CAT (Caterpillar) Specialists
Caterpillar left the on highway engine market, but plenty of C7, C13, and C15 (and legacy 3406E) trucks are still earning and they need shops that still know them. We service CAT on-highway and vocational diesels, from ACERT-era turbo and regen issues to injectors and full overhauls.
If you’re running a CAT powered truck, we’ll keep it alive and working.
