Longacre Racing Products Gauge Panel

Longacre Racing Products Gauge Panels: Built for the Demands of Real Racing

When a race car's engine pushes its limits, the driver needs instant, reliable data — and that's exactly what Longacre Racing Products delivers with their purpose-engineered gauge panels. Longacre is an established brand name in the auto racing industry, known for dedication to quality, innovation, and customer satisfaction. That reputation carries directly into their gauge panel lineup, where every design decision is made with the racetrack in mind.

Two Flagship Gauge Panel Lines

Longacre offers two distinct gauge panel series, each addressing the real-world challenges racers face under grueling conditions.

Digital Elite LED Waterproof Gauge Panels

The Digital Elite Waterproof Gauge Panels are engineered for wet and dirty environments, providing the absolute best in waterproof sealing. These LED-equipped panels are available in 3-, 4-, 5-, and 6-gauge configurations, covering critical vitals such as oil pressure, water temperature, oil temperature, water pressure, fuel pressure, and voltage — all in a single, compact panel. The bright LED readouts are designed for at-a-glance legibility even under the harsh lighting conditions of an enclosed cockpit or a sun-drenched oval.

SMi™ Elite Waterproof Gauge Panels

The SMi™ Elite Waterproof Gauge Panels are also engineered for wet and dirty environments, offering the same class-leading waterproof sealing in an analog-style format for racers who prefer traditional needle-and-dial instrumentation. Like the Digital Elite series, SMi™ Elite panels are available in multi-gauge arrangements covering oil pressure, water temperature, oil temperature, fuel pressure, tachometer, and more — giving teams the flexibility to build a panel suited to their specific monitoring needs.

Why Gauge Panels Matter on the Track

In motorsports, a single missed warning — a spike in oil temperature, a drop in fuel pressure, a surge in water pressure — can mean the difference between a podium finish and a blown engine. Pre-wired, all-in-one gauge panels like those from Longacre simplify cockpit wiring and reduce the chance of installation error, ensuring that every reading you see is accurate and trustworthy. The very first Longacre product was the Gagelite Warning Kit, and from that beginning, Longacre quickly expanded their product line to include pre-wired gauge and switch panels — making gauges a core part of the brand's DNA from day one.

A Legacy of Racing Innovation

Jack Jaynes started Longacre Racing Products in California in 1978. The company moved to Redmond, Washington in 1987 and later expanded to a larger facility, ultimately settling in a custom-built facility in Monroe, WA. Over the decades, Longacre has innovated many products now considered standard equipment — including dash and switch panels. Longacre customers include individual racers as well as some of the most respected names in modern-day racing.

Whether you're building a dirt late model, a circle track stock car, a kart, or a drag racing application, Longacre's gauge panels offer the reliability and readability that serious competitors demand.
