If you are a Jeep enthusiast, you know that the 4.0-liter engine is one of the most popular engines out there. It has been used in various Jeep models, including the Wrangler, Cherokee, and Grand Cherokee. However, if you want to take things to the next level, you can consider installing a Jeep 4.0 stroker kit.
What is a Jeep 4.0 stroker kit?
A Jeep 4.0 stroker kit is an aftermarket upgrade that increases the displacement of the engine. It involves replacing the stock 4.0-liter engine crankshaft with a longer stroke crankshaft, which increases the engine’s displacement to 4.6 or 4.7 liters.
The kit typically includes a new crankshaft, connecting rods, pistons, bearings, and gaskets. The installation process is relatively straightforward, and it can be done by a skilled mechanic or DIY enthusiast.
What are the benefits of a Jeep 4.0 stroker kit?
There are several benefits to installing a Jeep 4.0 stroker kit:
- Increased horsepower: The 4.0 stroker kit can increase the engine’s horsepower by up to 40%. This means that your Jeep will have more power and be able to tackle more challenging terrain.
- Improved torque: The stroker kit also improves the engine’s torque, which is essential for off-roading. You’ll have more low-end power, making it easier to climb hills and navigate through rough terrain.
- Better fuel efficiency: Despite the increased power, the stroker kit can improve your Jeep’s fuel efficiency. This is because the engine can operate at a lower RPM while still providing the same amount of power.
- Enhanced reliability: The stroker kit components are often made from high-quality materials that are more durable than the stock parts. This means that your engine will be more reliable and last longer.

For example, a 4.6-liter stroker kit can increase the engine’s horsepower from 190 to 260. Meanwhile, a 4.7-liter stroker kit can increase the horsepower to over 300. These numbers can vary depending on the specific kit and how it is tuned.
