Shock Inflator 300PSI Digital

The LONGACRE Shock Inflator 300PSI Digital is a precision diagnostic and tuning tool designed for suspension setup, shock maintenance, and performance calibration on race cars, street vehicles, and track platforms. Whether you're dialing in shock preload for autocross competition, checking nitrogen pressure on adjustable shocks, or maintaining baseline spring rates, this inflator delivers the repeatability and accuracy that serious mechanics and enthusiasts demand. The 0–300 psi range covers everything from light front-end geometry work to high-pressure rear suspension tuning on everything from road-course platforms to drag racing applications.

Built around a digital readout face for exact pressure confirmation, the Shock Inflator 300PSI Digital pairs mechanical reliability with electronic precision—eliminating parallax error and guesswork inherent to analog gauges. The controlled flow inlet restricts rapid pressure surges, protecting shock seals and preventing overpressurization during charging; this feature is critical when working with twin-tube or monotube designs where seal integrity directly impacts damping consistency. The 24-inch hose provides safe working distance from the shock body, reducing risk of accidental impact or temperature transfer during measurement. A silver carrying case protects the unit and hose assembly between jobs, keeping the gauge calibrated and ready for the next suspension adjustment session.

This tool is essential for any suspension-focused mechanic, track prep crew, or DIY enthusiast running coilovers, adjustable dampers, or performance monotube shocks that require nitrogen charge maintenance. Compatibility spans all modern shock designs—OEM adjustable systems, aftermarket coilover platforms, and racing-spec units from major manufacturers. Regular pressure checks ensure consistent damping behavior across temperature swings and extended track sessions, directly supporting both safety and performance predictability. The compact dimensions (9.4 x 5.6 x 12.2 inches) and lightweight build (3.35 lbs) make it an ideal pit bag or garage-wall addition for anyone serious about suspension tuning and maintenance.
