above 500whp. The kit includes a specific torque sequence and passes for installation.

The kit is designed exclusively for ZZPerformance and fits the 2.0L LTG engine found in models such as the ATS, Camaro, CTS, Regal, and Malibu. Installation involves torquing the nuts in three passes: 25 ft/lbs for the first pass, 50 ft/lbs for the second, and 90 ft/lbs for the third, following a specified torque sequence.

The ZZP LTG Race Head Stud Kit is a specialized performance component engineered to enhance the durability and reliability of the 2.0L LTG engine, particularly in high-horsepower applications. Designed to address issues of head lift that can occur above 500whp, these race head studs feature a significantly larger center shank measuring 10.90mm, compared to the original ZZP head stud's 10.24mm. This enhanced design minimizes stud stretch, ensuring greater structural integrity and longevity for the engine under demanding conditions. This custom kit is exclusively manufactured for ZZPerformance and is tailored to fit the 2.0L LTG engine. It is commonly found in vehicles such as the Cadillac ATS, Chevrolet Camaro, Cadillac CTS, Buick Regal, and Chevrolet Malibu. The kit requires a specific installation procedure involving a three-pass torque sequence: 1st pass: 25 ft/lbs 2nd pass: 50 ft/lbs 3rd pass: 90 ft/lbs A detailed torque sequence is also provided to ensure proper and even clamping force across the cylinder head.
