Our engineering development process is set up to design, test, produce and expedite deployment of vehicle improvements.

Repower

A replacement engine can provide military vehicles with new life and increased power, lengthening their service and lowering long-term cost.

Another option for returning older vehicles to service is our ReNEWed line of remanufactured engines and systems. These reliable, cost-effective replacements can often outperform the original, because they incorporate many new components that meet or exceed initial performance standards.

• Every part is cleaned and inspected
• All high-wear and damaged components are replaced
• ReNEWed engines come with new 2nd generation blocks, new heads, new camshafts and all OEM parts
• All ReNEWed engines are 100% factory-tested to ensure leak-free performance
