In addition to replacement parts, Cooper provides reconditioned and exchange “zero hour” overhauled engines (dyno operated and approved), to better serve our customers’ requirements. To further enhance the performance of your legacy Waukesha VHP engines, our engineering team has developed many control modernization, ignition, and parts upgrades.
