About ATK North America
With a history of remanufacturing engines that began in 1936, ATK focuses on delivering high-quality products that put power back under the hood and keep your wheels rolling through the toughest jeeping conditions. Like all the engines it produces, ATK's rebuilt Jeep 258 crate engine is constructed through careful reverse engineering processes. The result is a product that exceeds OEM standards while integrating under your hood seamlessly like the original version. Each ATK engine also comes with an unlimited mile warranty, so you can install any model inside your Jeep with confidence.
