Why You Should Get A Custom Crate Engine For Your Jeep

No engine lasts forever. No matter how much you baby your pride-and-joy, the day will come when you realize the motor isn’t up to the job. Perhaps it starts burning oil, or maybe you’re tired of being passed by cars with more horsepower and torque. Whatever the trigger, sooner or later you realize something must be done.


Options for a Worn-Out Engine

For many Jeep enthusiasts, the first instinct is to pull the motor and rebuild it. Wiser heads may get out the checkbook, paying a specialist to build them a custom engine. We’re here to tell you there’s a third option — the custom crate engine.

A crate engine is so-called because it comes in — you guessed it — a crate. It’s a new engine, built to OE specs. That’s good, but it’s also bad.

It’s good because, with all-new components, you know the engine will last. It’s also bad because it has all the weaknesses and limitations of the original design. The 4.2L used in Jeeps from 1971 through 1990 is an excellent example. This puts out between 120 and 150 horsepower. That’s not a lot, especially by modern standards. If you’re spending a significant amount of money on a new engine, shouldn’t you get one that’s upgraded to modern standards? That’s the reasoning behind our 4.6L Jeep stroker engine.


Time for a Custom Crate Engine?

As a crate engine, our 4.6L stroker is pretty much a straight swap for what’s under the hood right now. However, the “stroker” part tells you you’re not getting an OE-spec engine. Instead, you’re getting a motor that’s substantially modified to deliver the power and torque you want and need. That’s why we call it a custom crate engine.

A “stroked” motor is one with a longer throw on the crank. This means more torque and, because the pistons sweep a greater volume, more displacement. The beauty of stroking a motor is that you can use the stock block — in this case the Jeep 4.2L or 4.0L — but in effect get a bigger, torquier engine.

If you want some numbers to back that up, from 4.6 liters of displacement, a Golen Engine custom crate Jeep engine makes 270 horsepower and 300 foot-pounds of torque.


Why Choose a Golen Engine Custom Crate Motor?

We get it, there are a lot of reasons you might want to rebuild your Jeep’s engine yourself. There are also some good reasons for not taking on this job.

Here’s a partial list:

  • Speed/time off the road: How long will that rebuild really take? Weeks? Months? In contrast, it’s perfectly possible to pull an old engine and drop in a crate unit in a weekend. That’s more time to enjoy your Jeep and less time wrenching in the garage.
  • Quality: Our 4.6L crate engine has been assembled by professional engine builders with years of experience. That’s why it comes with a three-year/unlimited mileage warranty.
  • Zero hassles: Our engines are dyno-tested and we offer a break-in service. When you turn the key on your 4.6L stroker it’s going to start, and it’ll pass emissions in all 50 states. Plus, should you run into problems, you have our unlimited technical support.


We understand the appeal of rebuilding an old engine, but for many Jeep owners we think a custom crate engine is a smarter option. We offer both long block motors and turn-key crate engines that dramatically improve on the stock 4.2 and 4.0. Call or email Golen Engine for more information.
