When many Jeep owners first drive the 3.6L V6, it seems to feature the best of both worlds in power and fuel economy. However, once larger tires and bumpers are added, the Wrangler JK platform can seem sluggish. The next logical step is a re-gear, engine swap, or both. If you’re looking into an engine swap, the two more popular choices for the Wrangler JK are the 5.7L and 6.4L HEMI. If you want to swap in a 6.4L HEMI, a 392 Crate Engine may be for you. According to Arrington Performance, a stock 6.4L HEMI won’t hold up to certain performance mods, such as forced induction. As such, Arrington offers the 392 Crate Engine, based off the Chrysler 6.4L block, and replaces all of the moving parts with forged or matched high-performance parts. This makes the 6.4L design more durable and able to rev higher, work harder, and will increase overall power. In a vehicle such as a Jeep, where you may be out on a road trip or back in the woods, engine longevity and durability are a must, and we highly recommend the 392 if you’re looking to add performance modifications to a 6.4L, either during the engine swap process or down the road. There is no substitute for building it right the first time, especially where an engine is concerned! The Arrington 392 features 500 HP at the crank, and a 3 year or 36,000 mile warranty. If you’re looking to add an aftermarket built engine with the craftsmanship and attention to detail you’ve come to expect from the OEM, look no further. The 392 Crate Engine is perfect for both a 2-door or 4-door build, and will give the Wrangler JK platform a noticeable increase in power, great for those builds on 35” or 37” tires. Arrington Performance takes the best of MOPAR and the Jeep aftermarket and merges them into one dependable and rugged package, the 392 Crate Engine!
