JE-CO Diesel Dyno & Emissions recently upgraded our Eddy Current Chassis Dynamometers. This new air-cooled dyno allows for quick power checks and other short tests of medium- or heavy-duty single- or tandem-axle trucks and buses (basically anything over 14,001 GVW).
JE-CO was founded over 40 years ago. Over the years, diesel maintenance and repair became the primary revenue stream, with ancillary services in metal fabrication (trailer flatbeds, pup trailers, and racks).
Austin White and Mike Schwarz lead JE-CO Truck & Trailer with an aim to build a brand based on genuine customer service, honesty, and quality.Read the JE-CO Story
