ABOUT GSC POWER-DIVISION
ENGINEERING
For more than two decades, GSC Power-Division has been dedicated to one mission: designing and manufacturing the highest performing 4-valve valvetrain components in the world.
What began as a passion for making engines perform beyond factory limitations has grown into one of the industry’s most respected manufacturers of high-performance camshafts and valvetrain components. Today, our products power everything from daily-driven street cars to championship-winning drag cars, Drift cars, road race machines, time attack builds, and world-record race programs across the globe.
Performance & Quality isn’t our marketing message—it’s our engineering standard.
PERFORMANCE
STARTS IN THE
VALVETRAIN
Every engine is only as capable as its ability to move air efficiently.
The camshaft is the brain of the mechanical engine, controlling every intake and exhaust event. Valve springs determine stability at high RPM. Valves, retainers, guides, and lifters all work together as a system. At GSC, we engineer these components as a complete package—not as individual parts.
That systems-based approach allows builders to push engines harder, rev higher, and produce more reliable horsepower.
Our focus has always been on maximizing airflow, maintaining valve control, and delivering durability under the harshest operating conditions.
ENGINEERING BEFORE
MANUFACTURING
Unlike many aftermarket brands that purchase finished products from outside suppliers, GSC develops and manufactures many of our products in-house at our South Carolina facility.
From billet camshaft machining and precision grinding to product development and quality inspection, we maintain tight control over every stage of production.
Every lobe profile is the result of extensive engineering, dyno validation, real-world testing, and continuous refinement.
We don’t simply copy OEM profiles—we develop our own.
That commitment has produced camshaft profiles trusted by professional engine builders and racers worldwide.

BUILT FOR THE
WORLD'S TOUGHEST ENGINES
Modern performance engines continue to evolve with technologies like direct injection, variable valve timing, variable valve lift, and increasingly higher RPM capability.
GSC engineers products specifically for these challenges.
Our product lineup includes:
- Performance billet camshafts
- Conical and beehive valve spring systems
- Titanium retainers
- Stainless steel intake valves
- High-temperature super alloy exhaust valves
- Precision manganese bronze valve guides
- Hydraulic lifters
- DLC-coated mechanical tappets
- Complete valvetrain solutions for today’s most demanding engine platforms
Every component is engineered to work together, giving builders confidence that their valvetrain is capable of supporting serious horsepower.
INNOVATION
NEVER STOPS
Performance is never finished.
Every year, GSC continues to invest in new engine platforms, advanced manufacturing technology, material development, and engineering capabilities.
As engines become more sophisticated, our commitment remains unchanged:
Build better products.
Solve more difficult engineering problems.
Help our customers go faster.
Innovation isn’t something we do occasionally.
It’s what we’ve built our company around.
THE GSC
DIFFERENCE
There are companies that manufacture parts.
There are companies that sell performance.
At GSC Power-Division, we engineer confidence.
Every camshaft profile. Every valve spring. Every valve. Every lifter.
Designed with one purpose:
To give engine builders the confidence to push harder, rev higher, and make more power than ever before.
