Product Specs
  • Brand: Gage Motorsports
  • Product: Gage Black Venom Roller Rocker Arms
  • Ratio Option: 1:1.2 or 1:1.3
  • Commonly used with larger cams like DynoCams 356 and dual springs
  • We suggest only using chromoly pushrods with these rockers and cut to the proper length to maintain proper valvetrain geometry.
About Gage Rocker Arms:
  • The GAGE series rockers are by far the best rockers you can put on your engine. The shaft mount design adds strength, durability and frees up a ton of power by eliminating as much friction and drag as possible.
  • The roller tip design also reduces friction and wear, ensuring less heat buildup and more efficient operation. Whether you are building a race engine or upgrading your existing engine, the Gage Roller Rocker Arms are an excellent choice.
  • These rocker arms are made from premium materials, including aircraft-grade aluminum, which ensures their durability and long-lasting performance. With their lightweight design, they help reduce valve train weight and improve engine response, making them an excellent choice for high-performance racing engines.
  • Proudly manufactured in the USA
  • Don't be fooled by cheap imitations! These are the real deal and used by racers!
  • CNC machined from billet aircraft aluminum with a protective anodized coating
  • Needle bearings
  • Hardened roller tips and shafts
  • Dyno tested at 10,500rpm and proven to provide more horsepower
  • These, as tested, show a 3% increase in maximum torque and HP over standard aluminum rockers.
Please do the math (lift x ratio = total lift)
  • A .275" lift cam and 1.2 rockers will net .330" of lift at the valve
  • A .275" lift cam and 1.3 rockers will net .358" of lift at the valve
Compatible:
  • Honda GX390
  • Predator 420cc (Non-Hemi)
  • Most 13-16 HP Clone engines
