The AutoMeter 3 3/8 Sport Comp Mech is a mechanical speedometer engineered for drivers who demand reliable, real-time velocity feedback without electronic dependency. Designed for street and sport applications, this analog gauge delivers straightforward performance monitoring in a compact 3-3/8 inch diameter package. Whether you're building a classic hot rod, restoring a vintage machine, or upgrading a modern performance vehicle, this mechanical speedometer provides dependable operation and clear readability in all conditions.

This mechanical speedometer operates via a flexible cable drive system, eliminating the need for electronic sensors or complex wiring harnesses. The black face dial with white numerals and indicator needle provides high contrast visibility, while the 120 MPH maximum reading accommodates most street and sport driving scenarios. AutoMeter's Sport-Comp series features precision-engineered mechanical movements and quality construction designed to withstand vibration and temperature fluctuations common in performance driving environments. The compact 3-3/8 inch diameter allows for flexible dashboard or custom panel installation without consuming excessive gauge cluster space.

Mechanics, fabricators, and enthusiasts favor mechanical speedometers for their simplicity, durability, and independence from electrical systems. This gauge works with cable-driven speedometer setups common in street rods, custom builds, and older vehicles where electronic conversions may be impractical. Installation requires a compatible speedometer cable connection; verify your vehicle's existing drive mechanism before ordering. The lightweight 1.4 lb construction minimizes panel load while the compact dimensions (6.25 x 5.3 x 6.45 inches) fit standard gauge pod openings. Ideal for restorations, custom builds, and any application where mechanical reliability outweighs digital complexity.
