Product Details

The Manley 46670GT-8 is a high-performance 1.5mm steel top compression ring designed for engine builds using a 3.700-inch bore diameter. Engineered by Manley Performance — a trusted name in high-performance and racing engine components — this gas-ported (GL) top ring is built to deliver superior sealing, reduced blowby, and improved combustion efficiency under demanding conditions.

Gas-ported top rings feature small radial or axial holes that allow combustion pressure to act directly behind the ring face, pressing it more firmly against the cylinder wall for a tighter seal. This design is especially beneficial in high-horsepower, forced-induction, and racing applications where cylinder pressures are elevated.

Key Features:

  • Bore Diameter: 3.700 inches
  • Ring Width: 1.5mm top compression ring
  • Ring Thickness: 3mm axial height
  • Gas-Ported (GL) Design: Enhances ring-to-wall pressure for superior combustion sealing
  • Steel Construction: Provides excellent durability and wear resistance under high-load conditions
  • Designed for high-performance, racing, and forced-induction engine applications

Manley Performance has been manufacturing premium engine components since 1947, and their piston ring lineup meets the rigorous demands of professional engine builders. The 46670GT-8 top compression ring is an ideal choice for builders seeking maximum ring seal in a high-revving or high-boost application.

I looked around for few months on where to go to purchase JBA headers for my 01 Tundra. I came across Autoplicity and their prices were untouchable. I even called to speak with a sales representative and he gave me a discount code for my purchase. I would highly recommend doing business and plan on doing more business with them.
