GPI LS3 Camshaft - LS SS1 - SS1
The Legendary SS1 Camshaft for LS3, LS2 & LS1 Engines
The GPI LS SS1 Camshaft is widely considered one of the pound-for-pound best 3-bolt camshafts for LS3, LS2, and LS1 engines. Across the country, the SS1 has become a benchmark upgrade for late-model Camaros and Corvettes thanks to its unmatched blend of drivability, torque, and track-tested performance.
Engineered for cars with minimal modifications, the SS1 offers a stable 675 RPM idle, excellent low-end torque, and a smooth, quiet lobe design that promotes long valvetrain life. From street use to weekend drag racing, this cam delivers exceptional response and a strong powerband from off-idle to 6600 RPM.
Track-Proven with 10-Second Capability
GPI's cam and head packages featuring the SS-series grinds have been dominating racetracks nationwide, pushing customer Camaros and Corvettes deep into the 10-second range. The SS1 offers the perfect entry point - street-friendly manners with serious real-world performance.
Naturally Aspirated or Centrifugal Boost - Your Choice
Originally designed for N/A applications, the SS1 is also extremely effective with centrifugal superchargers. Because centrifugal blowers mirror the linear power delivery of a naturally aspirated engine, this cam transitions perfectly to boosted setups. If you're N/A now but plan to add boost later, the SS1 is a smart long-term choice.
Four Cam Variants for Any Build
The SS Series includes four unique versions ranging from near-stock manners to aggressive N/A race profiles. The SS1 is the mildest of the lineup - ideal for lightly modified cars that want strong gains without sacrificing drivability or idle quality.
Installation Requirements
The SS1 is a high-lift 3-bolt LS camshaft. For proper installation, you will need:
- Dual .660" valve springs
- Hardened pushrods
- 3-bolt cam conversion (for engines originally equipped with single-bolt cams)
Refer to the Cam Install Package above for recommended supporting components.
