GPI LS7 Cam - SS2 LS7 with 8620 Hardened Core Upgrade (2010 - 2015 Camaro Z/28 | 2014 - 2019 C7 Corvette Z06) - LS7STG2.1-8620
High-Durability Moderate-Idle Performance Cam for LS7 Engines
The GPI SS2 LS7 Camshaft with 8620 Hardened Core Upgrade is built for LS7 enthusiasts who want aggressive midrange and top-end performance with excellent long-term durability. The SS2 is known for its moderate performance idle, strong midrange torque, and extended power curve that pulls hard to 7200 RPM. The 8620 upgrade enhances longevity and reliability under high spring pressure and repeated high-RPM use.
Please note: This is a high-lift, 3-bolt LS7 camshaft requiring .660? dual valve springs and hardened pushrods. Increased compression is recommended for best performance.
Why Choose the 8620 Hardened Core?
GPI's proprietary 8620 hardening process produces a tougher, more wear-resistant camshaft surface while retaining the ductility of the alloy core. The result is a cam built to handle aggressive ramp rates, stiff spring pressures, and high-RPM abuse. For drivers who push their Z/28 or Z06 hard on the street or track, the 8620 upgrade offers a superior reliability margin.
Performance Profile: More Power Up Top, Same Strong Torque
The SS2 LS7 retains the torque-heavy characteristics of the SS1 but adds more horsepower in the upper ranges. It's ideal for street/strip builds, high-compression naturally aspirated setups, and cars planning future centrifugal supercharging thanks to its linear airflow characteristics.
LS7 Cam Series Overview
GPI LS7 camshafts dominate the LS performance market for a reason - they consistently deliver exceptional drivability, superior RPM stability, and unmatched horsepower gains. Whether NA or blown, these cams have become the standard for serious LS7 builds across the country.
The SS2 is the middle-ground option: more aggressive than SS1 while staying more streetable than full race variants.
