Info

Replace your timing chain with a Speedway gear drive. Unlike timing chains, a gear drive doesn't stretch, so your cam timing stays more accurate. By utilizing dual idler gears, they are more stable than single idler gear drives. This gear drive is as easy to install as a timing chain and will fit under your stock timing chain cover.

  • Easy to install
  • Compatible with all standard camshafts
  • SAE 660 silicon bronze rear thrust ring included
  • Rugged Cr40 alloy steel gears assure prolonged trouble-free operation
  • Axial needle and cage forward thrust bearings reduce friction
  • Designed for precise multiple cam timing adjustments
  • Absolutely no adverse wear to camshaft or valvetrain components
  • Dyno tests prove no horsepower loss compared to a chain

For use on Chevrolet Small Block engines 1957–1995 262-400 c.i. all without “FACTORY” hydraulic roller camshaft.

Note: This gear drive will not work with a factory roller cam.
