About Longacre Racing Products

Longacre Racing Products has been a cornerstone of the motorsports industry since Jack Jaynes founded the company in California in 1978. What started with the iconic Gagelite Warning Kit grew into one of the most respected and comprehensive lines of racing equipment in the world. Today, Longacre operates out of a custom-built facility in Monroe, Washington, where engineering, manufacturing, and shipping all happen under one roof — a testament to the brand's commitment to quality control and consistency.

From weekend oval racers to professional NASCAR-level teams, Longacre has earned its reputation by delivering instruments and tools that produce accurate, repeatable results lap after lap. Whether you're dialing in chassis balance, monitoring critical engine vitals, or managing tire pressures in the pits, Longacre builds equipment that racers can trust when every tenth of a second counts.

A Legacy Built on Innovation

One of Longacre's most celebrated achievements is the development of their Computerscales® electronic wheel scale system, which fundamentally changed how race teams approach vehicle setup and weight distribution. This spirit of innovation runs through every product category the brand touches. Over the decades, Longacre expanded from warning kits into pre-wired gauge panels — a natural evolution that gave racers a cleaner, more professional cockpit setup with critical engine data always in view.

Precision tire management is another area where Longacre excels. Their lineup of tire pressure gauges is designed with the accuracy that competitive racing demands, helping crews make informed tire decisions before and during race events. Paired with their renowned racing scales, teams can dial in corner weights and achieve the balanced chassis setup that separates front-runners from the field.

Longacre's catalog also extends to tires and essential safety and electrical components, including their line of battery disconnect switches — a required safety item at virtually every sanctioned racing event. The breadth of the Longacre lineup means racers can source critical setup and safety equipment from a single trusted manufacturer.

Who Relies on Longacre?

Longacre's customer base spans virtually every form of motorsport — circle track, drag racing, road course, karting, and off-road. Individual racers and top-tier professional teams alike turn to Longacre because the brand consistently delivers durable, accurate tools built to withstand the rigors of race day: long hauls to the track, pit lane abuse, and the demanding environments of competitive racing. Now part of the AFCO Performance Group, Longacre continues pushing forward with new innovations while honoring the precision-first legacy that has defined the brand for over four decades.
