GPI LS Turbo Camshaft - LS SS4 Turbo (2010 - 2015 Camaro | 2014 - 2019 C7 Corvette) - TC-STG4
Maximum-Power Turbo Camshaft for Street/Strip & Race LS Builds
The GPI TC-STG4 SS4 Turbo Camshaft is the most aggressive turbo grind in GPI's lineup for 6.0 - 6.2L LS engines. Designed for high-powered turbocharged 5th Gen Camaros and C6/C7 Corvettes, this cam delivers exceptional mid-range punch and explosive top-end power - ideal for street/strip cars and dedicated race builds running moderate to aggressive boost levels.
With a performance idle and a light, clean turbo lope, the SS4 provides the unmistakable sound of an advanced turbo setup while maintaining reasonable drivability when paired with the required supporting components.
Street/Strip Meets Race-Level Power
To unlock its full potential, the SS4 cam requires a high stall-speed torque converter, free-flowing race exhaust, and optimized gearing. This combination allows the cam to carry strong power through the upper mid-range and well into high RPM - perfect for competitive builds needing fast spool and a broad, usable boost curve.

With four turbo cam iterations from mild to full race, the SS4 sits at the top - designed for enthusiasts needing maximum turbocharger efficiency and high-RPM performance without sacrificing the drivability needed for street/strip versatility.
