Longacre 52-50290 TIRELIEF Setting Tool Fine-Tune Precision Standard Air Chuck

In long-distance racing, tire pressure doesn't stay static; as the tires heat up, the air expands and pressure rises, often pushing the car into a "loose" or "push" condition. TIRELIEF™ valves are designed to bleed off that excess pressure, but they are only as good as their calibration. The Longacre 52-50290 TIRELIEF™ Setting Tool is the essential instrument used to "bench set" your relief valves before they ever hit the track.

This tool allows you to simulate tire pressure in a controlled environment. Instead of trying to adjust your valves while they are mounted on a hot wheel in a busy pit, you can use this tool to precisely dial in the exact PSI at which you want the valve to open. For any team running "bleeders," this tool is mandatory to ensure that all four tires are reacting exactly as the setup sheet dictates.

Key Features

• Bench-Top Calibration: Allows you to set your TIRELIEF™ valves accurately in the shop or trailer, ensuring they are ready to perform the moment you go through tech.

• Fine-Tune Precision: Provides the controlled pressure environment needed to adjust the valve's internal spring tension to within a fraction of a PSI.

• Standard Air Chuck Interface: Designed to work with your existing shop air supply, making it a seamless addition to your tire maintenance station.

• Saves Critical Track Time: Eliminates the guesswork and "trial and error" of adjusting valves during practice sessions, keeping your driver on the track and focused on speed.

• Rugged Longacre Construction: Built with the same durability as their world-famous pressure gauges, featuring high-quality fittings and a clear, easy-to-read interface.
