About Us

Welcome to our Automotive Gear Ratio Calculator portal. We are a dedicated team of mechanical technicians, gear design engineers, and racing enthusiasts who wanted to provide an advanced tool for drivetrain tuning and simulation.

Our Focus

We aim to deliver precise, robust calculation benchmarks for simple gear reductions, compound transmissions, and real-world vehicle speed simulators. By mapping rotational speeds and tire sizing dynamics, we help you optimize gearing configurations for drag racing, off-roading, and daily driving efficiency.

Engineering Standards

Our sizing calculations adhere to international mechanical engineering parameters. We provide calculations for standard planetary sets, tooth profiles, and sprocket-chain dynamics to ensure mechanical compatibility for your builds.
