What We Do
We specialize in heavy-duty truck diesel engines for over-the-road applications, and we also handle select smaller industrial models like the Caterpillar C4.4 and Perkins 3.3.
Founded in 2011, JSJ Diesel Sales has grown into one of the nation’s most trusted names in rebuilt and tested diesel engines. From our 30,000 sq ft Miami, Florida facility, we maintain 1,000+ engines in stock and ship fast across the U.S. and beyond.

Every engine is run-tested, with oil & coolant inspections, leak checks, and compression verification before it leaves our facility. Our mechanics bring 150+ years of combined experience to every build.
Need power or a specific spec? We build to suit. Example: taking a Cat MXS-475 to a 650 HP configuration—just one of the many performance paths we can deliver.
Customers return to JSJ because we stand 100% behind our engines with honest guidance and real support. And remember—JSJ never takes a core back.
