Step up to the next level of performance with the GPI LS3 SS3 Camshaft—the most popular cam in the GPI lineup, built for hardcore street and strip enthusiasts who want serious power gains without compromise.

Designed to deliver significantly more horsepower and torque than the SS1 and SS2, the SS3 cam is engineered for aggressive performance while maintaining the drivability needed for real-world use. With a strong powerband that pulls hard to 6900 RPM, this cam excels in high-RPM applications and thrives in properly geared setups—especially with 3.91 gears.

Track-tested and proven, the SS3 cam has helped countless builds push deep into the 10-second quarter-mile range, making it a benchmark choice for LS-powered Camaros, Corvettes, and beyond. Whether you’re building a competitive street car or a weekend track machine, this cam delivers the performance to back it up.

While optimized for naturally aspirated combinations, the SS3 also pairs exceptionally well with centrifugal superchargers, thanks to their similar linear power delivery. This makes it a smart choice for builders planning future upgrades—run it NA now, and add boost later without sacrificing compatibility.

Available in multiple variations ranging from aggressive street to full race configurations, the GPI SS3 cam offers the flexibility to match your exact performance goals.

If you’re looking for a camshaft that delivers proven results, strong top-end power, and real-world performance—this is it.
