    It's time to grab the boggers get dirty! If you spend your weekends axle deep in gumbo, you know mudding is hard on your engine. Hazards lurk in the murky deep and sometimes gunning it results in a blown engine. 4WP stocks the Jeep 4.0 performance crate engine and ATK Jeep engines to get you back in the bog fast.

    Budget
    Replacing the engine is never fun and is almost always expensive. Deciding on a reconditioned or remanufactured or crate engine may be based solely on budget. However, if you've got some time and some flexibility in the budget, you can upgrade while replacing. Reconditioned engines can be cheaper, but they also can have shorter limited warranties and additional components. Remanufactured engines can come ready to install with customized upgrades, based on how hard you use your Jeep and what you're trying to achieve.

    Remanufactured Engines
    Although you should double-check, most of ATK remanufactured engines are a universal fit, which means you can focus on the specifications knowing that it will work with your Jeep. These high-quality engines have been reverse engineered. All Spartan remanufactured engines including blocks, cranks and heads are machined and tested. Removing these original factory defects save time and money on additional components and installation.

    Short Block vs. Long Block
    Short block engines are incomplete. Depending on the model, they may require additional parts including cylinder heads, gaskets and an oil pump. Buying and installing individual components can be costly and time-consuming. Long blocks can be bolted to the short block and are almost complete. Engine performance can be affected by the introduction of several individual external components. Since long blocks come with more parts, potential performance is better.

    When your engine grenades, go to 4WP for affordable quality replacement. Upgrading for horsepower and low-end torque can improve engine performance and capabilities. Our 90-day best price guarantee means you get the best price on that part. We'll get you back to Livin' the Jeep Life fast.
