An on-highway truck can accumulate mileage quickly, which can take a toll on the engine. A timely engine overhaul provides a cost-effective solution for restoring lost power and efficiency and prolonging the engine's life span. An overhaul is also less expensive than engine or vehicle replacement.

If you're in Alabama or the Florida Panhandle, Thompson Truck Source can provide complete truck overhaul kits that allow you to restore your vehicle's engine to like-new condition. Regardless of your truck's make, model, or year, you'll get everything you need to keep it on the road.


We offer four kit options to meet your unique truck engine overhaul needs in AL or FL:

  • Bronze: Choose this basic option if you notice oil, fuel, or coolant leaks. Each kit contains bottom and bearing rolls, so you can execute an engine reseal and stop the leaks.
  • Silver: If you're experiencing a decrease in truck power, excessive exhaust smoke, or increased oil consumption, servicing the engine with this overhaul kit can correct the issue. You'll get everything included with the Bronze package, as well as everything you need to perform a basic in-frame overhaul, including piston crowns, skirts, rings, and pins.
  • Gold: Consider purchasing this heavy-duty truck overhaul kit if you're experiencing all the issues that require the Silver kit and the inability to reuse the connecting rods. You'll get the Bronze package plus assembled Cat® Reman cylinder packs and a connecting rod.
  • Platinum: Choose the Platinum truck overhaul kit if you notice a decrease in power, an increase in oil consumption, or a drop in fuel efficiency combined with excessive exhaust smoke. You'll receive all the components in the Gold package and a Cat Reman cylinder head, injector set, head bolt set, water pump, and oil pump.

Every kit comes with an unlimited-mileage, 12-month parts warranty that covers parts, labor and resultant damage. Add Extended Service Coverage for 24, 36 or 48 months with no mileage or hour limitations for even more peace of mind.
