About Truck Parts Cross

Founded in 2014, Diesel Laptops (our parent company) provides specialized diesel diagnostic equipment for the commercial truck, construction, automobile, agriculture, and off-highway markets. Diesel Laptops is the industry leader in diesel diagnostic tools and repair information. They pride themselves in being the diesel diagnostic experts and providing customers with world class customer service.

As an extension to our diagnostic software, we discovered the cross-reference software on the market was either expensive, restrictive, unreliable, or all three! So we decided to take our extensive database of truck parts, standardize it, and release it to the market for free. Why? Because the trucking industry needs to embrace technology, and we see it as our responsibility to lead. 

The end result is a huge database of parts that is updated daily and overseen by a team of people here at our headquarters in Irmo, SC. Sign up, use our software, and we look forward to making your parts searches easier!
