Hadley Parts

Hadley is an industry-leading manufacturer of pieces, parts, and hardware for light-, medium-, and heavy-duty applications. In addition to trucks, Hadley's product catalogue covers busses, RVs, trailers, transit vehicles, and specialty / industry equipment.

Despite the company's widespread success in the land-based world of manufacturing, Hadley didn't start out producing parts for land vehicles. Instead, Hadley was founded way back in 1945 with the goal of producing higher-quality safety equipment for sailors and other sea-based professionals. After the development of the Hadley Horn kicked off production for the company, multiple partnerships with sea-based manufacturers and distributors helped the company rise to the fame and success that it knows today.

After only a few short years, Hadley broke into the automotive industry and several others. Nowadays, the company services primarily land-based vehicular applications with products ranging from the horns that made the company famous to newer, more modern SmartValve technologies.

SmartValve is currently the company's leading brand, with much of its production going into that line of products. However, the company produces much more than just one line of high-quality electronic height-control systems. The company also produces horns, horn kits, shields, and an assortment of other miscellaneous valves intended to boost your vehicle or equipment's performance.

We at FindItParts have curated nearly 100 of the best pieces, parts, and hardware that Hadley has to offer. Whether you're looking for something simply to reduce back strain while operating your equipment or a better valve to beat your OEM specifications, you just might find it in Hadley.
