We have a large selection of Jeep 4.0L crate engines, and if you're looking to get even more power out of your newer Wrangler, AEV offers complete Jeep V8 Hemi conversion kits for 07+ Wranglers. The swap couldn't be easier with AEV's complete kits that include everything you need, except for the engine and transmission, for a factory-like engine swap.
Why a Jeep Crate Engine is a Smart Upgrade
Crate engines are a more necessary upgrade than you might think. When the engine in your Jeep is tired, burning oil, or simply done, a crate engine is usually a smarter upgrade than fixing problems one Jeep OEM part at a time. A complete replacement motor drops in, ready to run with zero hassle.
A remanufactured engine from a builder like ATK is fully machined and backed by a lengthy warranty. For a bigger kick, a Jeep stroker engine adds displacement. The V8 crowd, on the other hand, will want a high-performance engine-swap kit to access serious power.

Frequently Asked Questions
Is it worth putting a new crate engine in an old Jeep? If the body and frame are solid, a new engine can be faster and cheaper than buying a new vehicle, and it gives your ride a fresh start. Make sure to follow the engine break-in procedure once you’re done.
Should I replace or rebuild my Jeep engine? A new pre-built engine gets you back on the road faster with a warranty, while rebuilding can, in some cases, cost less if you have the time and tools.
How do I know if my ride needs a new engine? Look for persistent oil burning, knocking sounds, or overheating. An engine replacement makes sense if repairs are piling up faster than you can keep up with them.
