GPI LS3 Camshaft - LS SS3 - SS3
The Ultimate Street/Strip Cam in the SS-Series
The GPI LS SS3 Camshaft is the most popular choice for hardcore street/strip LS3, LS2, and LS1 enthusiasts who want maximum naturally aspirated performance without stepping fully into race-only cam territory. Pound for pound, the SS3 delivers more torque and horsepower than the SS1 and SS2, with a brutally strong powerband extending all the way to 6900 RPM.
Track-tested, developed, and proven, the SS3 has become a benchmark camshaft for high-performance Camaros and Corvettes nationwide. It thrives in aggressive builds and pairs exceptionally well with 3.91 rear gearing for explosive acceleration.
Street/Race Focused for Serious Enthusiasts
This cam is tailored for serious street/strip setups running a 3600+ RPM torque converter. It provides significantly more top-end pull than the SS1 or SS2 while retaining just enough street manners for aggressive weekend-driven cars. If you want a cam that hits hard everywhere while still being usable on the street, the SS3 sits right at that sweet spot.
Proven Results in Real Competition
GPI Camshaft and Head packages built around the SS-Series profiles have been dominating racetracks across the country, pushing countless customers into the 10-second range. The SS3 represents the midpoint between street capability and all-out N/A racing, earning its reputation as a go-to performance upgrade.
Excellent with N/A Builds and Centrifugal Boost
Although engineered for naturally aspirated combinations, the SS3 also performs incredibly well with centrifugal superchargers. Its linear, N/A-friendly power delivery carries over perfectly to blower setups, making it an ideal choice if your long-term plans include boost.
Four SS-Series Iterations
The SS-Series lineup includes four versions, each escalating in aggressiveness. The SS3 is designed for the enthusiast who wants to step beyond street-friendly profiles into a more serious performance cam without jumping all the way to the SS4 race grind.
