Since 1936, ATK has been reconditioning and rebuilding engines, either to factory spec or loaded with high-performance upgrades. At JEGS, we're proud to carry a full line of crate engines from ATK, ideal for daily drivers, muscle cars or work trucks. These ATK reman engines are available for Chevrolet/GM, Ford, Mopar and AMC as well as Hyundai, Kia, Mazda, Mitsubishi, Toyota, Subaru and Jeep.

ATK motors are available in anything from a stock four-cyl to V6s and big block or small-block V8s; ATK performance engines are reverse engineered to spot any shortcomings in the OEM designs and improve on them with superior components. Their high-performance engines are all covered by a 24 month/unlimited mile warranty.

Engines are available as base engine (including short block, cam, cylinder heads, timing set, valve covers, oil pan and oil pump/pickup tube), mid-dress (including intake manifold, distributor, water pump, harmonic balancer and flex plate) or full engine. Along with engines, you can also find machined bare blocks, cylinder heads (for select makes and models), torque converters, short blocks, remanufactured axle assemblies, manual transmissions, steering racks and more, all with the same expertise and attention to detail that you'll find in ATK reman engines.

With such a wide selection of engines and parts (including base and mid-dress engines that you can build to your preferences), JEGS has got an ATK reman engine that would be a great fit for your vehicle and your needs, and all of them are an improvement on what came from the factory.
