Welcome to Promar’s Modular Performance

Ford Modular engines have been around since the early 90’s. Ever since the first 4.6 Ford engine was introduced, Promar has been remanufacturing and improving on them. Exceptional quality, attention to detail and great customer service have made Promar and our remanufactured 5.4 Ford Triton engine a benchmark in the industry.

People love there Ford F-150 Lightning Trucks and at Promar 5.4 Lightning Engines is our specialty. With a state of the art full service machine shop we can offer you a higher quality 5.4 Supercharged Lightning engine for less money than our competition. Our remanufacturing process allows us to use good seasoned cores and turn them into the powerhouse of your dreams. By buying high priced parts in volume we save money and pass the savings on to you, our valued customers. The stock 5.4 Lightning engines have a very weak bottom end as well as weak spark plug threads. Ford built these engines inadequate to the amount of boost they have over stock, and definitely for the amount of boost you want to pump in! If you have increased or plan to increase your power output over stock you NEED one of our 5.4 Performance Lightning Engine!

We have been in the engine business for over 20 years with over 100 years combined experience. Our technicians have worked on the modular engines since their inception. Not like all of those “Johnnies” come lately.
