Speedhut 4″ Street XL 8K RPM Shift-light Tachometer (R4-TC3-SXL)

The Speedhut 4″ Street XL 8K RPM Shift-light Tachometer (R4-TC3-SXL) is an essential instrument for monitoring your engine’s performance. This 4-inch gauge provides accurate readings of engine revolutions per minute (RPM) up to 8,000. Equipped with an intensely bright internal shift light, it allows drivers to optimize gear changes for improved performance and efficiency. Its compatibility with most gasoline engines utilizing standard spark plug ignition systems (1–12 cylinders) and tach signals over one volt makes it a versatile tool for a wide range of vehicles. The tachometer’s robust design and straightforward installation ensure it can reliably deliver real-time RPM data, helping you achieve peak engine responsiveness.
