GPI LT1 Camshaft - SS3 LT (2014 - 2019 C7 Corvette) - SS3-LT
Hard-Hitting Street/Strip LT1 Camshaft for Maximum NA Power
The GPI SS3 LT Camshaft is the most popular street/strip grind in the GPI LT1 lineup - engineered for Corvette owners who want serious performance without stepping fully into race-only territory. Designed specifically for the 2014 - 2019 C7 Corvette LT1, the SS3 LT produces noticeably more torque and horsepower than the SS1 and SS2 profiles and pulls extremely hard all the way to 6900 RPM.
This cam is built for the hardcore street/strip enthusiast and pairs best with a 3600+ RPM torque converter. Track-tested, dyno-developed, and street-proven, the SS3 LT has earned its reputation as one of the strongest all-around LT1 camshaft upgrades available.
Proven LT1 Performance with Real Track Results
GPI Cam & Head packages built around the SS-Series have consistently pushed 6th Gen Camaros and C7 Corvettes deep into the 10-second quarter-mile range. The SS3 LT delivers the airflow, powerband, and stability needed to make an LT1 truly come alive - whether naturally aspirated or boosted.
Excellent with N/A or Centrifugal Superchargers
Although engineered for N/A LT1 engines, the SS3 LT pairs exceptionally well with centrifugal superchargers. Its linear power curve mirrors N/A characteristics, making it an ideal cam for owners planning to add boost at a later stage.
Five LT-Series Cam Options
GPI offers five LT1 camshaft profiles, from mild street manners to all-out race grinds (plus custom-spec options). The SS3 LT sits at the aggressive end of the street/strip category - stronger than SS1 and SS2 but still suitable for well-prepped street cars with the correct converter.
