GPI LS3 Camshaft - LS SS2 - SS2
Street/Strip Powerhouse Camshaft for LS3, LS2 & LS1
The GPI LS SS2 Camshaft is engineered for street/strip enthusiasts who want harder-hitting top-end power while still retaining strong torque and solid drivability characteristics. Designed for LS3, LS2, and LS1 engines using 3-bolt cam hardware, the SS2 builds on the proven SS1 foundation but adds approximately 10 - 15 more horsepower up top with a stronger pull to 6700 RPM.
Tailored specifically for setups running a 3000+ RPM torque converter, the SS2 rivals SS1 torque output while extending the powerband for more aggressive acceleration. GPI recommends a 3200+ converter and upgraded rear-end gear ratios to fully take advantage of this profile.
A Proven Benchmark in LS Performance
Like all SS-Series grinds, the SS2 continues to uphold GPI's reputation as offering the best pound-for-pound LS camshafts on the market. These cams have become the standard for Camaros and Corvettes nationwide, delivering exceptional performance and unmatched real-world results.
GPI Camshaft and Head Packages featuring the SS-Series profiles have been dominating racetracks, pushing customer builds deep into the 10-second zone. The SS2 hits the sweet spot for enthusiasts who want more top-end power without jumping into full N/A race cam territory.
Ideal for N/A or Centrifugal Boost
Although the SS2 was designed for naturally aspirated engines, it translates extremely well to centrifugal supercharger setups thanks to its compatible, linear power curve. If you're N/A now and planning to add boost later, the SS2 remains a smart long-term cam choice.
Four SS-Series Variants
The SS-Series lineup includes four progressively aggressive profiles. The SS2 sits in the middle - more aggressive than the SS1 with stronger upper-RPM performance but still maintaining good manners for street/strip use.
